According to analysis by Professor Gyaneshwer Chaubey of Department of Zoology in Banaras Hindu University, there is no possibility of third wave of Covid in coming months as he claims that 70-75 per cent people still have antibodies that'll last next three months. “We're doing regular surveillance. Last time too we saw that the 2nd wave came after seropositivity reached below 10 per cent. So this time too we're doing surveillance every month, antibodies of particular people are being checked,” he added.
