Shortly after taking office in January, President Biden expressed confidence that increased vaccine access for Americans over the coming months will lead to herd immunity by summer. .
When reporters asked the president when anyone who wants a vaccine might be able to get one, Biden said: "I think we’ll be able to do that this spring." And looking forward, he added that "I feel confident by summer we’ll be well on our way towards herd immunity and increasing access." .
"Herd immunity" means that enough people have immunity, either from vaccination or from a past infection, to stop the uncontrolled spread of a disease.
However, herd immunity doesn’t make any one person immune, and outbreaks can still flare up
Despite the president’s "herd immunity" predictions in January, COVID cases – fueled by the deadlier and more contagious delta variant of the virus – remain at all-time highs.
