>Covaxin is the inactivated virus-based COVID-19 vaccine being developed with Bharat Biotech and Covishield is the Oxford-AstraZeneca vaccine being manufactured locally by the Serum Institute of India under that name.
>So inactivated vaccines tend to have lower immunogenicity on average (when we look back on past vaccines). I would like to think if Covaxin neutralizes it, the others would likely do so as well. We will definitely need data but this is very promising
