The European drugs regulator has found a “possible link” between the Johnson & Johnson vaccine and very rare blood clots detected in some recipients of the jab.
A warning over the clotting, which is combined with low blood platelet counts in the cases of concern, should be listed as a rare side effect for the vaccine, the safety committee for the European Medicines Agency said.
However, it insisted that the overall benefit of the jab in providing protection against Covid-19 outweighs any associated risk.
Based on the currently available evidence, specific factors that might heighten an individual’s chances of developing the blood clots have not been confirmed.
