WASHINGTON (AP) — The top U.S. infectious diseases expert said Sunday “it is entirely conceivable, maybe likely” that Americans will need a booster dose of the COVID-19 vaccine in the coming months, but it is too soon for the government to recommend another shot.
Dr. Anthony Fauci, who is President Joe Biden’s chief medical adviser, said the Centers for Disease Control and Prevention and the Food and Drug Administration did the right thing last week by pushing back against drugmaker Pfizer’s assertion about a booster within 12 months. Hours after Pfizer’s statement Thursday that it would seek authorization for a third dose, the two agencies said they did not view the booster shots as necessary “at this time.”
Fauci said clinical studies and laboratory data have yet to fully bear out the need for a booster to the current two-shot Pfizer and Moderna vaccines or the one-shot Johnson & Johnson regimen.
“Right now, given the data and the information we have, we do not need to give people a third shot,” he said. “That doesn’t mean we stop there. … There are studies being done now ongoing as we speak about looking at the feasibility about if and when we should be boosting people.”
He said it was quite possible in the coming months “as data evolves” that the government may urge a booster based on such factors as age and underlying medical conditions. “Certainly it is entirely conceivable, maybe likely at some time, we will need a boost,″ Fauci said.
Currently only about 48% of the U.S. population is fully vaccinated. Some parts of the country have far lower immunization rates, and in those places the delta variant is surging. Last week, Dr. Rochelle Walensky, the CDC director, said that’s leading to “two truths” — highly immunized swaths of America are getting back to normal while hospitalizations are rising in other places.
