US FDA advisers recommend second shot of J&J COVID-19 vaccine

Outside advisers to the U.S. Food and Drug Administration on Friday voted unanimously to recommend regulators authorize a second shot of Johnson & Johnson's COVID-19 vaccine to better protect Americans who received the one-dose vaccine.

The FDA's Vaccines and Related Biological Products Advisory Committee backed the shots for all J&J recipients aged 18 and older at least two months after their first dose.

The FDA is not bound to follow the advisory panel recommendations, but typically does.
