COVID-19 vaccination

To date, vaccination has been identified as the best means of controlling the COVID-19 pandemic. The monitoring carried out through our studies makes it possible to determine the percentage of people vaccinated and the impact of vaccination campaigns over time. It also enables us to understand the determinants of the choice of vaccination and to study changes in perceptions over time. Taking vaccination status into account also makes it possible to study the risk of reinfection after vaccination or after a first 'natural' infection.
