If the US doesn’t reach 80% immunity, the nation could see another winter surge of coronavirus, says vaccine expert
As health experts point to the challenges the nation faces in reaching herd immunity, some are warning of the danger of not getting there: another surge of coronavirus this winter.
Vaccine expert Dr. Paul Offit reckons that 80% of the population needs to be immune to the virus in order to prevent that scenario.
“The proof will be in the pudding next winter,” Offit told CNN’s Jake Tapper. “If we don’t get there to 80%, then I think you’ll see another surge of this virus next winter.”
