The general population can be enlightened and encouraged to get vaccinated by understanding the adverse effects of vaccination. The study aimed at assessing the risk factors and possible systematic side effects of the immunization against coronavirus disease 2019 (COVID-19) by the most used vaccines in Iraq, being the Oxford-AstraZeneca, the Pfizer-BioNTech, and the Sinopharm vaccines. In addition, the study aimed at comparing the side effects between the different vaccine groups. To this end, this cross-sectional retrospective survey-based study was done during August 2022, through a self-administered online-based multiple choice questionnaire that was distributed among the Iraqi population. In total, 215 participants answered the questionnaire from different regions of Iraq, with a response rate of 100%. Of these participants, 13.03% were men and 86.97% were women. A total of 148 (68.8%) of the participants had obvious adverse effects after vaccination, while 67 (31.2%) were asymptomatic. There was a statistically significant correlation (p<0.05) between variables such as sex, age, vaccine dose, history of COVID-19 infection, and comorbidity with the herein recorded side effects. Localized injection pain, fever, fatigue, headache, localized swelling, and myalgia were the top side effects encountered by the present study, with a severity ranging from mild to moderate.
