Congress leader Shashi Tharoor questions Covaxin's approval; says 'not assuring'

Congress's Shashi Tharoor has questioned the govt for approving the Bharat Biotech's Covaxin for emergency use authorisation which was still in its trails. In a tweet Tharoor said:

"Very pleased to hear there were no serious adverse consequences, Dr Harsh Varshan. But you are saying "it's more likely to work" & " it's likely to have similar protective efficacy reported for others" is not assuring. "Likely" can only be "certain" after Phase 3 clinal trials".

With this, a political spat has begun between the opposition and the Centre. Two vaccines, Covishield and Covaxin have been approved by the govt in India. Listen in!
