It appears cellulitis not an entirely uncommon reaction to AZ. 104 cases between 4 Jan and 25 February in the UK. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/966183/COVID-19_AstraZeneca_Vaccine_Analysis_Print.pdf …. Very open to commentary from health practitioners.

According to a quick review I did, the yearly incidence of cellulitis appears to be about 2-3% per year in the UK, which is about 0.15-0.3% per month. Now, those two aren't perfectly comparable, but it gives you an idea of what you'd expect to see regardless of vaccinationpic.twitter.com/FUcSxgyJAn

But it's even more complex than that. They UK "Yellow Card" system is a voluntary reporting mechanism that definitely won't capture every case of cellulitis following vaccination. So the 104 is almost certainly an underestimate

Thanks. Obviously extremely low. What about relative risk as compared to other reactions? And is there a particular risk/incidence rating/threshold that would warrant attention?
-
The Yellow Card system (and similar monitoring systems) aren't really set up to describe the frequency of reactions, they are there to identify potential signals so that they can be properly investigated. I don't think you can say much about the relative reporting frequency tbh

Worth noting that the aggregation of yellow card reports for suspected vaccine reactions so far includes... clavicle fracture. Post hoc ergo proctor hoc doing some heavy lifting there.

Yes, exactly. It also includes "Poor diet" and "Tobacco use" which I reckon are pretty hard to blame on the vaccine. Reporting systems are great for some things, not so great for others!
