COVID-19 vaccine hesitancy in Sri Lanka: A national level survey
Abstract
Objective: It is important to understand the factors associated with vaccination hesitancy for a given population for successful coronavirus disease-2019 (COVID-19) immunization program. This survey aimed to examine the prevalence of vaccine hesitancy and associated sociodemographic factors.
Methods: A cross-sectional online survey was undertaken by circulating through social media platforms. Survey questions included sociodemographics and vaccination acquisition-related questions.
Results: The study comprised a total of 3621 respondents. Over one-fifth of the unvaccinated population were identified as vaccine hesitancy group. Ethnicity and district indicated significant associations with vaccine hesitancy (P < 0.05). Indian Tamils (Odds Radio [OR] 2.222; 95%Confidence interval [CI], 1.150–4.294;
P = 0.018), Sri Lankan Tamils (OR 1.714; 95% CI, 1.181–2.488; P = 0.005), and SriLankan Moors (OR 1.913; 95% CI, 1.316–2.781; P = 0.001) had significantly higher odds of vaccine hesitancy when compared to the Sinhalese. People in rural areas also had greater odds of vaccine hesitancy (OR 1.339; 95% CI, 1.000–1.793; P = 0.05)
compared to municipal council areas.
Conclusion: Vaccine hesitancy was considerably high in this survey population. Our results emphasize the need of the Sri Lankan government taking appropriate efforts to establish a targeted COVID-19 vaccination campaign plan for rural and Colombo district residents. Attention should also be given to ethnic minority groups.
