SAN FRANCISCO (AP) — University of California, San Francisco officials say a man in his 30s is recuperating after developing a rare blood clot in his leg within two weeks of receiving the Johnson & Johnson vaccine.
As of Friday, the U.S. Centers for Disease Control and Prevention had reported the condition in 15 people, all women, after 8 million doses were administered nationally. Three of the women previously identified died, and seven remain hospitalized.
“To the best of our knowledge, this is the first male patient with VITT syndrome in the U.S. following the U.S. emergency authorization of the Johnson & Johnson vaccine on Feb. 27, 2021,” UCSF said in a statement.
Bloodwork showed he had the same syndrome as the other patients, although initial imaging did not show a blood clot, said UCSF spokeswoman Suzanne Leigh. Physicians later discovered a tiny clot, she said.
Federal officials lifted an 11-day pause on use of the single-shot vaccine Friday, saying the benefits outweighed the risks.
UCSF says the man was admitted 13 days after receiving the vaccination and should be released shortly.
