Various types of adverse events following immunisation (AEFI) after first and second doses of COVISHIELD vaccination. Study participants presented with various types of adverse events after vaccination. The adverse events observed after first-dose vaccination were similar to those observed after second-dose vaccination. The only local adverse event reported by half (52%, 51%) of the participants was pain at the injection site. The six most commonly reported systematic adverse events in descending order of percentage were headache, fever, weakness, body pains, feeling feverish and generalised malaise.
