We have designed this study to evaluate COVID-19 vaccine effectiveness by antibody testing and evaluate vaccine hesitancy rate, among the healthcare workers of Max Group of Hospitals. We would do antibody testing at day 0 (vaccination day or pre-vaccination) followed by 7, 14, 28, 45, 90th day of vaccination. This study would involve a brief questionnaire asking about the health status of the participants related to COVID-19 and side-effects post-vaccination.
