CDC Walks Back Director’s Comments on Vaccines Preventing Infection
After pushback from scientists, the CDC has walked back a statement by its director and stressed that “the evidence isn’t clear whether [vaccinated people] can spread the virus to others.” Earlier this week, Dr. Rochelle Walensky said that data “suggests that vaccinated people do not carry the virus, don’t get sick.” Many observers took that as confirmation that a jab grants full protection from transmission and infection. In a statement the next day to The New York Times, the CDC said: “It’s possible that some people who are fully vaccinated could get Covid-19.” Dr. Paul Duprex, a vaccine expert at the University of Pittsburgh, agreed. “We’re stopping symptoms, we’re keeping people out of hospitals. But we’re not making them completely resistant to an infection,” he said.
While the vaccine’s efficacy in preventing infection is very high, John Moore, a virologist based in New York, told the Times: “Vaccinated people should not be throwing away their masks at this point... This pandemic is not over.”
