Bharat Biotech on March 3 said that results of its Phase 3 clinical trials had shown that the interim clinical efficacy of ‘Covaxin’ is 81 per cent. The vaccine demonstrated 81 per cent interim efficacy “in preventing COVID-19 in those without prior infection after the second dose," the company said. Participants in the phase 3 trials were between 18-98 years of age, including 2,433 over the age of 60 & 4,500 with comorbidities, the company further said. Indian Council of Medical Research (ICMR), which backed the vaccine & jointly conducted the trials, said that the results had been evaluated by an independent data safety & monitoring board.
