CCMB chief says India develops herd immunity; BF.7 variant may not be as serious as in China

The severity of BF.7 variant of coronavirus in India may not be as serious as it is currently prevailing in China as Indian have already developed herd immunity a top official of CSIR-Centre for Cellular and Molecular Biology (CCMB) here said.

Vinay K Nandicoori, Director CCMB, stressing the need to follow Covid appropriate behaviour, said there is always a concern that all these variants have the ability to escape the immunity and can infect people who are vaccinated and even sometimes infected with the previous variants of Omicron.

The severity of the infection is not as much as they used to be with Delta. That's because of the fact that we do have herd immunity to an extent. Actually we have herd immunity because we are exposed to the other viruses, he told PTI.

We (India) have seen the Delta wave which is a big one. Then we have got vaccination done. And then the Omicron wave came and we continued booster doses. We are different in many ways. What is happening in China may not happen in India because of that, he further said.

It is actually that (the zero Covid policy that China is followed) and also the fact is in China, not many people really went for the vaccine as it has happened in India all the older population is vaccinated and sometimes even sometimes booster dose has been given to older population or susceptible population, he said.

Maintaining that at this point it cannot be asserted that there may or may not be a wave in India, Nandicoori said as of now it does not seem to be that alarming that a wave is coming right away.
