Short-term Side Effects of mRNA-based COVID-19 Vaccine Among Jordanian Population; a Cross-sectional Study.

Abstract

One type of the developed COVID-19 vaccines that received emergency permission and was approved by the food and drug administration (FDA) is the mRNA-based vaccine. The aim of this study is to gather information on the Jordanian population's experience with the vaccine's side effects. The study objectives were addressed through a cross-sectional study, which collected information regarding the short-term side effects experienced by the vaccinated individuals within one month following the injection of an mRNA-based COVID-19 vaccine. Data collection was carried out in August 2021. Participants were invited to take part in a self-administered web-based survey created using Google Forms. Among the study's participants (n= 533), about 56% experienced side effects after the first dose of the mRNA-based COVID-19 vaccine. The most commonly reported side effects after the first dose were sore arm at the injection site (91.6%), and fatigue (83.06%). The female gender was significantly associated with experiencing fatigue, discomfort, chills, and hair loss. Being over 30 years old was significantly associated with experiencing cough. Being a smoker was significantly associated with experiencing shortness of breath and gastrointestinal symptoms. The mRNA-based COVID-19 vaccine side effects were common, yet, mild, local, and self-limited. The local pain at the injection site was the most commonly reported side effect. Hopefully, the study's findings will aid in lowering resistance to vaccination.
