Americans who are fully vaccinated against COVID-19 do not need a booster shot at this time, the Food and Drug Administration and the Centers for Disease Control and Prevention said in a joint statement Thursday.
The news comes just hours after reports that Pfizer plans to request authorization to give people a third injection of its coronavirus vaccine amid the rise in more transmissible coronavirus variants across the country. The company, along with vaccine co-developer BioNTech, said a third injection could significantly “boost” antibodies that protect people vaccinated against COVID-19.
The FDA and CDC, however, said that those who are fully vaccinated are, so far, well protected against COVID-19 and its variants. All vaccines available in the U.S. provide meaningful protection against coronavirus, including the emerging delta strain.
“People who are fully vaccinated are protected from serious illness and death, even from variants currently circulating in the country like Delta,” the agencies said in a joint statement. “People who are not vaccinated are still at risk. Virtually all deaths from COVID-19 occur among those who are not vaccinated. ”
“Americans who have been fully vaccinated do not need a booster shot at this time,” they continued, adding that researchers are testing whether a booster dose might be necessary in the future.
“We are prepared for booster doses as long as science shows they are necessary.”
Pfizer and BioNTech also said Thursday that they will begin developing a version of a COVID-19 vaccine that targets the delta variant and that they hope to launch clinical trials next month.
Public health officials have continued to urge Americans to get vaccinated against COVID-19, particularly since the delta strain of the coronavirus is now estimated to be the dominant variant in the US.Number of new infections due to the high number of new infections. delta variant transmissibility.

Those deaths, that pain, can be prevented. Get vaccinated. “
