The fifth blood serum survey that tests for antibodies, known as the serological survey conducted between August and early September, included 8,674 adults, nearly 65% of whom were vaccinated.
The survey also found that more women had COVID-19 antibodies compared to their male counterparts at 88.29% versus 85.07%.
Seroprevalence was significantly higher in people who received the first or both doses of the COVID-19 vaccine compared to their unvaccinated counterparts, the Brihanmumbai Municipal Corporation (BMC) survey noted.
“As the seroprevalence among those who are vaccinated is much higher than the unvaccinated counterparts, it is essential to strengthen the ongoing COVID-19 vaccination program,” the report said.
India’s overcrowded financial hub, Mumbai, has won praise this year for dealing with the second wave of the pandemic better than any other metropolis in the country.
The report’s conclusion comes at a time when concerns about the emergence of a third wave remain. India reported 34,403 new cases of COVID-19 on Friday across the country.
