J&J pause shouldn't prompt vaccine hesitancy: Fauci

U.S. federal health agencies on Tuesday recommended pausing use of J&J's COVID-19 vaccine for at least a few days after six women under 50 developed rare blood clots after getting the shot.

Dr. Anthony Fauci, Biden's chief medical adviser, said on Wednesday that the pause should not prompt vaccine hesitancy.

"It should reinforce in those individuals how we take safety so seriously," Fauci said.

White House COVID-19 response coordinator Jeff Zients said the White House had taken action to speed up production and delivery schedules for Moderna Inc and Pfizer Inc vaccines in a bid to offset the pause in J&J dose shipments and maintain the pace of the United States' inoculation program.

He said J&J shots have so far made up less than 5% of the more than 190 million COVID-19 vaccine doses that have been administered in the United States.
