The government recently announced the findings of the fourth national sero-survey and said that two-thirds of the population – aged above six years – has SARS-CoV-2 antibodies but stressed that around 40 crore people are still vulnerable to the infection. State heterogeneity 'indicates the possibility of future waves of infection,' the government warned, adding that people should travel only if fully vaccinated.
