A day after the US Food and Drug Administration (FDA) denied approval for emergency use of Covaxin, actors Vir Das and Konkona Sen Sharma have tweeted their concern, as they took the first shot of Covaxin a few weeks ago.

Vir Das tweeted, "Took the first available vaccine which was #covaxin by @BharatBiotech @SuchitraElla and now it appears both their FDA approval and WHO approval will take a lot longer than anticipated. Their data is still due. Many like me travel for work. We would like an explanation, please. [sic]"
