Side Effects of COVID-19 Vaccination among Indian Population - An Online Survey

Background: India has successfully accomplished the administration of 100 crore doses of Covid-19 vaccination. However, there are not many reports regarding the post-vaccination experience. The aim of this study was to determine the side effects of Covid-19 vaccination in southern part of India.
Methods: An online cross-sectional survey was conducted to collect information related to the post vaccination experience in southern part of India. The prevalence of different side effects along with their 95% confidence intervals were reported. The association of demographic characteristics and co-morbidities with side effects of vaccine were also estimated.
Results: Almost 70% of the survey participants reported at least one side effect. Pain at the site of injection was the most common side effect followed by body pain, fever, fatigue, muscle pain and head ache. The side effects were found significantly higher among the younger adults (ages 18-35 years). Female respondents experienced more side effects than males.
Conclusion: The information regarding the potential side effects identified through this survey study can be useful in educating the community and easing the reluctance towards Covid-19 vaccination.
