Sociodemographic and socioeconomic disparities in COVID-19 vaccine uptake in Belgium [Cavillot et al. 2024]

Journal of Epidemiology and Community Health published a study by Cavillot and colleagues with a cross-sectional analysis of the uptake of a first COVID-19 vaccine dose among 5 342 110 adults (≥18 years) in Belgium on 31 August 2021.The aim of our study was to investigate the sociodemographic and socioeconomic characteristics associated with the uptake of COVID-19 vaccine in Belgium.

Four national data sources were used for this purpose: the Belgian vaccine register (vaccination status), COVID-19 Healthdata (laboratory test results), DEMOBEL (sociodemographic/socioeconomic data) and the Common Base Register for HealthCare Actors (individuals licensed to practice a healthcare profession in Belgium). 

The study finds a significant lower COVID-19 vaccination coverage among socioeconomically disadvantaged groups, despite the success of the vaccination campaign in Belgium (89% of adults vaccinated with primary course), free vaccination and the efforts made by the regional health authorities to reach all citizens. More specifically, a lower COVID-19 vaccine uptake was found among young individuals, men, migrants, single parents, one-person households and disadvantaged socioeconomic groups (with lower levels of income and education, unemployed). Overall, the sociodemographic and socioeconomic disparities were comparable for all regions.
