Adverse events following immunisation (AEFI) of COVISHIELD vaccination among healthcare workers in Ghana.

ABSTRACT:

Objective

To describe the incidence of adverse events following immunisation (AEFI) and determine the factors that affect the onset and duration of AEFI after COVISHIELD vaccination among healthcare workers.

Design

Prospective cohort study.

Setting

Tertiary healthcare, Korle-Bu, Ghana.

Participant

Three thousand and twenty-two healthcare workers at least 18 years of age were followed up for 2 months after receiving two doses of the COVISHIELD vaccine.

Primary outcome

The occurrence of the AEFI was identified by self-reporting to the AEFI team members.

Results

A total of 3022 healthcare workers had at least one AEFI (incidence rate of 706.0 (95% CI 676.8 to 736.1) per 1000 doses) with an incidence rate of 703.0 (95% CI 673.0 to 732.0) per 1000 dose
