J&J Vaccine and Blood Clots: A Risk, if It Exists, Is Tiny
The New York Times
Out of an “abundance of caution,” the F.D.A. is advising doctors to pause the Johnson & Johnson vaccine while it investigates extremely rare blood clots.
On Tuesday morning, U.S. federal health regulators recommended a pause in the use of Johnson & Johnson’s Covid-19 vaccine while they investigated six reports of blood clots in women ages 18 to 48. One has died, and a second is hospitalized in critical condition. As of Monday, 6.8 million people in the United States had received the vaccine without any other serious adverse reactions reported. Experts have yet to determine to what extent, if any, the vaccine is responsible for the clots. But the investigation follows actions by European regulators who concluded that a vaccine made by AstraZeneca may also be the cause of a similar, extremely rare clotting disorder.More Related News
