  • March 3, 2021: Bharat Biotech announced interim findings from  the Phase 3 study testing the Company’s COVID-19 vaccine candidate, COVAXIN (also known as BBV152). This is an inactivated vaccine that requires two doses, separated by a 4-week period.

    • A total of 25,800 people took part in the study. All study participants were recruited in India. More information about the study can be in Table 1 on this website.
    • 43 people in the study developed laboratory-confirmed, symptomatic COVID-19 beginning 14 days after they received the second dose of the vaccine. Of these, 36 had received the placebo vaccine and 7 had received COVAXIN. Thus, the vaccine is estimated to reduce the risk of getting symptomatic COVID-19 by 80.6%.
