Third Covid-19 wave inevitable and we must be prepared

The third phase of the pandemic is inevitable given the high level of circulating virus, principal scientific advisor K Vijayaraghavan said on Wednesday, without giving a timeframe. While the country is still battling the devastating second wave, he said, ‘’we should prepare for the new waves.’’
“Previous infections and vaccines will cause adaptive pressure on the virus for new changes and we should be prepared scientifically,” Vijayraghavan said. He said it was gut wrenching to see what was happening.
