It's worth pointing out that if the population vaccinated with AZ had been unvaccinated instead, then given the base frequency of Covid cases and how often severe clotting shows up in Covid cases we should have expected several hundred cases of severe clotting in the same population. Which isn't to say this isn't a potential problem. The very fact that Covid causes clotting problems lends credence to the idea that the vaccine against it could do the same thing through an auto-immune pathway. But we're in the middle of a pandemic, this problem happens in at most a tiny number of people, and I'd take this vaccine in a heartbeat.
