Guidance on COVID-19 Vaccination

The Add-Aspirin Trial Management Group encourages everyone on the Add-Aspirin trial to have a Covid vaccine if they are advised to do so by their hospital doctor or GP. Add-Aspirin trial participants should tell the nurse or doctor that administers the vaccine that they may be receiving aspirin. There can be some bruising associated with an intramuscular injection. Add-Aspirin trial participants who are already experiencing any bruising or minor bleeding should inform the vaccination team before the vaccination is administered. Add-Aspirin trial medication can be withheld (for example 5 days either side of the vaccination) if there are any specific concerns.
