Several countries including the USA, South Africa and European Union have temporarily stopped administering Johnson & Johnson (J&J) Covid jab, after reports of rare blood clotting.
Six cases were detected in more than 6.8 million doses of the vaccine, the US Food and Drug Administration (FDA) said.
Johnson & Johnson has paused its EU rollout, which started this week.
It follows similar cases after doses of the AstraZeneca vaccine, which prompted curbs to its use.
Countries began halting the use of Johnson & Johnson’s one-shot vaccine Tuesday after federal health officials recommended a pause “out of an abundance of caution” because of rare but dangerous blood clots.
The authorities are reviewing data involving six reported U.S. cases of a rare and severe type of blood clot – cerebral venous sinus thrombosis – in individuals after receiving the J&J vaccine. All six cases were among women 18 to 48, and symptoms occurred six to 13 days after vaccination.
