The ICMR and the Union Health Ministry on Thursday made the findings of the third sero-survey public, highlighting the necessity of vaccination as a large proportion of the population was still vulnerable to the virus.
The latest serosurvey, conducted between December 17 last year and January 8, was carried out in the same 700 villages and wards in 70 districts of 21 states which were selected during the previous two sero-surveys held in May-June and August-September last year, respectively.
Here are 10 key takeaways from the latest survey:
