It, however, added that despite this reduction, neutralizing titre levels with B.!.617 remain above levels expected to be protective.

“No difference in neutralization between B.1.1.7 (first found in the UK) and vaccine strain (D614G) was observed,” Bharat Biotech added.

These findings are from a study conducted in collaboration with the National Institute of Virology – India Council of Medical Research.

It is to be mentioned that, Covaxin is one of the three Covid-19 vaccines that are currently available in the country.
