SII manufactured Oxford University-AstraZeneca's vaccine Covishield, while Bharat Biotech developed the other vaccine Covaxin that is being administered in the inoculation drive.

Union Health Minister Harsh Vardhan described Covid-19 vaccines as "Sanjivani" in the fight against the infectious disease as he urged people not to pay heed to hearsay and instead believe in experts and scientists.
