India waited with bated breaths as the DCGI was to give its nod for COVID vaccine. The approval for two COVID vaccines came earlier this morning and both Covishield and Covaxin have been given the nod for emergency use. While the Covishield has shown 70.42% efficacy, the efficacy results for Covaxin are still not out. DCGI has however, given its approval to Covaxin also, given that the vaccine is safe for use. Congress MP Shashi Tharoor has now tweeted and asked Dr Harsh Vardhan to provide clarification on Covaxin. Shashi Tharoor even termed the approval 'premature' and added that in the meantime AstraZeneca should be used. Earlier today, Congress loyalist Jairam Ramesh also hit out after the vaccine approval was announced.
