Factbox-Some countries limit AstraZeneca vaccine use, U.S. pauses J&J shot
(Reuters) – Some countries are restricting use of the AstraZeneca COVID-19 vaccine to certain age groups, or suspending use, after European and British regulators confirmed possible links to rare blood clots.
Johnson & Johnson’s single-shot vaccine has also been hit by concerns over blood clots. European regulators are reviewing such cases and are expected to issue findings on April 20. U.S. federal health agencies recommended pausing its use temporarily on April 13 and a U.S. health advisory panel will meet on April 23 to discuss whether the pause should continue.
J&J has stated that no clear causal relationship has been established between the clots and its vaccine.
The developments pose a risk to vaccination plans in Europe, where authorities have so far maintained that the benefits of the AstraZeneca and J&J shots outweigh risks.
As of April 4, the European Medicines Agency had received reports of 169 cases of cerebral venous sinus thrombosis, after 34 million doses of the AstraZeneca vaccine had been given in the European Economic Area. Canada and Australia have also reported some cases.
