Johnson & Johnson to Seek F.D.A. Authorization for Booster Shot

Johnson & Johnson is planning to ask federal regulators early this week to authorize a booster shot of its coronavirus vaccine, according to officials familiar with the company’s plans. The firm is the last of the three federally authorized vaccine providers to call for extra injections, amid mounting evidence that at least the elderly and other high-risk groups need more protection. Federal officials have become increasingly worried that the more than 15 million Americans who received the Johnson & Johnson vaccine face too much risk of severe Covid-19. The Food and Drug Administration on Friday scheduled a meeting on Oct. 15 of its expert advisory committee to discuss whether to grant emergency use authorization of a booster shot of Johnson & Johnson’s vaccine. That is part of a broader effort by the government to shore up the protection provided by all three vaccines. Regulators last month authorized a booster shot for many recipients of Pfizer-BioNTech’s vaccine and are contemplating doing the same this month for recipients of Moderna’s.
