India’s first indigenous vaccine for the highly infectious coronavirus, Covaxin, has been designed to be effective if a person takes two doses, Bharat Biotech clarified today. The Hyderabad-based pharmaceutical firm, in a statement, stressed that the “efficacy can be determined 14 days after the second dose”. The clarification came shortly after Haryana Health Minister Anil Vij, who took the vaccine shot in the third phase of vaccine trials, tested positive for Covid-19.
“Covaxin clinical trials are based on a 2-dose schedule, given 28 days apart. The vaccine efficacy will be determined 14 days post the 2nd dose,” the Hyderabad firm said in an official statement. One of the three Covid vaccine candidates being tested in India, Covaxin – in its third phase of trials- will be administered to “26,000 subjects across 25 sites”, the statement read.
“The phase 3 trials are double-blinded and randomised, where 50 per cent of subjects will receive the vaccine and 50 per cent of subjects will receive placebo,” the firm said.
Earlier administered a single trial dose of the vaccine, Anil Vij tweeted today: “I have been tested Corona positive. I am admitted in Civil Hospital Ambala Cantt. All those who have come in close contact to me are advised to get themselves tested for corona.”
