The Biden administration is working to accelerate doses of the Pfizer-BioNTech and Moderna Covid-19 vaccines after U.S. health officials advised states to hold off on using Johnson & Johnson’s shot while regulators investigate a rare blood-clotting issue, a top U.S. official said Wednesday.
Jeff Zients, the White House’s Covid-19 coordinator, said the Food and Drug Administration’s recommended pause on J&J’s vaccine would not have a “significant impact” on the administration’s vaccination program. On Tuesday, the FDA asked states to temporarily halt using J&J’s vaccine “out of an abundance of caution” after six women developed a rare, but serious, blood-clotting disorder that left one dead and another in critical condition.
