The CDC and FDA called for a temporary but immediate halt to the use of J&J’s COVID vaccine while they investigate at least six cases of potentially dangerous blood clots in people who received the vaccine.
Federal agencies today said they will stop using the single-shot Johnson & Johnson (J&J) COVID vaccine at mass vaccination sites while they investigate the vaccine’s possible link to potentially dangerous blood clots. States and other providers also are expected to pause vaccinations.
In a joint statement from the Centers for Disease Control and Prevention (CDC) and U.S. Food and Drug Administration (FDA), the agencies said they are investigating six cases of blood clots in the U.S. All six occurred in women between the ages of 18 and 48, and symptoms occurred six to 13 days after vaccination.
One woman died and a second woman in Nebraska was hospitalized and is in critical condition, The New York Times reported. The CDC will convene a meeting of the Advisory Committee on Immunization Practices Wednesday to further review the cases and assess their potential significance. The FDA will review that analysis, according to the joint statement.
