Side Effects of COVID-19 Vaccinations

Abstract

In December 2020, the first COVID-19 vaccinations were granted emergency use permission in the US.1.2 billion vaccination doses have been delivered worldwide. However, some individuals are hesitant to get the COVID-19 vaccine due to safety concerns and unwanted effects. In randomized clinical trials of COVID-19 vaccinations, side effects reported included injection site discomfort, redness, swelling, as well as systemic symptoms such as weariness, headache, muscle or joint pain. Serious adverse events were infrequent. Although the majority of side effects were moderate, research found that 50% to 90% of subjects had them. While government-sponsored reporting systems have provided information on side effects, there is a lack of real-world patient-reported data on those who are more likely to have them after getting the COVID-19 vaccine. The study aimed to detect and report adverse effects related with COVID-19 immunization in an online population. Additionally, the study aimed to uncover variables linked to more severe unfavorable effects. These findings may improve public knowledge of harmful effects from COVID-19 vaccinations.
