The Food and Drug Administration and the Centers for Disease Prevention and Control said Tuesday morning that they are stopping the rollout of the single-shot Johnson and Johnson vaccine over concerns about blood clots.
The pause in the rollout came after six recipients in the United States developed “a rare and severe type of blood clot” within about two weeks of vaccination.
All six recipients were female and aged between 18 and 48. One woman has died and a second woman in Nebraska has been hospitalized in critical condition, the New York Times reported.
To date, over 6.8 million people have been given the Johnson and Johnson vaccine with nine million more doses already shipped to states.
In a statement, the Food and Drug administration said: “We are recommending a pause in the use of this vaccine out of an abundance of caution. Right now, these adverse events appear to be extremely rare.”
