Predictors and Perceptions of Healthcare Workers Regarding Vaccines Safety in the Initial Phase of COVID-19 Vaccination Drive in Western Part of India: A Regression Analysis.

Background The COVID-19 vaccination was launched in a phased manner by the government of India prioritizing healthcare workers. This study assessed the perception of healthcare workers regarding COVID-19 vaccination. Methods This cross-sectional study was conducted among healthcare workers vaccinated at a tertiary care center of southern Rajasthan. Logistic regression analysis was used to note the association of perception regarding vaccine safety and other variables. Results Out of 3,102, 56.8% were male, and the majority (73.7%) were in the age range of 20-35 years. Out of the total, 80.7% and 73.2% of subjects perceived the vaccine as safe and effective, respectively. The perception regarding the timing of rolling out of vaccine and readiness for COVID-19 appropriate behavior after vaccination was statistically significant (p<0.001). The commonest undesirable effect following vaccination was pain at the injection site. Most of the subjects did not report undesirable effects following vaccination. Logistic regression analysis showed that the involvement in the direct care of COVID-19 patients (OR: 1.58; 95% CI: 1.29, 1.94), the experience of COVID-19 infection in the past (OR: 0.68; 95% CI: 0.50, 0.91), the timing of the rollout of vaccine (OR: 3.60; 95% CI: 3.24, 4.10) showed a significant association with perception of the safety of COVID-19 vaccine. Conclusions The vaccine was perceived safe and effective by healthcare workers and reported minimal undesirable effects. The COVID-19 vaccine safety is also dependent on the past COVID-19 infection, involvement in patient care, and time of rollout of the vaccine.
