U.S. regulators on Monday added a new warning to Johnson & Johnson’s COVID-19 vaccine about links to a rare and potentially dangerous neurological reaction, but said it’s not entirely clear the shot caused the problem.

AdvertisementThe CDC and the Food and Drug Administration have been monitoring side effect reports submitted by physicians, drugmakers and patients to a federal vaccine safety database. But there have been rare cases in which people develop the disorder days or weeks after receiving certain vaccines.
