Serum Institute of India CEO Adar Poonawalla has voluntarily taken a dose of Covishield to endorse the “safety and efficacy” of the vaccine. Pune-based Serum is the manufacturer of the vaccine developed by Oxford University and AstraZeneca.

Prime Minister Narendra Modi flagged off the nationwide vaccination drive on Saturday.

Poonawalla took to Twitter to share the video in which he is seen being injected with the Covishield vaccine. The vaccine is currently reserved for the healthcare staff and frontline workers.

“I wish India and Narendra Modiji great success in launching the world’s largest COVID-19 vaccination roll-out. It brings me great pride that Covishield is part of this historic effort and, to endorse its safety and efficacy, I join our health workers in taking the vaccine,” Poonawalla captioned the video on Twitter.

Earlier, PM Modi warned the Indian citizens against spreading or falling for rumours about the vaccines.

“The DCGI (Drug Controller General of India) gave approval after they were satisfied with the data of the two vaccines. So stay away from rumours. India’s vaccines are developed in a way keeping in mind the conditions of the country,” PM Modi said while addressing the nation via video conferencing.

“It is my request to you: don’t make the mistake of taking off the mask and not maintaining social distance after getting the first dose of vaccine because immunity develops only after the second dose. Normally, vaccines take years to develop. But now we have two Made-In-India vaccines. This is an evidence of India’s scientific progress and talent,” he added.
