The European Medicines Agency’s (EMA) safety committee has added another rare blood condition to the potential side effects of AstraZeneca’s vaccine, as the UK regulator weighs precautionary advice over capillary leak syndrome. 

The EMA’s addition of the very rare syndrome to its list of potential side effects for the AstraZeneca Covid-19 jab comes as the regulator also examines reports of heart inflammation in recipients of the vaccine.

Capillary leak syndrome is a condition that causes fluid to leak out of blood vessels and could cause very low blood pressure, leading to pain, nausea and tiredness or, in the worst case, kidney failure and strokes.

The agency said that the safety committee carried out an in-depth review of six reported cases of the condition among recipients of the AstraZeneca vaccine, over 78 million doses of which have been administered within the EU and UK by the end of May. (RT)
