A decision about whether to resume administering the Johnson & Johnson coronavirus vaccine should come this Friday, when an expert panel that is advising the Centers for Disease Control and Prevention is scheduled to meet, according to Dr. Anthony S. Fauci, the nation’s leading infectious disease expert.
“I think by that time we’re going to have a decision,” Dr. Fauci said on Sunday on the CNN program “State of the Union.”
“I don’t want to get ahead of the C.D.C. and the F.D.A. and the advisory committee,” he added, but said he expected experts to recommend “some sort of either warning or restriction” on the use of the vaccine.
Federal health agencies recommended putting injections of the vaccine on pause on Tuesday while they investigated whether it was linked to a rare blood-clotting disorder. All 50 states, in addition to Washington, D.C., and Puerto Rico, have stopped administering the vaccine.
two more cases of the clotting disorder were identified, including one in a man who had received the vaccine in a clinical trial.
Of the 129.5 million people who have received at least one dose of a Covid-19 vaccine in the United States, more than seven million have received Johnson & Johnson’s. If there is a link between the vaccine and the clotting disorder, the risk remains extremely low, experts say.
“It’s an extraordinarily rare event,” Dr. Fauci said on the ABC program “This Week.” The pause was intended to give experts time to gather more information and to warn physicians about the clotting disorder so that they can make more informed treatment decisions, said Dr. Fauci, who appeared on four TV news programs on Sunday morning.
European regulators have been investigating similar cases of the unusual clotting disorder in people who have received the AstraZeneca vaccine. Some European countries have since stopped administering that vaccine altogether, while others have restricted its use in younger people.
