WASHINGTON (AP) — U.S. regulators are strictly limiting who can receive Johnson & Johnson’s COVID-19 vaccine due to a rare but serious risk of blood clots. The Food and Drug Administration said Thursday the shot should only be given to adults who cannot receive a different vaccine or specifically request J&J’s vaccine. The decision is the latest restriction to hit the company’s vaccine, which has long been overshadowed in the U.S. by the more effective shots from Pfizer and Moderna. In December, the Centers for Disease Control and Prevention recommended using the Moderna and Pfizer shots over J&J’s because of its safety issues.
