Union Health Minister Harsh Vardhan on Sunday cautioned that the ICMR's Sero survey report should not create a sense of complacency in people, as the Indian population is not even close to achieving herd immunity.

His warning, in the third episode of the 'Sunday Samvaad' weekly interaction he has been holding with his social media followers every Sunday for the last three weeks, comes on the day when the World Health Organisation (WHO) also advised against any attempts to achieve herd immunity or to hope that it will eventually save people.
