6 Key Findings of COVAXIN The Lancet Peer-Review

    COVAXIN The Lancet Peer-Review is out now which re-affirms its efficacy and safety. Bharat Biotech, a global leader in vaccine development and innovation, announced ( on Friday today morning) that the safety and efficacy analysis data from Phase III clinical trials of COVAXIN® is peer reviewed and published in The Lancet. This study follows 10 other peer-reviews published in leading scientific journals.

    The Lancet peer-review confirms the efficacy analysis which demonstrates COVAXIN® to be effective against COVID-19. COVAXIN®is the only COVID-19 vaccine to have demonstrated efficacy data from phase III clinical trials against the delta variant at 65.2%.

    COVAXIN The Lancet Peer-Review Publication – 6 Key Findings

    1. Efficacy analysis demonstrates COVAXIN® to be 77.8% effective against symptomatic COVID-19, through evaluation of 130 confirmed cases, with 24 observed in the vaccine group versus 106 in the placebo group
    2. Efficacy analysis demonstrates COVAXIN® to be 93.4% effective against severe symptomatic COVID-19
    3. Safety analysis demonstrates adverse events reported were similar to placebo, with 12% of subjects experiencing commonly known side effects and less than 0.5% of subjects experiencing serious adverse events
    4. Efficacy data demonstrates 63.6% protection against asymptomatic COVID-19
    5. Efficacy data demonstrates 65.2% protection against the SARS-CoV-2, B.1.617.2 Delta
    6. Efficacy data demonstrates 70.8% protection against all variants of SARS-CoV-2 virus

    COVAXIN® was developed under a partnership with the Indian Council of Medical Research and the National Institute of Virology, with Bharat Biotech receiving the SARS-COV-2 strains through this collaboration.

    Bharat Biotech had established an ongoing collaboration with ViroVax since 2019, through the Indo-U.S. Vaccine Action Program, to develop and evaluate IMDG (Alhydroxiquim-II), a novel TLR7/8 agonist molecule, which is formulated as part of the adjuvant in COVAXIN®. The Adjuvant Program of the U.S. National Institute of Allergy and Infectious Diseases (NIAID) has supported ViroVax since 2009.

    COVAXIN – the lancet peer-review – reaffirms India’s COVAXIN effectiveness against COVID-19

    Dr. Krishna Ella, CMD of Bharat Biotech said,

    “The peer-review of COVAXIN® phase III clinical trial data in The Lancet, an authoritative voice in global medicine validates our commitment to data transparency and meeting the stringent peer-review standards of world leading medical journals.”

    COVAXIN data product development and clinical trial data published in 10 peer-review journals

    The data from our product development and clinical trials have been published in 10 peer-reviewed journals, making COVAXIN® one of the most highly published COVID-19 vaccines in the world.

    This accomplishment reflects the undeterred commitment by my team members at Bharat Biotech, our public partners, Indian Council of Medical Research, National Institute of Virology, and the trust imposed by our trial participants who made this happen.”

    The phase 3 trial Efficacy and Safety Study involving 25,800 volunteers across 25 sites in India is India’s largest ever clinical trial conducted for a Covid-19 vaccine.

    COVAXIN® was well tolerated and the Data Safety Monitoring Board has not reported any safety concerns related to the vaccine. The overall rate of adverse events observed in COVAXIN® was lower than that seen in Covid-19 vaccines. The safety profile of COVAXIN® is now well established based on inactivated vaccines technology, and in large part due to the extensive 25-year safety track record of Bharat Biotech’s vero cell manufacturing platform.

    Dr. Balram Bhargava, Director General, Indian Council of Medical Research (ICMR) said,

    “Following successful isolation of the SARS-CoV-2 virus at ICMR -National Institute of Virology (NIV), Pune, ICMR and Bharat Biotech International Ltd (BBIL) embarked upon one of the most successful public-private partnership to develop the virus isolate into an effective COVID-19 vaccine. I am delighted to see that the phase III efficacy data has also been published in THE LANCET, one of the most reputed journals worldwide. This itself speaks high about the strong position of COVAXIN® amongst other global front-runners COVID-19 vaccines. The bench to bedside journey of COVAXIN® in less than 10 months showcases the immense strength of “Atmanirbhar Bharat” along with the Indian academia and industry in fighting against the odds and carving a niche in the global community.”

    Recently, the World Health Organization granted emergency use listing to COVAXIN® enabling countries to expedite their regulatory approval to import and administer doses. It has also received emergency use authorizations in several countries with applications in process in more than 50 countries worldwide. Bharat Biotech has partnered with Ocugen to obtain approvals for COVAXIN® in the United States and Canada.

    COVAXIN – More than 150 Million doses manufactured, and supplied

    With more than 150 million doses manufactured, supplied, and with an excellent safety and efficacy profile, COVAXIN®is a major contributor to the global fight against the COVID-19 pandemic.

    COVAXIN®is currently being evaluated in controlled clinical trials in children 2-18 years of age, with results available during Q4 2021.

    Bharat Biotech is poised to achieve its goal of an annualized capacity of ~1.0 billion doses of COVAXIN® by the end of 2021.
