The U.S. Food and Drug Administration is planning a new warning for Johnson & Johnson’s Covid-19 vaccine over a rare but serious side effect, Guillain-Barré syndrome (GBS).

The FDA proposed new health warnings for cigarette packages and ads due to small size and lack of an image in current warnings.

The U.S. Supreme Court agreed to hear Merck & Co.’s appeal of a lower court’s ruling that revived hundreds of lawsuits accusing the company of failing to adequately warn patients of the risks of thigh bone fractures associated with its osteoporosis drug Fosamax.
