- Five cases of capillary leak syndrome reported after AZ vaccine on continent
- Condition sees blood leak from tiny vessels into muscles and body cavities
- The issue could mean AstraZeneca jabs being banned for the under-40s
- J&J vaccine was also linked to four cases of brain clots, one of which was fatal
- Use of the jab was stopped in North Carolina following 18 'adverse reactions'Another potentially dangerous blood condition has been spotted in a handful of patients given the AstraZeneca coronavirus vaccine, the EU's drug watchdog has announced.
The European Medicines Authority (EMA) said five cases of capillary leak syndrome had been reported in vaccinated patients on the continent.
The rare condition sees blood leak from tiny vessels into muscles and body cavities, resulting in a sudden drop in blood pressure. If left untreated, it can cause organ failure.
Data suggests the UK's regulator, the MHRA, had spotted three cases of capillary leak syndrome out of 20million people given the AstraZeneca vaccine by late March.
It is another blow for the British-made jab, which has been restricted for certain age groups in various countries around the world, including under-30s in Britain, after reports of rare blood clots in the brain and abdomen.
Officials insisted there is still no evidence the jab causes the blood conditions and stressed the benefits of vaccination far outweighed the risk.
Meanwhile, the EMA revealed it is also reviewing reports of rare clots involving Johnson and Johnson's Covid vaccine, which uses the same technology as AstraZeneca's.
Four serious cases of rare blood clots with low platelets were detected in people vaccinated with the jab, one of which died.
A vaccination site in North Carolina has stopped the use of the jab after 18 people had adverse reactions 'out of an abundance of caution'.
'The reactions people experienced today were consistent with known common side effects from receiving the vaccine,' Wake County officials said in a statement about the adverse reactions at PNC Arena in Raleigh.
Wake County said it will announce 'guidance' about its use in the coming hours after Centers for Disease Control and Prevention experts assess the batches. They have affected less than one per cent of recipients.
Just hours earlier, a similar incident forced a Colorado clinic to shut down. Eleven people suffered adverse reactions 'such as nausea and dizziness' at a pop-up vaccination site at a Dick's Sporting Goods in Commerce City and two had to be hospitalised.
The J&J jab, made by the US-firm's Belgium arm Janssen, had been earmarked by UK officials for young people because it is given as a single dose.
The vaccine has been approved in the EU and was due to be rolled out in the coming months. It is currently under review by the UK's medicines watchdog and the UK Government has ordered 30million doses.
The EMA has said that 'at this stage, it is not yet clear whether there is a causal association' between either vaccines and the reported conditions.
J&J said that it was aware of the reports of blood clots and is working with regulators to assess the data and provide relevant information.
'At present, no clear causal relationship has been established between these rare events and the Janssen Covid vaccine,' the company said in a statement.
