Though the number of Covid-19 cases are under control, the BMC wants to conduct the next serosurvey in February, to analyse the situation and act accordingly. The schedule also has a relevance of completion of one year of the anti-Coronavirus vaccination.

After a novel Coronavirus infection or vaccination against it, the human body produces antibodies against the virus. The serosurvey conducted in August had revealed that about 87 per cent of people had antibodies. The results had shown that antibodies were present in 90 per cent fully vaccinated people, and 80 per cent of those who hadn't been immunised.  It means most of the people had antibodies and the chance of a third Covid-19 wave could be less.
