Herd Immunity in Sight for India’s Capital?

The latest antibody testing data conducted in Delhi, India suggests that the nation's capital may be very close to attaining herd immunity against COVID-19. The Delhi government has been regularly conducting antibody tests since August 2020 to assess the spread of the virus in the capital region. In the fifth and the largest survey so far, more than 28,000 samples were tested across 11 districts in Delhi between Jan. 11 and Jan. 22. Preliminary results show that more than 60% of residents in one district in Delhi had antibodies against the coronavirus. The antibody rate in other districts more than 50%. If these findings hold true, it would imply that half of the city's 20 million people has been exposed to the virus and recovered.
