The Indian Council of Medical Research's (ICMR) fourth national serological survey has found that two-thirds of Indians above the age of six years had the COVID-19 antibodies. But that does not mean that we are safe yet. The study also found that 40 crore people are still susceptible to the COVID-19 virus. Here's everything you need to know about the survey.

What were the most important findings?
The survey found that two-thirds of India, including children till the age of six had antibodies. “In conclusion, two-thirds of the general population that is above the age of six years had SARS-CoV-2 infection. More importantly, a third of the population did not have any antibodies… 40 crore population of this country is still vulnerable,” DG, ICMR, Dr Balram Bhargava said at the press meet. “States/districts/areas without antibodies run the risk of infection waves,” he added.
The survey has also shown that sero-prevalence has increased over the different editions of the survey and currently stands at 67.6 per cent. This is not surprising because the sero-prevalence is supposed to rise. But the findings state that the ser-prevalance was similar in both rural and urban areas.
While more than 50 per cent of the children were seropositive, the sero-prevalence among children was 57.2 per cent in the 6-9 years age group and 61.6 per cent in the age group 10-17 years.
