Sero survey: 70% in Kerala may have acquired natural immunity against COVID-19

When the State was organising mass vaccination drives to protect the community from the ill effects of COVID-19 infection, natural infection had already penetrated to 70% of the State’s population.
The third round of sero survey conducted by Kerala across all districts to assess the levels of COVID-19 antibodies in the population has reported that post second wave, at least 70 % of the population may have achieved natural immunity against COVID-19.
While the overall sero prevalence in the adults in the community is estimated at 82.61% (either Anti -spike IgG antibody or Anti-nucleocapsid IgG antibody), the Health department’s report states that the proportion of sero positivity in those who were unvaccinated was 70%.
This essentially means that even when the State was organising mass vaccination drives to protect the community from the ill effects of COVID-19 infection, natural infection had already penetrated to 70% of the State’s population.
