“I worry that vaccines are going to be sold like magic powder that we sprinkle across the land and make the virus go away,” Paul Offit, MD, said at the virtual American Academy of Pediatrics (AAP) 2020 National Conference. “That’s not true.”
Even after effective vaccines for SARS-CoV-2 are in widespread use, wearing masks will still be advisable to prevent COVID-19, according to Offit, director of the Vaccine Education Center and an attending physician in the Division of Infectious Diseases at Children’s Hospital of Philadelphia.
“I think we can get a vaccine that’s 75% to 80% effective at preventing mild to moderate disease, but that means 1 of every 4 people can still get moderate to severe disease,” Offit continued.
And that’s if there is high uptake of the vaccine, which may not be the case.
