For millions of adults who have gotten the Johnson & Johnson Covid-19 vaccine, and millions more waiting for the single-dose vaccine, news that the US Food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention (CDC) are recommending a pause on distribution wasn’t the best way to start the day. The agencies’ concerns come after six instances of women, all between the ages of 18 and 60, who had developed rare blood clots near their brains and low platelet counts shortly after getting the shot. The clinical trial data Johnson & Johnson has provided authorities don’t suggest the vaccines could be linked to these blood clots in any way.
