Recent reports have suggested that herd immunity may be achieved when as little as 50% of the population is immune. Herd immunity occurs when enough of the population is immune to the coronavirus, either via exposure or vaccine, for transmission to wane.
That’s a welcome projection in light of earlier estimates that at least 70% of the population would need immunity before we’d be at “herd” level.
But these estimates are largely irrelevant and a distraction from the tools experts know work in combatting the coronavirus’s spread, World Health Organisation officials said during a media briefing Monday.
