NEW DELHI : While a large number of people now have immunity against coronavirus due to previous infections or vaccination, a guarded approach is needed in terms of implementing restrictive measures to avoid a second wave-like crisis, experts said.
Dr Yudhyavir Singh, who has been managing the COVID-19 ICU at AIIMS New Delhi, said it is important to lift a few restrictions to resume economic activities when cases are low. "However, one should not lower their guard … Adopt a guarded approach in terms of following COVID-19-appropriate behaviour and implementing restrictive measures," he said.
Dr Singh added that Delhi may have already achieved herd immunity, considering the massive number of cases seen during the second wave.
