US federal health agencies have recommended pausing the use of Johnson & Johnson's single-dose Covid-19 vaccine after six recipients developed a rare disorder involving blood clots.
The US Centers for Disease Control and Prevention will hold an advisory meeting tomorrow to review the cases. All the six recipients were women between the ages of 18 and 48.
One woman died and a second in Nebraska has been hospitalised in critical condition, the New York Times reported, citing officials.
The CDC and the US Food and Drug Administration said in a joint statement that the adverse events appear to be extremely rare right now.
