U.S. drug regulators are set to clear a third dose of Covid vaccines for people with weak immune systems as a new study showed the benefits of an extra shot in transplant patients.
A third dose of Moderna Inc.’s vaccine significantly raised antibody levels against the coronavirus in transplant patients, according a comparison of an extra shot to a placebo in people with weak immune systems. The Food and Drug Administration is set to amend clearances as soon as Thursday for vaccines from both Moderna and Pfizer Inc. to allow extra doses for people with compromised immune systems, according a person familiar with the matter who spoke on condition of anonymity.
