"People are surprised that only three vaccines have been made available in India: Covishield, Covaxin and Sputnik Of the three, you can write off Sputnik because only a small quantity was imported in the initial days," Congress veteran Chidambaram had tweeted on December 27, 2021. "We are left with 2 vaccines thanks to the PROTECTIONIST policy of the Modi Government Pfizer, Moderna and other WHO-approved vaccines are kept out of India on one pretext or other Which is why we don't have enough vaccines to administer 2 doses to the 94 crore adult population."
