Non-Interventional Enhanced Active Surveillance Study of Adults Vaccinated With AZD1222

The main data sources for the study will be participants and their medical records. Vaccination details will be verified by a vaccination card, batch/lot number, and/or using a regional vaccination register. Participants will report all study outcomes using the study app, web portal, or call centre. Participants can also select a proxy to communicate on their behalf: a caregiver, family member, or other trusted individual. Participants will be asked for an emergency contact in case of death or incapacity.
