Concerns over AstraZeneca taken 'very seriously', expert says
Concerns over the AstraZeneca jab are being taken "very seriously" and "very thoroughly" investigated, an expert has said, as the UK's drugs regulator investigates reports of blood clots.
Adam Finn, a professor of paediatrics at the University of Bristol and who also sits on the Joint Committee on Vaccination and Immunisation (JCVI) said told BBC Radio 4's Today programme: "What stands out about them is that we see thrombosis, including thrombosis in the cerebral veins, all the time.
"But we don't normally see them in association with a low platelet count - which is a small blood cell which is involved in blood clotting - and so that makes them stand out and makes us think that this is something a little bit different and out of the norm."
Mr Finn said this meant they wanted to understand why this was being caused and whether it is linked to the vaccine.
After being told there had been 30 cases of this kind of blood clot and seven deaths as more than 18 million people received the jab, Mr Finn said it "could potentially" affect the rollout of the vaccine.
He said: "Those figures quoted were up until March 24 and I think we'll hear shortly what's happened subsequent to that in terms of numbers of cases, but we can expect there will have been more in the interim."
Mr Finn highlighted that the risk of COVID-19 is greater for older people and therefore it likely favours them receiving the vaccine, adding: "What we urgently need to understand if this is a causal thing, is whether that risk-benefit ratio stands up when you get down to younger ages."
