Study Details

Study Description

Brief Summary

A study based on electronic heath records will evaluate the incidence and relative risk of safety concerns and adverse events of special interest (AESIs) following immunisation by AZD1222 in the real-world setting.

A cohort and a self-controlled case series desings will be used.

Condition or Disease Intervention/Treatment Phase
  • Biological: AZD1222

Detailed Description

This retrospective study based on electronic heath records will evaluate the incidence and relative risk of safety concerns and adverse events of special interest (AESIs) following immunisation by AZD1222 in the real-world setting. The primary study objectives are to (1) describe baseline characteristics of all individuals who receive at least one dose of AZD1222 over the study period; (2) describe, among subjects who receive a first dose of AZD1222, the timing and type of second dose of any COVID-19 vaccine over the study period; (3) describe the incidence of prespecified AESIs in subjects who have received at least one dose of AZD1222 and in matched unvaccinated subjects; and (4) estimate any increased risk of prespecified AESIs following vaccination with AZD1222 using study retrospective cohort and self-controlled risk interval designs. Secondary objectives are identical to the primary, although focused on specific populations considered to have missing information, specifically (a) women who are pregnant or breastfeeding, (b) immunocompromised patients, (b) frail patients with certain comorbidities, (c) patients with autoimmune or inflammatory disorders, and (d) patients who, at cohort entry, had recently received a number of selected vaccines to prevent diseases other than COVID-19. A cohort and a self-controlled case series desings will be used.
