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.”

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.
