He doesn't sound too confident:

Spoiler:

"A degree of protection", doesn't fully stop the Infection.

yes but there is no vaccine that can guarantee for 100% protection . success rate is 78% . still in development .

That's good news for India ! I can't even imagine the challenge it should be to provide vaccines for such a huge country.
Although I'm personally not too worried about vaccines efficacy on variants.
Yeah some are much less efficient than others on some variants, but still (much !) better than nothing. And mostly, I believe most vaccines (but even more RNA vaccines) can be adapted in a not-too-long time for newest variants.

all vaccine are RNA only , because corno is rna type .best thing is covaxin contain dead corona virus which enter our body than our anti body will surround weak cornona and fight . after taking vaccine everyone will get fever because anti bodies will fight , but USA vaacine are different they block corona spike which is called protien , anti bodies stick on protien than corona cannot enter in lung tissue and there corona keep roming and will died.

Just got my second vaccine of Pfizer today. When people starting talking of the various strains, it seems like there's less information on which vaccines are more efficient overall.

pfizer has some disadvantages like these vaccine can be stored in very high cold temperature. .. so difficult to export import ... challenge will be there...

How many time vaccine will be need to take ?
