The federal government called for a “pause” on injections of the single-dose Johnson & Johnson coronavirus vaccine this week after six U.S. women between the ages of 18 and 48 experienced a rare, severe form of blood clotting six to 13 days after receiving their inoculations.
One woman, a 45-year-old from Virginia, has died. Another is in critical condition. And there may be more cases out there we haven’t even heard of.
