Attempts to reach herd immunity naturally ‘dangerous’: WHO

Vastavam web: Attempts to reach herd immunity naturally would be dangerous and fraught with scores of deaths, while vaccination is a safer and more effective path, Maria van Kerkhove, the COVID-19 technical lead at the World Health Organization (WHO), said on Thursday. “What we are working towards … is to have a safe and effective vaccine that can provide protection to a large proportion of the population so the virus doesn’t have an opportunity to transmit. At least two-thirds of a population needs to develop the immunity for it to matter, and that, in turn, needs the vaccine to happen safely and effectively, according to the health official.
