As of Monday morning, the most recent date for which data was available, more than 120 million people nationwide have gotten at least one dose of the available COVID-19 vaccines, according to the U.S.
J&J said in a statement it was aware of the reports of blood clots, but that no link to its vaccine had been established.
Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said that of the six cases of rare blood clots reported in Americans who received the Johnson & Johnson coronavirus vaccine, one case has so far proved to be fatal.
Health officials are reviewing the available data after six people developed clots similar to cerebral venous sinus thrombosis , a rare, severe blood clot, along with a condition in which people have low blood platelet counts.
Janet Woodcock emphasized that the recommendation to pause administration of the Johnson & Johnson vaccine came out of an “abundance of caution” due to six reports of a “rare and severe type of blood clot” forming in people who have received the single-dose vaccine.
Bruce Vanderhoff released a joint statement Tuesday morning telling vaccine providers to take a “temporary pause” on administering Johnson & Johnson vaccines, according to WHIO-TV.
Original report: Six cases “of a rare and severe type of blood clot” occurred in women who received the single-dose vaccine in the United States, the statement said.
According to The Associated Press, federal distribution channels and mass vaccination sites will pause use of the vaccine.
