U.S. regulators are calling for Johnson & Johnson vaccinations to pause after reports and severe blood clots in six individuals.
The Food and Drug Administration [FDA] and the Centers for Disease Control and Prevention [CDC] confirmed that the agencies are reviewing data involving six reported US cases of women suffering from blood clots called cerebral venous sinus thrombosis [CVST].
The CDC will convene a meeting of the Advisory Committee on Immunization Practices [ACIP] on Wednesday to further review these cases and assess their potential significance. FDA will review that analysis as it also investigates these cases. Until that process is complete, the agencies are recommending a pause in the use of this vaccine out of an abundance of caution, the agencies said in a statement on Tuesday.
