I believe it’s not a lot higher than for the population but it’s a lot higher than the expected risk is for the group that gets the side effects now: young women. That, together with the fact that this group has minimal risk from the disease means it’s concerning. You don’t want to give someone a vaccine with risks of the same order as the disease. Giving AZ to 60+ is still almost no concern even with this rate of adverse effects because they show a lower thrombosis risk and of course a massively higher risk of severe illness or death from the disease. Countries with a mix of AZ and mRNA vaccines like many EU countries can probably use AZ for 60+ and since AZ underdelivers, the rest can take mRNA. Countries that have only or mostly AZ are in a more difficult situation.
