$OCGN Do yourselves a favor and just educate yourselves on the history of vaccines and you will be astounded. Why? For anyone thinking these early vaccine entrants have squashed tge need for any new vaccines, read up on virologist Albert Sabin. Cliifs Notes...In the late 50s he developed a live polio vaccine but the U.S. was not interested bc most of the population had already received another vaccine (intra-muscular). However, 100 million Russians needed abd did receive it. Guess what? The results were so overwhlemingly positive, guess again who approved it? Yep, good ole late-to-the-party USA. Vaccine diplomacy will be what ultimately makes Covaxin the gold standard, IMO. But don't trust me...Google is your friend.
