So far, nearly 200 million doses of COVID-19 vaccines have been administered in the U.S., including 7.2 million doses of the Johnson & Johnson vaccine. In six cases there have been reports of “a rare and severe type of blood clot” in those who received the J&J vaccine, prompting the Food and Drug Administration and Centers for Disease Control and Prevention to recommend “a pause in the use” of the J&J vaccine “out of an abundance of caution.”
All six cases involved women ages 18 to 48 and their symptoms which included severe headache, abdominal pain, leg pain or shortness of breath occurred six to 13 days after they received the J&J vaccine, the agencies said in a joint statement. One died and one remains in critical condition, Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said in an April 13 press conference.

The European Medicines Agency has concluded there is a link between AstraZeneca’s Covid-19 vaccine and “very rare” but dangerous clotting events reported in a number of countries where the vaccine has been used, events which in some cases have been fatal.
A safety committee, the agency said Wednesday, concluded that “unusual blood clots with low blood platelets should be listed as very rare side effects” of the vaccine.
Regulators stressed that the benefits of the vaccine, which was shown to be 76% effective at preventing Covid infections in a large U.S.-based study, still outweigh its risks. “This vaccine has proven to be highly effective to prevent severe disease and hospitalization,” said Emer Cooke, the EMA’s executive director. “And it is saving lives.”
