Abstract
Vaccines are not free from adverse outcomes. However, the evidence of adverse outcomes following COVID-19 vaccination among health-care professionals (HCPs) in the study setting was scanty. Aimed to assess outcomes following COVID-19 vaccination and associated factors among health-care professionals in Oromia region, Ethiopia. An online cross-sectional survey was conducted from 1 October to 30 October 2021. Data were collected using questionnaire created on Google forms. A snowball sampling technique through the authors' network on the popular social media was used. Data analysis was performed using SPSS version 25. The Adjusted Odd Ratio (AOR) along with the 95% confidence level and variables with a p value <.05 were considered to declare the statistical significance. About 93.9% of the participants had experienced mild-to-moderate adverse outcomes following COVID-19 vaccination. Being married [AOR = 4.19, 95% CI:2.07,8.45] ,family size >5 [AOR = 5.17, 95% CI: 1.74, 15.34], family not tested for COVID-19 [AOR = 0.39, 95% CI: 0.15,0.97], lack of family support to take the vaccine [AOR = 3.58, 95% CI: 1.75, 7.33], heard anything bad about the vaccine [AOR = 4.17, 95% CI: 1.90,9.13] and very concerned as the vaccine could cause Adverse Events Following Immunization (AEFI) [AOR = 6.24, 95% CI: 1.96,19.86] were statistically associated with the outcome. The study showed that over nine out-of-often participants had experienced mild-to-moderate adverse outcomes following COVID-19 vaccination. However, severe adverse outcome experienced was very low, which could not hinder to take the vaccine due to fear of its side effects. Marital status, family size, family tested for COVID-19, lack of family support to take the vaccine, hearing anything bad about the vaccine, and being concerned about as the vaccine could cause adverse events were factors associated with the outcome.
