I was reading this study on the efficacy, safety, and lot-to-lot immunogenicity of BBV152 (aka Covaxin).
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.
