I have linked to this before but I like it so much I will link to it again: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/976877/CovidStats_07-04-21-final.pdf https://assets.publishing.service.gov.uk/government/uploads/... The TL;DR is that for people 20-29, in the case where there is a low level of Covid-19 expected to be circulating in the community ("low" meaning incidence of around 2 in 10,000), the balance of risk vs harm is against taking the AZ vaccine if offered. In every other case (older age group or higher incidence of covid), the balance is in favour of AZ. Of course, this doesn't account for the possibility that the patient has a choice of vaccines.
