Soberana 02

FINLAY-FR-2

cas 2543416-58-4

A SARS-CoV-2 vaccine comprising a conjugate of the spike protein RBD domain with tetanus toxoid (Finlay Vaccine Institute of Cuba)
Soberana 02
, is a conjugate vaccine developed by Instituto Finlay de Vacunas.[517]

Soberana 02, technical name FINLAY-FR-2, is a COVID-19 vaccine produced by the Finlay Institute, a Cuban epidemiological research institute. It is a conjugate vaccine. This candidate followed a previous one called SOBERANA-01 (FINLAY-FR-1).[2] Professor Ihosvany Castellanos Santos said that the antigen is safe because it contains parts instead of the whole live virus, and therefore it does not require extra refrigeration, like other candidates in the world.[3] According to the WHO candidate landscape vaccine document, this vaccine requires two doses, the second one being administered 28 days after the first shot.[4]

The name of the vaccine, Soberana, is a Spanish word that means “sovereign”.[5]

An overview of current COVID-19 vaccine platforms - ScienceDirect

Efficacy

It has shown an efficacy of 62% after only two doses, according to BioCubaFarma, though a pre-print or details of the study have not been released.[6][7][8]

Pharmacology

FINLAY-FR-2 is a conjugate vaccine. It consists of the receptor binding domain of the SARS-CoV-2 spike protein conjugated chemically to tetanus toxoid.[2]

Manufacturing

The spike protein subunit is produced in Chinese hamster ovary cell culture.[2] In a pre-print article scientists from Cuba explain details of the vaccines technology and production.[9][non-primary source needed]

In Cuba

The Cuban government says it is planning to produce 100 million doses of its vaccine to respond to its own demand and that of other countries.[12][13] Cuba has also suggested that, once it’s approved, it will offer the vaccine to tourists visiting the country.[14][15][16]

The production of the first batch of about 100,000 doses will start in April.[17] José Moya, representative of the World Health Organization and the Pan American Health Organization (PAHO) in Cuba, suggested that after the vaccine passes all clinical stages, it could be included as part of PAHO’s Revolving Fund.[18]

The roll-out began with an “Interventional Trial”[19] that consisted of inoculating 150,000 at-risk participants which seems to be defined as health-care workers.[20][21] On April 11, 2021, the Ministry of Public Health of Cuba announced that 75,000 health-care workers were inoculated with their first dose of either of the two Cuba’s Phase III vaccines (the other being Abdala).[22][23]

Outside Cuba

Vietnam, Iran, Venezuela, Argentina,[24][25][26] Pakistan, India, the African Union, Jamaica and Suriname[27] have expressed interest in purchasing the vaccine, although they are waiting on Phase 3 results.[28][29]

Iran has signed an agreement to manufacture the vaccine[30] and Argentina is negotiating one.[24][25][26] Additionally, the Cuban government offered a “transfer of technology” to Ghana and will also supply “active materials” needed to make the vaccine.[31][32][33]

While the price is currently unknown, the commercialization strategy of the vaccine will be a combination of the “impact on health” and the capability of Cuba’s system to financially support “the production of vaccines and drugs for the country”, per the director of the Finlay Institute, Vicente Vérez.[34]

Clinical trials

Phase I

FINLAY-FR-2, which started being developed in October 2020, had 40 volunteers for its Phase I, according to the Cuban Public Registry of Clinical Trials, with an open, sequential and adaptive study to assess safety, reactogenicity and explore immunogenicity of the vaccine.[35]

Phase II

Phase IIa involved 100 Cubans, and phase IIb of the vaccine will have 900 volunteers between 19 and 80 years.[36][37] Vicente Vérez, director general of the Finlay Vaccine Institute, said that the vaccine has shown to give an immune response after 14 days.[38] The second phase has been supervised by Iranian officials from the Pasteur Institute.[5]

Phase III

Phase III commenced at the beginning of March as originally scheduled,[39][15] and “ready to publish” results are expected by June.[40][41][42] The trial volunteers are divided into three groups: some will receive two doses of the vaccine 28 days apart, another group will get two doses plus a third immune booster (Soberana Plus[43][44][45]), and the third a placebo.[39]

Although the trials involve thousands of adult volunteers recruited in Havana,[46] Cuba’s public health officials have said that they will also need to conduct phase III trials abroad because the island doesn’t have an outbreak of sufficient scale to produce meaningful statistics on vaccine protection.[5][14]

On March 13, 2021, the Cuban Biotechnology and Pharmaceutical Industries Business Group (BioCubaFarma) announced on social media that it had sent 100,000 doses of its Soberana 02 coronavirus vaccine candidate to the Pasteur Institute of Iran for clinical testing, “as part of the collaboration with other countries in the development of COVID-19 vaccines.” [47]

On April 26, 2021, it was reported that a Phase III conducted by the Pasteur Institute of Iran was approved to be started in Iran[48][49][50] It was previously reported that the Institute will host Phase 3 but the pre-requisites were “technology transfer and joint production”.[51][5]

Mexico plans to host a phase 3 trial.[52]

Interventional Study

The “Interventional Study” is set both in Havana,[53] Cuba’s capital and Santiago de Cuba, Cuba’s second most populous city [54][55] and in other provinces.[56] On May 6, 2021, the Finlay Institute of Vaccines announced on social media that the following adverse events have been observed: injection site pain (20%), inflammation at the injection site (5%), and general discomfort (5%).[57][58]

The CureVac COVID-19 vaccine is a COVID-19 vaccine candidate developed by CureVac N.V. and the Coalition for Epidemic Preparedness Innovations (CEPI).[1] The vaccine showed inadequate results in its Phase III trials with only 47% efficacy.[2] The European Medicines Agency stated that: “(…) medicine developers should design studies to demonstrate a rate of efficacy of at least 50%.”[3].

The CVnCov Vaccine (or CV07050101) is in development by CureVac AG. The vaccine uses mRNA technology to create a protein associated with SARS-CoV2, and upon administration and replication, to initiate subsequent immune responses in the body. As of June 2020, the company received regulatory approval from German and Belgian Authorities to commence Phase 1 clinical trials of this vaccine (NCT04449276).

Efficacy

On 16 June 2021,[4] CureVac said its vaccine showed 47% efficacy from its Phase III trial. This was based on interim analysis of 134 COVID cases in its Phase III study conducted in Europe and Latin America. The final analysis for the trials requires a minimum of 80 additional cases.[2]

Pharmacology

CVnCoV is an mRNA vaccine that encodes the full-length, pre-fusion stabilized coronavirus spike protein, and activates the immune system against it.[5][6][7] CVnCoV technology does not interact with the human genome.[6] CVnCoV uses unmodified RNA,[8] unlike the Pfizer–BioNTech COVID-19 vaccine and Moderna COVID-19 vaccine, which both use nucleoside-modified RNA.[9]

Manufacturing

Manufacturing of mRNA vaccines can be performed rapidly in high volume,[10] including use of portable, automated printers (“RNA microfactories”) for which CureVac has a joint development partnership with Tesla.[11]

mRNA vaccines require stringent cold chain refrigeration throughout manufacturing, distribution and storage.[12][13] The CureVac technology for CVnCoV uses a non-modified, more natural mRNA less affected by hydrolysis, enabling storage at 5 °C (41 °F) and relatively simplified cold chain requirements that facilitate up to three months of storage and distribution to world regions that do not have specialized ultracold equipment.[6][10]

CureVac has a European-based network to accelerate manufacturing of CVnCoV, if proven safe and effective, for production of up to 300 million doses in 2021 and 600 million doses in 2022.[10][14] An estimated 405 million doses will be provided to EU states.[14]

Clinical trials

In November 2020, CureVac reported results of a Phase I-II clinical trial that CVnCoV (active ingredient zorecimeran) was well-tolerated, safe, and produced a robust immune response.[15][16]

In December 2020, CureVac began a Phase III clinical trial of CVnCoV with 36,500 participants.[17][18] Bayer will provide clinical trial support and international logistics for the Phase III trial, and may be involved in eventual manufacturing should the vaccine prove to be safe and effective.[19][20] In February 2021, the EU’s CHMP started a rolling review of CVnCoV.[21][22] In April 2021, the same procedure began in Switzerland.[23]

Brand names

The manufacturer currently markets the vaccine under the name CVnCoV.[24] Zorecimeran is the proposed international nonproprietary name (pINN).[25]

Vaxine's promising new COVID-19 vaccine candidate

Vaxine’s promising new COVID-19 vaccine candidate

A new multivalent COVID-19 vaccine developed by Australian company Vaxine to tackle the new virus variants could be game-changer in the fight against COVID-19 

The world desperately needs a vaccine that blocks virus transmission and protects against all the variants. Covax-19 vaccine may soon change history”— Sharen Pringle, Vaxine Business Mananager

ADELAIDE, SA, AUSTRALIA, May 16, 2021 /EINPresswire.com/ — Professor Petrovsky, who is the Chairman and Research Director of Australian-based Vaxine Pty Ltd, explains that the two biggest challenges to tackling the COVID-19 pandemic are to develop a vaccine that completely prevents virus transmission something other COVID-19 have not been completely successful in achieving, and the second being to find a vaccine that protects equally against all the evolving immune-escape variants.

Professor Petrovsky has been researching coronavirus vaccines for the last 17 years, having previously published scientific papers on vaccines against both the SARS and MERS coronaviruses, which were highly protective in relevant animal models. He also recently published data from a collaboration with the US Army on development of a promising Ebola vaccine that protected mice against this most lethal disease after just a single vaccine dose. He has now successfully taken the same approach to design a protein-based vaccine against COVID-19.

Studies in a broad range of animal models including mice, hamsters, ferrets and monkeys, have recently revealed the high potential of this vaccine that is currently known as Covax-19(TM), but which likely will be soon rebranded as in its latest iteration it moves into late stage human trials in a number of countries.

Recent breakthrough data generated by Vaxine’s partner, Professor Kaissar Tabynov who leads the International Center for Vaccinology at the Kazakh National Agrarian University has shown that Vaxine’s unique spike protein antigen which is produced using insect cells in culture, was unique in that it not only totally protected hamsters from infection themselves but also prevented them from transmitting the virus to unvaccinated animals that were placed in the same cage two days after the vaccinated animals had been challenged with virus. Protection against transmission was not seen in hamsters given other vaccines making this finding unique to Vaxine’s spike protein antigen.

This hamster data reinforced findings in hamster, ferret and monkey challenge study performed by collaborating US Universities, who showed that two doses of Vaxine’s Covax-19 vaccine provided complete clearance of recoverable virus from the lungs and nose of animals when sampled just days after an infectious challenge.

“COVAX-19 vaccine has now been shown to be highly protective against the original Wuhan strain of the virus in hamster, ferret and monkey infection models performed by independent academic institutions in multiple countries, attesting to the strength of our protein-based vaccine approach”, says Prof. Petrovsky.

“A key element in the success of Covax-19 vaccine is the inclusion of Vaxine’s Advax adjuvant technology which acts as a turbocharger to drive an optimal immune response against the virus” explains Prof. Petrovsky who has been working on this promising vaccine adjuvant technology for the last 20 years with funding support from the US National Institutes of Health.

“We have now shown that our COVAX-19 vaccine can provide effective immunity including an ability to block nasal virus replication and this in turn successfully prevents transmission of the virus to vaccine-naïve animals,” he explains.

Follow on studies to confirm and expand upon these initial findings are currently underway at several US universities as well as Kazakh National Agrarian University, with a manuscript describing some of the initial animal data currently under review at a leading vaccine journal.

In another major breakthrough the team has now developed the vaccine into a multivariant format designed to protect against all the recently described variant strains of COVID-19, with work also underway on the most recently described Indian strains.

While the data is still preliminary says Prof. Petrovsky, the immune responses to the multivalent vaccine in mice are generating equally strong antibody binding activity against all the major virus variants. “This is extremely exciting as the world desperately needs vaccines able to protect against all the new strains of the virus including the UK, South African and Brazilian strains. By contrast , the currently available vaccines are clearly not as strong against some of these variants as they are against the original Wuhan strain” he explains.

Already there have been multiple confirmed cases of vaccine breakthrough where otherwise healthy individuals who have received mRNA, adenovirus or inactivated whole virus vaccines have become infected generally with either the South African or Brazilian variants.

This problem of immune-escape will only get worse over time as more complex variants emerge which is why Vaxine has been putting all its energy into finding a robust solution to this issue before proceeding with Phase 3 clinical trials of its Covax-19 vaccine.

Dr. Petrovsky went on to conclude “Now we have a multivalent formulation of Covax-19 vaccine that is showing high promise in animal studies, we plan to work as fast as we can to advance this new vaccine formulation in human trials, while expanding manufacturing capacity to ensure we are able to produce enough vaccine to meet the enormous global demand that will be attracted by such a successful vaccine.”

“To help us in this task Vaxine is looking to assemble a global network of partner organisations in countries around the world to assist Vaxine with vaccine development, clinical trials, manufacturing, distribution and sales. This is going to be a mammoth effort as we go to war against this insidious virus that continues to wreak havoc around the globe, with WHO recently predicting that the second year of the pandemic is likely to be much worse even than the first, an ominous warning for many countries that still remain poorly prepared and lacking in local vaccine manufacturing capability.

Vaxine wishes to help developing countries to establish their own local state-of-the-art vaccine manufacturing facilities, providing advice on appropriate facility design and undertaking technology transfer of its state of the art protein production technology to such facilities.

Countries in the developing world can no longer afford to sit and wait for outside organisations like COVAX to solve their vaccine supply problems, instead Vaxine proposes to help such countries find their own local solutions to the vaccine supply bottleneck for this.

Currently, the Australian influenza vaccine and adjuvant specialist and the Polish protein drug maker have just inked a memorandum of understanding, so the terms of a future contract remain to be defined. However, the technology behind is interesting.

The partners intent to utilize an insect cell-based recombinant spike protein of SARS-CoV–2 in combination with Vaxine’s proprietary Advax™ adjuvant and have already started Phase I testing in Australia with first result expected later this month. The company announced it will use artificial intelligence to evalutate clinical data in real time and announced the ambition to complete Phase II and III trials at the end of this year. “Supported by Microsoft technology, we aim to collect and analyse the COVAX-19™ trial data in real time, rather than waiting until the end of the trial before seeing if the vaccine is working, which is the traditional process,” said Vaxine’s Research Director Professor Nikolai Petrovsky from Flinders University in Adelaide.

Preclinically, Vaxine Pty Ltd’s syntetic spike protein with the company’s non-inflammatory Advax™ adjuvant, induced antibody and T-cell immune responses against the co-administered antigen. In various animal models, Covax-19 vaccination provided robust protection against an infection with the novel coronavirus.

The Phase I of Vaxine Pty Ltd in running since July in 40 healthy volunteers. If results are positive, the Australian vaccine maker is to expand studies and manufacturing to Europe. Under a future agreement Mabion SA would lead clinical development, manufacturing, regulatory negotiations and could exclusively market the vaccine in the EU and – optionally – in the US……..https://european-biotechnology.com/up-to-date/latest-news/news/mabion-to-licence-covid-19-jab-from-vaxine-pty-ltd.html

Arcturus previously announced that the ARCT-021 Phase 2 study had been approved to proceed by the Singapore Health Sciences Authority (HSA), who reviewed the same data as reviewed by the FDA. These Phase 1/2 study results demonstrated favorable tolerability and both humoral and cellular immunogenicity following administration of ARCT-021.

The Phase 2 study will enroll 600 participants, with 450 receiving ARCT-021 and 150 receiving placebo. Both older and younger adult participants will be included. Early interim analyses of safety and immunogenicity will be performed to inform dose selection for a Phase 3 study, which is targeted to start in Q2 2021, if the Phase 2 study is successful.

“Allowance of the IND for our ARCT-021 Phase 2 clinical study represents an important milestone for the program and we look forward to starting to screen study participants at U.S. and Singapore clinical sites very soon,” said Steve Hughes, M.D., Chief Medical Officer of Arcturus. “We have advanced ARCT-021 to Phase 2 based on promising interim results from our Phase 1/2 study and extensive preclinical data. Our prior clinical results show that ARCT-021 administration results in humoral and cellular immunogenicity, and we are encouraged by an increasing body of evidence highlighting the potential importance of T cells in providing protection against SARS-CoV-2 infection and COVID-19. We believe that ARCT-021 holds promise to be a highly effective vaccine with a differentiated clinical profile, including the potential to only require a single dose for protection.”

The SARS-CoV-2 virus is responsible for the COVID-19 pandemic. The pandemic emerged from Wuhan Province in China in December 2019 and was declared by the WHO Director-General a Public Health Emergency of International Concern on 30 January 2020.

In this study, a vaccine developed by IIBR for SARS-CoV-2 virus will be assessed for its safety and potential efficacy in volunteers. The study is comprised of two phases, a dose-escalation phase (phase I) during which subjects (18-55 years old) will be randomly allocated to receive a single administration of IIBR-100 100 at low, mid or high dose or saline or two administrations of IIBR-100 at low dose, or saline, 28 days apart.

Based on results obtained during phase I, and cumulative phase I data review, the expansion phase (phase II) has begun, during which larger cohorts as well as elderly age subjects will be randomly allocated to receive a single administration of IIBR-100 at low, mid or high dose or saline, or two administrations of IIBR-100 at low, mid or high dose (prime-boost) or saline, 28 days apart. Additional top-dose (prime-boost) may be implemented when immunogenicity of any prime-boost arm is considered insufficient.

Based on immunogenicity preliminary data and DSMB recommendations, the two administrations of mid, high and top dose (prime-boost) or saline will continue.

The subjects will be followed for a period of up to 12 months post last vaccine administration to assess the safety and efficacy of the vaccine.

Israeli institute’s COVID vaccine candidate said very effective in animal trials

Secretive Israeli research center’s shot shows near 100% efficacy in non-human trials, is on par with US company Moderna’s candidate, TV report says

Israeli researchers at a top secret research center have made progress on a coronavirus vaccine that shows a high level of effectiveness in animals, according to a Friday TV report.

However, there is no guarantee that the vaccine under development will be effective in humans, or will be available soon.

The Israel Institute for Biological Research (IIBR), a secretive unit that works under the Prime Minister’s Office, developed a vaccine that shows close to 100 percent protection against the virus in lab animals, the Channel 12 report said, citing “a security source.”

The vaccine under development is on par in effectiveness with a vaccine being developed by US biotechnology company Moderna, the report said.

Unlike vaccines developed abroad, the domestic vaccine will first be delivered to Israeli citizens, it added. If successful, it was expected to provide protection against the disease with a single dose.

The institute has not started human trials but was preparing to manufacture 10 to 15 million doses, report said.

Hebrew media have reported on potential breakthroughs at the shadowy institute several times before, starting in mid-March, with the Defense Ministry pushing back on some of the claims to tamper expectations.

IIBR said last month that it had completed successful coronavirus vaccine trials on rodents, paving the way for further testing on other animals and then possibly human trials.

In a paper published on the website of bioRxiv, an online repository for papers that haven’t yet been peer-reviewed, the institute, which is based in Ness Ziona, said it hopes to have a finished vaccine in a year, or possibly even earlier.

In the abstract of the report, the researchers say their vaccine, which they tested on hamsters, “results in rapid and potent induction of neutralizing antibodies against SARS-CoV-2,” the virus that causes COVID-19.

Earlier this month a vaccine adviser to the government cautioned that there was no guarantee that the shots being developed will prove widely effective.

In May, the institute confirmed that it had isolated an antibody it believed could be used to develop treatments against the virus. The development would not be useful in the creation of a vaccine, but would rather be a move toward a drug treatment for those who have already contracted the disease.

Tal Zaks, Moderna’s Israeli chief medical officer, described to Channel 12 on Friday the company’s push into Phase 3 testing of its vaccine candidate, which was developed with the National Institutes of Health, and began its first injections Monday.

The trial, the world’s largest vaccine study, plans to test the vaccine on 30,000 volunteers.

There’s still no guarantee that the experimental vaccine, developed by the National Institutes of Health and Moderna Inc., will really offer protection.

“The first time we saw the first model, that the vaccine, even if it’s just in mice, successfully stimulated the immune system to identify the virus and neutralize it, I knew that we hadn’t missed anything, that we had the correct vaccine,” he said.

“And of course the second ‘ah-ha’ moment was when we saw the first clinical results, when it was clear that in humans we weren’t just getting to antibody levels we were seeing in sick people, which is what we aspired to, but we were getting to even higher levels,” Zaks said.

Last month Israel signed a deal with Moderna for the potential purchase of its coronavirus vaccine if it ends up proving effective.

Moderna said the vaccination was administered in Savannah, Georgia, the first site to get underway among more than seven dozen trial sites scattered around the country.

Several other vaccines made by China and by Britain’s Oxford University earlier this month began smaller final-stage tests in Brazil and other hard-hit countries.

The massive studies aren’t just to test if the shots work — they’re needed to check each potential vaccine’s safety. And following the same study rules will let scientists eventually compare all the shots.

It normally takes years to create a new vaccine from scratch, but scientists are setting speed records this time around, spurred by knowledge that vaccination is the world’s best hope against the pandemic.

If everything goes right with the final studies, it still will take months for the first data to trickle in from the Moderna test, followed by the Oxford one.

Governments around the world are trying to stockpile millions of doses of those leading candidates so if and when regulators approve one or more vaccines, immunizations can begin immediately. But the first available doses will be rationed, presumably reserved for people at highest risk from the virus.

Coronavirus cases in Israel rose by 1,791 in 24 hours on Friday and the national death toll hit 512, according to the latest Health Ministry figures.

The total case count stood at 70,970, with 320 patients in serious condition, including 98 on ventilators. The number of recovered patients reached 43,850.

Israel has the fifth-highest number of new coronavirus infections per capita in the world, overtaking the United States, according to data compiled by a scientific publication based at Oxford University.

And while Israel has seen the number of new coronavirus cases rocket to more than 2,000 a day in recent weeks, a new Hebrew University report published on Thursday asserted that Israel has managed to gain control of the second wave of the coronavirus, thanks to a recent stabilization in the number of seriously and moderately ill patients.

The curve for seriously and moderately ill patients began to spike in late June before stabilizing in recent days, the researchers reported. They credited the restrictions imposed by the government in recent weeks to limit crowding for helping to flatten the curve.

According to the report, the death toll will climb by roughly 200 in the coming three weeks as a result of the high infection rate over the past month.

Experts have blamed a too-speedy reopening and the lack of an effective contact-tracing program as main factors in the virus resurgence, which has come as new daily coronavirus cases around the world have also reached record highs.

Cuban president praises progress of Abdala vaccine against Covid-19

ABDALA

CIGB-66, is a COVID-19 vaccine

Cuba says Abdala vaccine 92.28% effective against coronavirus

The announcement came just days after the government said another homegrown vaccine, Soberana 2, has proved to be 62% effective with just two of its three doses.

  • June 22, 2021, 10:03 IST

HavanaCuba said on Monday that its three-shot Abdala vaccine against the coronavirus has been proved 92.28% effective in last-stage clinical trials.

The announcement came just days after the government said another homegrown vaccine, Soberana 2, has proved to be 62% effective with just two of its three doses.

“Hit by the pandemic, our scientists at the Finlay Institute and Center for Genetic Engineering and Biotechnology have risen above all the obstacles and given us two very effective vaccines,” President Miguel Diaz-Canel tweeted.

The announcement came from state-run biopharmaceutical corporation BioCubaFarma, which oversees Finlay, the maker of Soberana 2, and the Center for Genetic Engineering and Biotechnology, the producer of Abdala.

Both vaccines are expected to be granted emergency authority by local regulators shortly.

Cuba, whose biotech sector has exported vaccines for decades, has five coronavirus vaccine candidates.

The Caribbean’s largest island is facing its worst Covid-19 outbreak since the start of the pandemic following the arrival of more contagious variants, setting new records for daily coronavirus cases.

The Communist-run country has opted not to import foreign vaccines but to rely on its own. Some experts said it was a risky bet but it appears to have paid off, putting Cuba in position to burnish its scientific reputation, generate much-needed hard currency through exports and strengthen the vaccination drive worldwide.

Several countries from Argentina and Jamaica to Mexico, Vietnam and Venezuela have expressed an interest in buying Cuba’s vaccines. Iran started producing Soberana 2 earlier this year as part of late-phase clinical trials.

Cuba’s authorities have already started administering the experimental vaccines en masse as part of “intervention studies” they hope will slow the spread of the virus.

About a million of the country’s 11.2 million residents have been fully vaccinated to date.

Daily cases have halved in the capital, Havana, since the start of the vaccination campaign a month ago, using Abdala, according to official data.

Cuba has reported a total of 169,365 Covid-19 cases and 1,170 deaths.

ABDALA, technical name CIGB-66, is a COVID-19 vaccine candidate developed by the Center for Genetic Engineering and Biotechnology in Cuba.[1][2] This vaccine candidate, named after a patriotic drama by Cuban independence hero José Martí, is a protein subunit vaccine containing COVID-derived proteins that trigger an immune response.[3] However, none of the clinical trial full results have been published. This candidate followed a previous one called CIGB-669 (MAMBISA).[4]

The vaccine is one of two Cuba-developed COVID-19 vaccines in Phase III trials.[5][6][7]

Clinical research

Phase I/II

In July 2020, CIGB-66 commenced phase I/II clinical trials.[8]

Phase III

The Phase III trial compares 3 doses of the vaccine administered at 0, 14 and 28 days against a placebo, with the primary outcome measuring the proportion of cases reported for each group 14 days after the third dose.

The trial was registered on 18 March 2021. The first dose was administered on 22 March and by April 4, the 48,000 participants had received their first dose,[9][10] and second doses started being administered from April 5.[11][12] Third doses have started being administered on 19 April[13][14][15] and on May 1, 97% of the original participants had received their 3 doses, the others 3% were lost in the process.

Intervention study

124,000 people aged 19 to 80 received 3 doses of the vaccine as part of an intervention study, with the primary outcome measuring the proportion of cases and deaths for the vaccinated compared to the unvaccinated population.[16]

A wider intervention study with the 1.7 million inhabitants of Havana is expected to start in May with the ABDALA and Soberana 2 vaccine.[17]

Efficacy

From May 3, the efficacy of the vaccine will start being evaluated.[18][19][20]

The “first evaluation of efficacy” can begin when there is 50 cases, then there is a second evaluation at 100 cases and a definitive efficacy can “finally be demonstrated” at 150 cases, Cuban Center for Genetic Engineering and Biotechnology director said.[21]

Production outside Cuba

Venezuela has claimed that it will manufacture the vaccine[22] but this claim has not yet materialised.[23] State-owned EspromedBIO will manufacture the vaccine but some “arrangements” are needed to start production.[24] In April, Nicolás Maduro said that a capacity of 2 Million doses per month is hoped to be reach by “August, September approximately”.[25

In June 2021, Vietnam’s Ministry of Health announced that negotiations were ongoing between Cuba and Vietnam for Abdala vaccine production. The Institute of Vaccines and Medical Biologicals (IVAC) was named as the focal point for receiving technology transfer.[26]

QazCovid-in

QazCovid-inVaccinePhase I/II/IIIThe QazCovid-in vaccine is an inactivated vaccine. Inactive viral vaccines are created by propagating viruses in cell culture (such as in Vero cells) and/or by inactivation using a chemical reagent (such as beta-propiolactone or formaldehyde). Upon vaccination, this allows the body to generate a diverse immune response against numerous viral antigens while having no threat of actually being infected because the virus is inactive.NEWS FEED December 31, 2020The Republic of Khazakstan’s QazCovid-in COVID19 vaccine enters phase 3 with an expected 3000 participants. August 28, 2020QazCovid-in, an inactive viral vaccine manufactured by Research Institute for Biological Safety Problems Republic of Kazakhstan enters Phase 1/2 clinical trials.ORGANIZATIONSResearch Institute for Biological Safety Problems, National Scientific Center for Phthisiopulmonology of the Republic of Kazakhstan, City polyclinic No. 4 of the UZO of Almaty, Clinic of the International Institute of Postgraduate Education, City Multidisciplinary Hospital of the Health Department of the Akimat of Zhambyl RegionCOUNTRIES INVOLVED TRIAL PARTICIPANTS

A new vaccine on the scene: Kazakhstan begins rollout of homegrown QazVac

The world’s approved COVID-19 vaccines have all come from large economies such as the U.S., China, the U.K., Russia, and India. Until today.

On Monday, Kazakhstan started rolling out its homegrown vaccine, now known as QazVac. Before a rebranding at the end of last month, it was called QazCovid-in, but the central Asian country’s government decided that name might be a turnoff for the public.

The vaccine was developed by Kazakhstan’s Research Institute for Biological Safety Problems, which claimed 96% efficacy in the second stage of clinical trials. The final phase is still ongoing, with a conclusion expected in July, but Kazakh health authorities decided it was fine to begin the rollout as long as the 3,000-participant Phase III trial was at least halfway finished.

This isn’t an adenovirus vector vaccine like those from Johnson & Johnson and AstraZeneca—though it does share their relatively mild refrigeration requirements—nor is it an mRNA-based jab like the BioNTech/Pfizer and Moderna vaccines. Instead, it uses an inactivated form of the SARS-CoV-2 virus itself, much like China’s CoronaVac and India’s Covaxin, which are both in use, and Valneva’s vaccine, which isn’t there yet. The QazVac regimen comprises two doses, to be administered three weeks apart.

‘Turn the tide’

Health Minister Alexei Tsoi was one of the first QazVac recipients on Monday morning. Tsoi was at the start of this month on the receiving end of a public dressing-down by President Kassym-Jomart Tokayev, who was furious about the sluggish start to the country’s inoculation campaign amid rising case numbers.

“You must turn the tide, otherwise a personnel decision that is going to be very disappointing for you will follow,” Tokayev told Tsoi. The vaccination campaign, which had previously focused on frontline workers, then reportedly sprang to life for others too in the oil-rich country.

Thus far, Kazakhstan’s vaccination drive has been powered by Russia’s Sputnik V, which has been produced locally for the past couple of months (Tokayev opted for the Russian shot, rather than waiting for QazVac). By late last week, just over 800,000 people had received their first dose. Kazakhstan has a population of 18.8 million people; the government plans to inoculate 2 million each month.

Tokayev tweeted Friday that domestic production would provide vaccine availability to all citizens. If so, that would be a remarkable turnaround—Almaty health officials said five weeks ago that the largest Kazakh city had run out of vaccines, and mass vaccination would not be realistic in the near future.

QazVac may have given Tokayev the opportunity to praise Kazakhstan’s scientific prowess, but production remains a bottleneck. The first batch to be distributed runs to only 50,000 doses, and the next tranche, to be produced in May, will be of the same volume.

Tsoi said Monday that the Kazakh government was talking to Turkish manufacturers about increasing production capacity.

QazCovid-in, commercially known as QazVac,[1][2] is a COVID-19 vaccine developed by the Research Institute for Biological Safety Problems in Kazakhstan.[3][4][5] QazCoVac-P is a second COVID-19 vaccine developed by the Kazakh Biosafety Research Institute and in clinical trials.[6]

Clinical research

QazVac is currently in Phase 3 (III) of the Clinical Trial, which is expected to be fully completed by 9 July 2021.[7][8] It is unclear when the first preliminary results will be published.[9][10]

The administration of the vaccine for the general population began at the end of April 2021.[11] The Research Institute Kunsulu Zakarya’s Director General’s justification is that the trial is almost 50% completed and “people who have received [the] vaccine feel well; there have been no side-effects and the effectiveness of the vaccine is high”.[12]

Production

The vaccine was first manufactured by Kazakhstan’s Research Institute of Biological Safety Problems. Production capacity has been capped at 50,000 doses per month.

Beginning in June 2021, the vaccine is slated[13] to be packaged in large bulk to be bottled in Turkey by a major Turkish company.[14][15] This will allow for a production capacity of 500,000-600,000 doses per month.[16] The contract is still being negotiated,[17] despite earlier claims that suggesting the deal had already been finalized.[18][19]

Vaccine innoculation

The first batch of 50,000 doses was delivered on 26 April 2021, and vaccination began shortly after.[20] In June 2021, the capacity will increase to 100,000 doses per month, regardless of the contract for bottling in Turkey.[21]

Authorization

COVIran Barakat

COVIran Barakat, is an inactivated virus vaccine developed by Shifa Pharmed Industrial Co in Iran.[501

https://en.trend.az/iran/society/3439812.html

BAKU, Azerbaijan, Jun. 14 2021

By Elnur Baghishov – Trend:

An emergency license was issued for the use of the Iranian-made “CovIran Barakat” vaccine against the coronavirus yesterday on June 13, the Iranian Minister of Health and Medical Education Saeed Namaki said, Trend reports citing IRNA.

He made the remark in an event dedicated to the launch of a number of health and medical facilities in Iran’s Markazi Province today on June 14.

Namaki said that moreover, a license for the using of the Iranian-made “Pastor” vaccine against the coronavirus will be issued next week.

“Also, the licenses for the using of Iranian-made “Razi” and “Fakhra” vaccines will be issued in the near future,” he added.

According to the minister, the Iranian population will be vaccinated fully by the end of autumn with the opportunities created in connection with the production of vaccines in Iran.

Reportedly, about 10 million people in Iran are planned to be vaccinated with the “CovIran Barakat’ vaccine next week. The production of “CovIran Barakat” vaccine in Iran is expected to reach 50 million doses per month by the end of the summer.

On June 14, 26 health and medical facilities were launched in Iran’s Markazi Province. A total of 1.45 trillion rials (about $34.5 million) has been spent on these facilities.

Iran continues to monitor the coronavirus situation in the country. According to recent reports from Iranian officials, over 3.03 million people have been infected, and 82,217 people have already died.

Meanwhile, over 2.66 million people have reportedly recovered from the disease.

The country continues to apply strict measures to contain further spread. Reportedly, the disease was brought to Iran by a businessman from Iran’s Qom city, who went on a business trip to China, despite official warnings. The man died later from the disease.

The Islamic Republic only announced its first infections and deaths from the coronavirus on Feb. 19.

The outbreak in the Chinese city of Wuhan – which is an international transport hub – began at a fish market in late December 2019.

The World Health Organization (WHO) on March 11 declared COVID-19 a pandemic. Some sources claim the coronavirus outbreak started as early as November 2019.

A total of 5.2 million people have been vaccinated in Iran so far. About 4.35 million people were vaccinated on the first stage, and 851,000 people were vaccinated on the second stage.

COVIran Barakat is a COVID-19 vaccine developed by Iranian state-owned Shifa Pharmed Industrial Group. It has successfully been tested on animals and has been approved by the Iran Food and Drug Administration for testing on humans.[1][2][3] Phase 2/3 (II/III) clinical trial began on 13 March 2021,[4] and the first participants were inoculated on March 29.[5] Finally, the vaccine consumption license was issued on June 13, 2021.[6] Around 650 people worked in 3 shifts around the clock to develop the vaccine.[7]

Dr. Minoo Mohraz has been selected as the lead of the “Corona vaccine project in Iran”.[8] Dr. Mohraz is an Iranian physician, scientist, and AIDS specialist. She is a Full Professor (Emeritus) of Infectious Diseases at Tehran University of Medical Sciences and head of the Iranian Centre for HIV/AIDS.[9] Dr. Mohraz has also served as within the World Health Organization as an expert on HIV/AIDS in Iran and the Eastern Mediterranean.[10]

This vaccine has been authorised for emergency use by the Iranian authorities. This makes it the first locally developed to be approved for emergency use in the Middle East.[11]

Technology

On 29 December 2020, human trials of Iran’s first domestic COVID-19 vaccine candidate were started. The mechanism of production of this vaccine is based on the inactivated vaccine. In other words, “it is made of a coronavirus that has been weakened or killed by chemicals, similar to how polio immunizations are made.”[12]

Development

Iran’s first domestic COVID-19 vaccine candidate was started

Tayyebeh Mokhber, the first volunteer who receives a shot of COVIran Barakat was the daughter of Mohammad Mokhber director of setad. Minister of Health Saeed Namaki and Vice President for Science and Technology Sorena Sattari participated at the ceremony of vaccine injection. According to reports, there are more than 65,000 Iranians volunteered to test the vaccine and 56 selected people took part in the first phase of human trials which last 45 to 60 days.[13] The initial phase of human-testing for this vaccine started with the injection of 56 volunteers who were at the age of 18-50.[14][15][16]

The second/third group of volunteers were also injected with the vaccine.[17][18] According to the head of the vaccine production team at the Setad, the results show that this vaccine also neutralizes the British mutated COVID-19 virus.[19][20][21]

In March 2021, the Executive Office of Imam Khomeini’s Order began a Phase II–III clinical trial of COVIran Barakat with 280 participants in cities including Tehran, Mashhad, Karaj, Esfahan, Shiraz. According to the allowance of medical equipment department, the second phase coincided with third phase.[22][23] The vaccine has reached its third phase of human-testing;[24] and the first injection(s) of the 3rd phase began 25 April 2021.[25]

As official in charge of manufacturing Iran Barakat vaccines, Mohammad Reza Salehi said, “some neighboring countries tend to enter the third phase of the clinical trial of the Iranian “COVIran Barakat””. They are reviewing recommendations to let them participate.[14]

According to Setad (the Executive Headquarters of Imam’s Directive), under the direct control of the Supreme Leader of Iran, “production of the vaccine developed by one of its companies, Shifa Pharmed, could reach 12 million doses per month, six months after a successful trial ends”.[26] On 15 March 2021, he stated that EIKO has already a capacity of three million doses per month and that by end of June the capacity will be 15-20 million doses per month.[27][28]

On 29 March 2021, the Tehran Times reported that a capacity of three million doses per month was achieved;[citation needed] and the production line of 25 million doses per month of Iran Koo vaccine was discharged on 26 April 2021.[29]

On 10 May 2021, the first product of mass production of the Iranian corona vaccine called “COVIran Barakat” was unveiled in phase one of the vaccine production factory associated with Execution of Imam Khomeini’s Order (EIKO). Therefore, 2 industrial lines have been set up. The first production line is prepared and the second line is being prepared. By the end of September (taking into account the capacity of three million doses of the first line), 20 million doses of Iran Barakat vaccine will be available in the month.[30]

Convidicea (Ad5-nCoV)

Recombinant vaccine (adenovirus type 5 vector)

Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector)

CanSino Biologics, china

see https://covid19.trackvaccines.org/vaccines/2/

AD5-nCOV, trade-named Convidecia, is a single-dose[1] viral vector vaccine for COVID-19 developed by CanSino Biologics. It conducted its Phase III trials in Argentina,[2] Chile,[3] Mexico,[4] Pakistan,[5] Russia,[6] and Saudi Arabia[7] with 40,000 participants.

In February 2021, global data from Phase III trials and 101 COVID cases showed that the vaccine had a 65.7% efficacy in preventing moderate symptoms of COVID-19, and 91% efficacy in preventing severe disease.[8] It has similar efficacy to Johnson & Johnson’s Ad26.COV2.S, another one-shot adenovirus vector vaccine with 66% efficacy in a global trial.[9][1] Convidecia is similar to other viral vector vaccines like AZD1222Gam-COVID-Vac, and Ad26.COV2.S.[10] Its single-dose regimen and normal refrigerator storage requirement (2°to 8 °C) could make it a favorable vaccine option for many countries.[9]

Convidecia is approved for use by some countries in Asia,[11][12][13] Europe,[14][15] and Latin America.[16][17][18] Production capacity for Ad5-NCov should reach 500 million doses in 2021. Manufacturing will take place in China,[19] Malaysia,[13] Mexico,[20] and Pakistan.[21]

Ad5-nCoV is a recombinant adenovirus type-5 vector (Ad5) vaccine currently being investigated for prophylaxis against SARS-CoV-2.1,2 It is being developed by CanSino Biologics Inc., in partnership with the Beijing Institute of Biotechnology, who in March 2020 announced the approval of a phase I clinical trial (ChiCTR2000030906)1 with an expected completion in December 2020. The study will evaluate antibody response in healthy patients between the ages of 18 and 60 who will receive one of three study doses, with follow-up taking place at weeks 2 and 4 and months 3 and 6 post-vaccination.2

  2. Antibody Society: COVID-19 Archives [Link]

Technology

Convidecia is a viral vector vaccine similar to AstraZeneca‘s AZD1222 and Gamaleya‘s Gam-COVID-Vac.[10] Ad5-nCOV can be stored in less extreme cold conditions compared to mRNA vaccines.[22][9]

Efficacy

In February 2021, data released from an interim analysis of Phase III trials with 30,000 participants and 101 COVID cases showed that globally, the vaccine had an efficacy of 65.7% at preventing moderate cases of COVID-19 and 90.98% efficacy at preventing severe cases. In the Pakistan trial subset, the vaccine had an efficacy of 74.8% at preventing symptomatic cases 100% for preventing severe disease.[8]

While the efficacy rates were lower than the Pfizer–BioNTech and Moderna vaccines, its single-dose regimen and normal refrigerator storage requirement (2 to 8 °C) could make it a favorable option for many countries. It has similar efficacy to Johnson & Johnson’s Ad26.COV2.S, another one-shot adenovirus vaccine found to be 66% effective in a global trial.[9][1]

Clinical trials

Phase I-II

In early 2020, Chen Wei led a joint team of the Institute of Biotechnology, the Academy of Military Medical Sciences and CanSino Biologics to develop AD5-nCOV. According to the Chinese state media, the team registered an experimental COVID-19 vaccine for Phase I trial in China on 17 March 2020 to test its safety. The trial was conducted on 108 healthy adults aged 18 to 60 in two medical facilities in WuhanHubei province.[23]

In April, Ad5-nCoV became the first COVID-19 vaccine candidate in the world to begin Phase II trials.[24] The Phase II trial results were published in the peer-reviewed journal The Lancet in August 2020, and noted neutralizing antibody and T cell responses based on statistical analyses of data involving 508 eligible participants.[25] In September, Zeng Guang, chief scientist of the Chinese Center for Disease Control and Prevention said the amount of COVID-19 antibodies in subjects from the Phase I trials remained high six months after the first shot. Zeng said the high levels of antibodies suggested the shots may provide immunity for an extended period of time, although Phase III results were still required.[26] On September 24, CanSino began Phase IIb trials on 481 participants to evaluate the safety and immunogenicity of Ad5-nCoV for children ages 6–17 and elderly individuals ages 56 and above.[27]

In August, China’s National Intellectual Property Administration issued the country’s first COVID-19 vaccine patent to CanSino.[28]

On 16 May 2020, Canadian Prime Minister Justin Trudeau announced Health Canada had approved Phase II trials to be conducted by the Canadian Center for Vaccinology (CCfV) on the COVID-19 vaccine produced by CanSino. Scott Halperin, director of the CCfV said the vaccine would not be the only one going into clinical trials in Canada, and any potential vaccine would not be publicly available until after Phase 3 is complete.[29][30] If the vaccine trials were successful, then the National Research Council would work with CanSino to produce and distribute the vaccine in Canada.[30] In August 2020, the National Research Council disclosed the vaccine had not been approved by Chinese customs to ship to Canada, after which the collaboration between CanSino and the Canadian Center for Vaccinology was abandoned.[31]

Nasal spray trials

In September, CanSino began a Phase I trial in China with 144 adults to determine the safety and immunogenicity of the vaccine to be administered as a nasal spray, in contrast with most COVID-19 vaccine candidates which require intramuscular injection.[32] On June 3, 2021, Chen Wei announced the expansion of clinical trials was approved by the NMPA, in the meantime, they are applying for Emergency Use Listing for the nasal spray.[33]

Phase III

In August, Saudi Arabia confirmed it would begin Phase III trials on 5,000 people for Ad5-nCoV in the cities of Riyadh, Dammam, and Mecca.[7]

In October, Mexico began Phase III trials on 15,000 volunteers.[34][4]

In September, Russia began Phase III trials on 500 volunteers,[35] which Petrovax later received approval from the government to expand to 8,000 more volunteers.[36][6]

In September, Pakistan began Phase III trials on 40,000 volunteers as part of a global multi-center study.[5] As of December, about 13,000 volunteers have participated in trials of Ad5-nCoV.[22]

In November, Chile began Phase III trials on 5,200 volunteers to be managed by University of La Frontera.[37][3]

In December, Argentina’s Fundación Huésped began Phase III trials in 11 health centers in the metropolitan area of Buenos Aires and Mar del Plata.[2]

Combination trials

In April 2021, a new trial was registered in Jiangsu involving one dose of Convidecia followed by a dose of ZF2001 28 or 56 days later using different technologies as a way to further boost efficacy.[38]

Manufacturing

In February, Chen Wei who lead the development of the vaccine, said annual production capacity for Ad5-NCov could reach 500 million doses in 2021.[19]

In February, Mexico received the first batch of active ingredients for Convidecia, which is being packaged in Querétaro by Drugmex.[20]

In Malaysia, final filling and packaging of the vaccine for distribution would be completed by Solution Biologics.[13]

In May, Pakistan began filling and finishing 3 million doses a month at the National Institute of Health, which would be branded as PakVac for domestic distribution.[39]

If the vaccine is approved in Russia, Petrovax said it would produce 10 million doses per month in 2021.[40]

EpiVacCorona (Russian: ЭпиВакКорона, tr. EpiVakKorona) is a peptide-based vaccine against COVID-19 developed by the VECTOR center of Virology.[1][2][3] It consists of three chemically synthesized peptides (short fragments of a viral spike protein) that are conjugated to a large carrier protein. This protein is a fusion product of a viral nucleocapsid protein and a bacterial MBP protein.The third phase of a clinical trial, which should show whether the vaccine is able to protect people from COVID-19 or not, was launched in November 2020 with more than three thousand participants.[2] It is assumed it will be completed in August 2021.[2] According to the vaccine developers, the peptides and the viral part of the chimeric protein should immunize people who received this vaccine against SARS-CoV-2 and trigger the production of protective antibodies. However, some experts in the field have expressed concerns about the selection of peptides for use as vaccine antigens.[3][4] In addition, there are also serious concerns about the vaccine immunogenicity data, which have fueled independent civic research efforts[5][6][7] and criticism by some experts.[3][8][4][9][10] Meanwhile, the EpiVacCorona has received vaccine emergency authorization in a form of government registration and is available for vaccination outside the clinical trials.[11] The vaccine delivered via intramuscular route and aluminum hydroxide serves as an immunological adjuvant.

Description[edit]

Origin of EpiVacCorona antigenes

Composition

The vaccine includes three chemically synthesized short fragments of the viral spike protein – peptides, which, according to the developers of EpiVacCorona represent the protein regions containing B-cell epitopes that should be recognized by the human immune system.

These peptides are represented by following amino acid sequences:

1) CRLFRKSNLKPFERDISTEIYQAGS, 2) CKEIDRLNEVAKNLNESLIDLQE, 3) CKNLNESLIDLQELGKYEQYIK.[1][12][13]

In the vaccine all peptides are conjugated to a carrier protein, which is an expression product of the chimeric gene. This chimeric gene was created by fusion of two genes originating from different organisms, namely a gene encoding a viral nucleocapsid protein and a gene encoding a bacterial maltose-binding protein (MBP). The fusion chimeric gene expressed in Escherichia coli. The sequence of the chimeric protein is available from the patent.[4] The genetic construct of the chimeric gene also includes a short genetic fragment encoding a polyhistidine-tag, which is used to purify the chimeric protein from E. coli lysate. After the purification, the protein is conjugated with three peptides in a way that only one variant of the peptide molecule is attached to each protein molecule. As a result, three types of conjugated molecules are created: chimeric protein with attached peptide number 1, the same protein with peptide number 2, and finally the same protein with peptide number 3. All three types of conjugated molecules are included in the vaccine.[citation needed]

EpiVacCorona: antigens origin and composition

Vaccine antigens and antibodies

According to the developers’ publications,[14][5][6] vaccine antigens are three peptides of the spike protein and a chimeric protein consisting of two parts (viral nucleocapsid protein and bacterial maltose-binding protein). In addition, the polyhistidine-tag – a short peptide that is introduced into a vaccine composition to purify a chimeric protein from a bacterial lysate – is also a vaccine antigen against which antibodies can form in those who have received the vaccine. A person vaccinated with EpiVacCorona can develop antibodies not only to the peptides of the spike protein, but also to other antigens present in the vaccine. According to Anna Popova who is a head of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare, it takes 42 days for those vaccinated with EpiVacCorona to develop immunity.[15]

Development

Immunogenic peptide screening in rabbits for EpiVacCorona design

Preclinical studies

The primary screening of peptides for the search for the most immunogenic ones was carried out in animals. The level of antibodies that was triggered by each tested peptide after administration to rabbits was measured. In the test, hemocyanin protein was used as a carrier protein for the studied peptides. Further, on six species of animals (mice, rats, rabbits, African green monkeys, rhesus monkeys, guinea pigs), the vaccine was shown to be harmless in terms of such parameters as general toxicity, allergic properties, and mutagenic activity. In four species of animals (hamsters, ferrets, African green monkeys, rhesus monkeys), specific activity was shown: immunogenicity and protective properties against SARS-CoV-2. The main results of preclinical studies are published in the “Bulletin of the Russian Academy of Medical Sciences”.[12][13]

Clinical studies

The studies development timeline was reported in Russian media in January 2021.[16] There are currently two clinical trials of EpiVacCorona registered in the ClinicalTrials.gov database.[17][18][2]

Phase I-II

The trial “Study of the Safety, Reactogenicity and Immunogenicity of “EpiVacCorona” Vaccine for the Prevention of COVID-19 (EpiVacCorona)”[18] was registered in clinical trial database with ClinicalTrials.gov identifier: NCT04780035. Another trial with the same title was registered with ClinicalTrials.gov Identifier: NCT04527575. Results of the trial that included data on 86 participants were published in Russian Journal of Infection and Immunity, indicating preliminary evidence of safety and an immune response.[1] The publication reports preliminary results of the first two phases of clinical trials of the vaccine in volunteers, of which 14 people aged 18-30 years participated in the first phase, and 86 volunteers aged 18-60 years in the second phase. It is claimed that antibodies were formed in 100% of the volunteers, and the vaccine is also claimed to be safe.[1]

EpiVacCorona Vaccine Development Timeline

Phase III

The third phase of a clinical trial, which should show whether the vaccine is able to protect people from COVID-19 or not, was launched in November 2020 with more than three thousand participants planned. It is expected to be completed in September 2021.[2] In the clinical trials database the phase III trial etitled “Study of the Tolerability, Safety, Immunogenicity and Preventive Efficacy of the EpiVacCorona Vaccine for the Prevention of COVID-19[2]” was registered only in March 2021 with ClinicalTrials.gov Identifier: NCT04780035. Phase 3-4 trial was registered in Russia at 18.11.2020 with 4991 participants planned.[19]

EpiVacCorona vaccine registration certificate

Authorization

 
  Full authorization  Emergency authorization

See also: List of COVID-19 vaccine authorizations § EpiVacCorona

The VECTOR has received vaccine emergency authorization in a form of government registration in October 2020.[21]

In Russia phase III clinical study is called post-registration study. Therefore, government registration of the vaccine means permission to perform phase III clinical research and public vaccination outside of clinical trials as well.[21] Since December 2020, the vaccine has been released for public vaccination in Russia.[22]

As of March 2021, Turkmenistan is the only foreign state to register EpiVacCorona with full authorization.[23][24]

Russia’s Chief Health Officer Anna Popova said: “In December 2020 the EpiVacCorona documents were presented to the World Health Organization, and we are expecting a decision from WHO.”[25] However, Deutsche Welle reports “As of March 1, the WHO had yet to receive an Expression of Interest (EOI) from EpiVacCorona’s developers, “VECTOR,” to enable WHO experts to evaluate their vaccine.”[26]

Export

The Deputy Director-General of the World Health Organization (WHO) Dr. Soumya Swaminathan during news conference in Geneva that took place in October 2020, told: “We will only be able to have a position on a vaccine when we see results of the phase III clinical trials.”[27] According to the center’s director Rinat Maksyutov, many government and non-government organizations want to test or be involved in the production of the vaccine.[28] As of March 30, Venezuela obtained 1000 doses of the Russian EpiVacCorona vaccine for a trial.[29] Venezuela also has reached a deal to purchase doses of the vaccine, as well as manufacture it locally, Vice President Delcy Rodriguez provided this information on June 4, 2021.[30] Turkmenistan expects to receive EpiVacCorona, as the vaccine has already been approved for use in that country.[31]

Controversy

Independent study of clinical trial participants

Ministry of Health’s response to a request from trial participants to perform independent antibody screening tests

English translation of Ministry of Health’s response to a request from trial participants to perform independent antibody screening tests.

At the start of the Phase III, trial participants and those vaccinated outside the trial began to form a community through the Telegram messenger network. On January 18, 2021, the members of the community turned to the Ministry of Health of the Russian Federation with an open letter, in which they stated that the production of antibodies after vaccination among them is much lower than declared by vaccine developers. Study participants claimed that antibodies were not found in more than 50% of those who documented their participation in the study, although only 25% of the participants should have had a placebo according to the study design. The trial participants also claimed that negative results were obtained using the a special ELISA test developed and recommended by VECTOR for EpiVacCorona detection.[5][6][4] More questions about the quality and protectiveness of antibodies induced by EpiVacCorona appeared along with the first results of a special antibody VECTOR’s test, when, with a positive special test, negative results of all other commercially available tests were otained: LIAISON SARS-CoV-2 S1 / S2 IgG – DiaSorin, IgM / IgG – Mindray, SARS-CoV-2 IgG – Abbott Architect, Anti-SARS-CoV-2 ELISA (IgG) – Euroimmun, Access SARS-CoV-2 IgG (RBD) – Beckman Coulter, “SARS-CoV-2-IgG-ELISA -BEST “-” Vector-Best “,” Anti-RBD IgG “- Gamaleya Research Center.[5][6][4][8] Clinical trial participants conducted their own antibody mini-study that was performed in independent Russian laboratory. The study participants asked Dr. Alexander Chepurnov, the former head of the infectious diseases department at VECTOR, who now works at another medical institute, to check neutralizing antibodies presence in their serum samples.[3] They also sent to Dr. Chepurnov control serum samples from former COVID-19 patients or people vaccinated with another Russian vaccine, Sputnik V, which is known to trigger the production of neutralizing antibodies.[32] All serum samples were blinded before antibody tests. On 23 March 2021, the participants reported the results of their mini-study in an open letter to the Ministry of Health of the Russian Federation.[6][7] According to the letter, even with the help of the VECTOR antibody detection system, antibodies were detected only in 70-75% of those vaccinated with EpiVacCorona. However, the level of antibodies was very low. Moreover, according to the letter, virus-neutralizing antibodies were not detected in the independent research Dr. Alexander Chepurnov laboratory at all.[3][6][7] The trial participants asked Ministry of Health in their open letter to perform independent study for the verification of their findings.[3][6][7] In addition, the letter reports 18 cases of COVID-19 cases as of March 22, 2021 among those who received the vaccine and became ill (sometimes severe) three weeks or later after the second dose of EpiVacCorona.[33][6][7] April 20, 2021 the study participants got a reply, with refusal of performing any additional verification antibody tests or investigation of sever COVID-19 cases among vaccinated individuals. The reply include the following text: “Considering that the listed immunobiological preparations (vaccines) for the prevention of COVID-19 are registered in the prescribed manner, their effectiveness and safety have been confirmed.”

Vaccine criticism by independent experts

Some independent experts criticized the vaccine design[3][4] and clinical data presentation in the publication.[8][9][10] The experts are saying that peptide selection is “crucial” for the innovative peptide approach, which VECTOR uses for EpiVacCorona design. However, some researchers are not convinced that the viral spike protein peptides selected for the vaccine are actually “visible” by human immune system.[3][4][34] They stated that these peptides do not overlap[35] with peptides that have been shown in several publications to contain human linear B cell epitopes in spike protein of SARS-CoV-2.[36][37][38][39][40] Moreover, the study was criticized for the lack of positive control of convalescent plasma samples in reports related to neutralizing antibody titers in vaccinated individuals.[1][10] The same study was also criticized for presence of detectable antibodies in negative controls samples that were not discussed by authors.[1][10] In addition, vaccine developers have been criticized for aggressively advertising their vaccine efficacy prior to the completion of phase III clinical trial. The most substantial criticism came from Dr. Konstantin Chumakov, who currently serves as the Associate Director for Research at the FDA Office of Vaccines Research and Review. Dr. Chumakov said: “I would not be in a hurry to call this peptide formulation a vaccine yet, because its effectiveness has not yet been proven…For the introduction of such a vaccine, the level of evidence must be much higher, and therefore the developers of EpiVacCorona, before launching their vaccine on the market, had to conduct clinical trials and prove that their vaccine actually protects against the disease. However, such tests were not carried out, which is absolutely unacceptable.”[41]

The title page of the “EpiVacCorona” patent with Anna’s Popova name among inventors

Conflict of interest

The vaccine design was protected by several already issued patents (see section above). In each patent one of its co-authors is a namesake of Anna Popova who is a head of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare. This patent authorship represents an issue as far as Anna Popova is a head of the Russian agency that is charged with overseeing vaccine safety and efficacy. As a co-author of these patents, she might have an interest in promoting the vaccine despite its shortcomings.
