Covaxin COVID-19 Vaccine (BBV152) Description
Bharat Biotech's Covaxin (BBV152) is an inactivated COVID-19 vaccine that uses adjuvant Alhydroxiquim-II to boost immune response longer-lasting immunity. The Indian Council of Medical Research created the Covaxin (BBV152) vaccine. Inactivated vaccines do not replicate and are unlikely to revert and cause pathological effects, says the U.S. CDC.
The Covaxin vaccine is a whole virion inactivated SARS-CoV-2 vaccine, which develops from a well-known SARS-CoV-2 strain (NIV-2020-770) and a Vero cell platform (CCL-81) with adjuncts of either aluminum hydroxide gel (Algel) or a novel TLR7/8 agonist adsorbed gel. The virus strain is soaked in beta-propiolactone, an organic compound that deactivates them by binding to their genes.
The SARS-CoV-2 betacoronavirus strain was isolated from an asymptomatic COVID-19 patient at India's National Institute of Virology.
The vaccine's adjuvant was developed with funding from the U.S. National Institutes of Health has contributed to the success of the highly efficacious COVAXIN COVID-19 vaccine. The TLR7/8 adjuvant formulation specifically induced significant Th1 biased antibody responses and increased SARS-CoV-2 lymphocyte responses.
COVAXIN (BBV152) contains six µg of whole-virion inactivated SARS-CoV-2 antigen (Strain: NIV-2020-770), and the other inactive ingredients such as aluminum hydroxide gel (250 µg), TLR 7/8 agonist (imidazoquinolinone) 15 µg, 2-phenoxyethanol 2.5 mg, and phosphate ® buffer saline up to 0.5 ml. The components of the Covaxin vaccine include BBV152A, BBV152B, and BBV152C.
On March 8, 2021, The Lancet published a study 'Safety and immunogenicity of an inactivated SARS-CoV-2 vaccine, BBV152: interim results from a double-blind, randomized, multicentre, phase 2 trial, and 3-month follow-up of a double-blind, randomized phase 1 trial.' This study concluded by saying, 'In the phase 1 trial, BBV152 induced high neutralizing antibody responses that remained elevated in all participants at three months after the second vaccination. In the phase 2 trial, BBV152 showed better reactogenicity and safety outcomes and enhanced humoral and cell-mediated immune responses compared with the phase 1 trial. The 6 μg with Algel-IMDG formulation has been selected for the phase 3 efficacy trial.'
On April 21, 2021, Bharat Biotech announced phase 3 interim analysis results of COVAXIN. The second interim analysis results in a point estimate of vaccine efficacy of 78% (95%CI: 61-88) against mild, moderate, and severe COVID-19 disease. The efficacy against severe COVID-19 disease was 100% (95%CI: 60-100), impacting reduction in hospitalizations. The efficacy against asymptomatic COVID-19 infection was 70%, suggesting decreased transmission in COVAXIN® recipients.
ANI reported on May 16, 2021, Covaxin (BBV152) was found effective against coronavirus strains found in India and the U.K. These findings are from a study conducted in collaboration with the India Council of Medical Research. "No difference in neutralization between B.1.1.7 (U.K.) and vaccine strain (D614G) was observed," Bharat Biotech added.
On June 4, 2021, a non-peer-reviewed study found 'Covaxin vaccinated healthcare workers could produce a high immune response in up to 95% of recipients and prevent serious disease in those infected after immunization.'
Dr. Balram Bhargava, Secretary Department of Health Research & Director General Indian Council of Medical Research, said in a press statement issued on July 3, 2021, "I am delighted to note that COVAXIN®, developed by ICMR and BBIL under an effective public-private partnership, has demonstrated an overall efficacy of 77.8% in India's largest COVID phase 3 clinical trial thus far. Our scientists at ICMR and BBIL have worked tirelessly to deliver a truly effective vaccine of the highest international standards. COVAXIN® will benefit the Indian citizens and immensely contribute to protecting the global community against the deadly SARS-CoV-2 virus. I am also pleased to see that COVAXIN® works well against all variant strains of SARS-CoV-2. The successful development of COVAXIN® has consolidated the position of Indian academia and industry in the global arena."
As of April 2021, Covaxin cost in India is about 295 rupees (US$ 3.97).
GAVI confirmed on July 6, 2021, Bharat Biotech insisted the vaccine was safe and provided a robust immune response. Supportive Phase 3 trial non-peer-reviewed data was published on July 2, 2021.

Covaxin COVID-19 Vaccine (BBV152) Indication
Indian Council of Medical Research announced on April 22, 2021, Covaxin offers protection against various SARS-CoV-2 mutations. The Covaxin vaccine is indicated to prevent the SARS-CoV-2 beta coronavirus infection that causes COVID-19 disease in humans. The company says that the National Institute of Virology analysis indicates that vaccine-induced antibodies can neutralize the U.K. variant strains and other heterologous strains.
The National Institute of Virology analysis indicates that vaccine-induced antibodies can neutralize the U.K. variant strains and other heterologous strains.
Individuals with HIV infection or other immunocompromising conditions or who take immunosuppressive medications or therapies might be at increased risk for severe COVID-19. However, data is NOT currently available to establish vaccine safety and efficacy in these groups. In addition, individuals with immunosuppression may not generate a full immune response to COVID-19. There is no scientific information yet available on the appropriateness of COVAXIN along with other vaccines.

On July 2, 2021, a non-peer-reviewed study found the 'BBV152 vaccine was well tolerated with no clinically or statistically significant differences in the distributions of solicited, unsolicited, or serious adverse events between vaccine and placebo groups.' Adverse events reported were similar to placebo, with 12.4% of subjects experiencing commonly known side effects and less than 0.5% felt serious adverse events.
Covaxin - Ocugen Agreement
Ocugen, Inc., a Pennsylvania-based biopharmaceutical company, and India-based Bharat Biotech announced on February 2, 2021, has entered into a definitive agreement to co-develop, supply, and commercialize Bharat Biotech's COVAXIN United States market.

Combining these data with the only Delta-variant results from a controlled Phase 3 clinical trial, evidence continues to support a favorable benefit-risk profile for COVAXIN," said Dr. Bruce Forrest, Acting Chief Medical Officer and a member of the vaccine scientific advisory board of Ocugen, in a press statement issued on July 2, 2021.
On July 15, 2021, Ocugen confirmed it had initiated a rolling submission to Health Canada for Covaxin. Soon after, the Company announced the completion of its regulatory submission to Health Canada for COVAXIN™, which was accepted under the Minister of Health's Interim Order Respecting the Importation, Sale, and Advertising of Drugs for Use in Relation to COVID-19 and transitioned to a New Drug Submission for COVID-19. The submission was conducted through the Company's new affiliate, Vaccigen, Ltd., and the review process has begun in Canada.
Ocugen issued a press statement on August 6, 2021, which included the following disclosures: Discussions with the U.S. FDA are ongoing, and the Company is still proceeding with a strategy focused on the agency's requested Biologics License Application pathway and determining what data requirements and U.S.-based clinical trials will be required to support such submission.
