https://ift.tt/2kmUBVA. health authorities said Thursday that 16- and 17-year-olds should get a booster dose of Pfizer’s COVID-19 vaccine once they’re six months past their last shot.
The U.S. and many other nations already were urging adults to get booster shots to pump up immunity that can wane months after vaccination, calls that intensified with the discovery of the new omicron variant.
On Thursday, the Food and Drug Administration gave emergency authorization for 16- and 17-year-olds to get a third dose of the vaccine made by Pfizer and its partner BioNTech. And hours later, the Centers for Disease Control and Prevention lifted the last barrier — saying those teens should get their booster as soon as it’s time.
CDC Director Rochelle Walensky told The Associated Press the boosters are important considering that protection against infection wanes over time and “we’re facing a variant that has the potential to require more immunity to be protected.”
“Vaccination and getting a booster when eligible, along with other preventive measures like masking and avoiding large crowds and poorly ventilated spaces, remain our most effective methods for fighting COVID-19,” Dr. Janet Woodcock, acting FDA commissioner, said in a statement.
The Pfizer vaccine is the only option in the U.S. for anyone younger than 18, either for initial vaccination or for use as a booster. It’s not yet clear if or when teens younger than 16 might need a third Pfizer dose.
Vaccinations for children as young as 5 began last month, using special low-dose Pfizer shots. By this week, about 5 million 5- to 11-year-olds had gotten a first dose.
The extra-contagious delta variant is causing nearly all COVID-19 infections in the U.S., and in much of the world. It’s not yet clear how vaccines will hold up against the new and markedly different omicron mutant. But there’s strong evidence that boosters offer a jump in protection against delta-caused infections, currently the biggest threat.
