US recommends ‘pause’ for J&J shots in blow to vaccine drive
Associated PressWASHINGTON — The U.S. on Tuesday recommended a “pause” in use of the single-dose Johnson & Johnson COVID-19 vaccine to investigate reports of rare but potentially dangerous blood clots, setting off a chain reaction worldwide and dealing a setback to the global vaccination campaign. Speaking at the White House, Dr. Anthony Fauci, the nation’s top expert on infectious disease, said the pause would allow the FDA and the CDC to investigate the clotting cases and “to make physicians more aware of this.” A CDC committee will meet Wednesday to discuss the cases, and the FDA has launched an investigation into the cause of the clots and low platelet counts. Doctors and patients could still use J&J’s vaccine if they decide its benefits outweigh its risks for individual cases, Marks said. While it’s not clear yet if the reports among J&J recipients are related, doctors would treat these kinds of unusual clots like they treat people who have the heparin reaction — with different kinds of blood thinners and sometimes an antibody infusion, said Dr. Geoffrey Barnes, a clot expert at the University of Michigan. Even without J&J’s vaccine, White House officials said they remain on track to have enough supplies to vaccinate most American adults by the summer.
