From the BMJ:
'The EMA’s safety committee is reviewing the issue but said that there was currently no indication that vaccination has caused these conditions, which are not listed as side effects. It said that the information available so far showed that the number of thromboembolic events in vaccinated people was no higher than that seen in the general population. It said that, as of 10 March, 30 cases of thromboembolic events had been reported among the five million people given the AstraZeneca vaccine in the European Economic Area.'

Commenting on the decisions, Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, said, “The problem with spontaneous reports of suspected adverse reactions to a vaccine [is] the enormous difficulty of distinguishing a causal effect from a coincidence.” He highlighted that covid-19 disease was very strongly associated with blood clotting and that there had been hundreds, if not many thousands, of deaths caused by blood clotting as a result of covid-19.
Adam Finn, professor of paediatrics at the University of Bristol, said, “The position with the Oxford-AstraZeneca vaccine at the moment is that there is no sign anywhere, including the UK where very large numbers of doses have now been given, that blood clot related illnesses are happening any more frequently than usual.
“That’s reassuring, because it means either that the vaccine doesn’t cause blood clots at all or, at the very worst, that it’s an extremely rare event.”'
Although yes, it's interesting that they all appear to have come from one batch. Which could be indicative of something. Or it could just indicate that that was the batch being used....
Politics and optics vs science and medicine IMHO
