U.S. plans to give extra COVID-19 shots to at-risk Americans, Fauci says

The United States is joining Germany, France and Israel in giving booster shots, ignoring a plea by the World Health Organisation to hold off until more people around the world can get their first shot.

U.S. regulators need to fully authorize the COVID-19 vaccines or amend their emergency use authorizations before officials can recommend additional shots, but the U.S. Centers for Disease Control and Prevention is working to make third doses available sooner under certain circumstances, officials said at a July meeting.

"It is extremely important for us to move to get those individuals their boosters and we are now working on that," Fauci said on a press call, adding that immunocompromised people may not be sufficiently protected by their existing COVID-19 vaccinations.

Fauci said rising cases resulting from the spread of the contagious Delta variant in the United States can be turned around with additional vaccinations.

COVID cases are up about 43% over the previous week and daily deaths are up more than 39%, according to U.S. Centers for Disease Control and Prevention Director Dr. Rochelle Walensky, who also spoke on the call.

The United States hit a six-month high for new COVID cases with over 100,000 infections reported on Wednesday, according to a Reuters tally. read more Some 864,000 vaccinations have been given in the past 24 hours, the highest since early July, the White House said.

Zients said the Biden administration supports U.S. businesses and other institutions requiring that their employees get vaccinated.

He added that the White House is considering requiring foreign visitors to be vaccinated as it plans to eventually reopen international travel but said it had made no final decision.
