Social differences in COVID-19 vaccination

Wednesday 1 February, 2023, 12h-13h CET

About the webinar

COVID-19 vaccination has been demonstrated to be an effective public health prevention tool during the crisis. COVID-19 vaccines have been shown to lower the risk of developing severe COVID-19 infections and of dying due to COVID-19. Although Belgium has a high overall COVID-19 vaccination coverage, there are still differences between population groups with regard to vaccination willingness and uptake.

In this webinar, leading experts provided more information on social differences in COVID-19 vaccination in Belgium, potential explanations for these differences and strategies to prevent them.
