I wish this article reported the denominator. 25 out of how many doses administered? What is the baseline % of people who should have gotten thrombosis naturally in the last 3 months (since doses started being administered). Perhaps the answer is that this is a real risk. But the public should be taught to think in relativistic ways. It's not that hard if every newspaper always did it as reinforcement.
It’s 8 incidents out of 18.1 million vaccinations according to the UK government’s own report. The prevalence generally is estimated to be between 2 and 5 per million per year [1] in a 2016 paper. Given the population prevalence, you’d expect 36 to 100 incidents in the vaccinated population. Yet they found only 8. I’m not qualified to say whether that means anything.

It's also worth looking at the age distribution. The cases that are thought to be linked with AstraZeneca are with younger people. I wonder how that compares to the baseline thrombosis age distribution.
