I was reading this study on the efficacy, safety, and lot-to-lot immunogenicity of BBV152 (aka Covaxin). Covaxin is an inactivated virus-based vaccine similar to the polio vaccine. I am quite indifferent on this particular vaccine; frankly, beyond this study, I do not know anything about it. The study, as can be expected, makes the vaccine look promising, but it is not particularly useful to read pharmaceutical studies on the surface these days.
Do we know yet whether original Covaxin or the Oxford-AstraZeneca Covishield was most responsible for the development of Delta variant in India, before kindly sharing it's mutants with the world?

Covaxin was late to the party as far as vaccines go, so must have been AZ.
