The US needs to reach 80% herd or community immunity or the nation could be in store for another surge in the coronavirus pandemic this winter, vaccine expert Dr. Paul Offit said Tuesday.
“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.”
Offit is director of the Vaccine Education Center at Children's Hospital of Philadelphia and a member of the US Food and Drug Administration's vaccine advisory committee.
He went on to say that the 80% population immunity could be achieved through a combination of both vaccination and immunity from natural infection.
President Biden announced Tuesday a goal to administer at least one dose of Covid-19 vaccine to 70% of the nation’s adult population by July 4.
