Council of Scientific and Industrial Research (CSIR) Director-General Shekhar C Mande on Feb.28 warned that the Covid-19 crisis was far from being over and allowing the third wave by lowering our guard is fraught with grave consequences.

Mande was speaking on India's response to Covid-19 from S & T perspective at a virtual National Science Day Lectures. The expert clarified that India is nowhere near achieving herd immunity and as such people should continue to wear masks and maintain social distancing and hand hygiene to stay away from getting infected by the virus.

Cautioning the people and the scientific community against allowing complacency to set in, he warned that a third wave would precipitate a far more dangerous situation than the challenge the country had faced so far. Mande expressed the hope that the Covid-19 vaccines would be effective against the coronavirus variants.

The evidence is not very strong that the vaccines would not work against the mutated virus. "We would like to believe that the vaccines are effective" against the variants as the vaccines worked against the entire part of the virus while the mutation took place on a part of the virus, he explained.

The prevalence of Covid-19 cases had come down not because of herd immunity, but because of other reasons, including wearing masks and people remaining outdoors during the winter. The fact that the virus remained suspended in the air in closed areas and it lost its potency in open areas helped a great deal in controlling the spread during the winter, the expert said.
