The Food and Drug Administration and the Centers for Disease Control will stop using the vaccine at federal sites and urge states to do so as well while they examine the safety issues.

WASHINGTON — Federal health agencies on Tuesday called for an immediate pause in use of Johnson & Johnson’s single-dose coronavirus vaccine after six recipients in the United States developed a rare disorder involving blood clots within about two weeks of vaccination.

All six recipients were women between the ages of 18 and 48. One woman died and a second woman in Nebraska has been hospitalized in critical condition.

Nearly seven million people in the United States have received Johnson & Johnson shots so far, and roughly nine million more doses have been shipped out to the states, according to data from the Centers for Disease Control and Prevention.
