Use of the Johnson & Johnson Covid-19 vaccine stopped last week after federal health agencies recommended a “pause” in the vaccine’s distribution while they investigate a rare blood-clotting disorder that occurred in six recipients in the United States.
All six of the recipients who experienced this disorder, known as cerebral venous sinus thrombosis (CVST), developed the illness within three weeks of vaccination and were women between the ages of 18 and 48; one has died. So far, over seven million people in the US have received the Johnson & Johnson vaccine, with one million of them being women within that age group.
