Grand Hôpital de Charleroi (GHdC) staff were exposed to the risk of SARS-CoV-2 infection during the first half of 2020: a seroprevalence survey, conducted in the summer of 2020, after the first wave of the epidemic, and before the second wave, thus revealed a significant seroprevalence because of its exposure. This study, because of its high participation rate, also showed the sustained interest of the agents in knowing their serology, either for personal reasons, or for the purposes of recognition as an occupational disease.~The GHdC decided in December 2020 to organize as soon as possible the vaccination of its salaried and self-employed employees who wish to take advantage of this opportunity. On the sidelines of this vaccination campaign, the management committee agreed to document the knowledge of the SARS-Cov-2 serology of all the staff of the establishment before this vaccination campaign, as well as a few weeks after vaccination. This knowledge must better organize the disease prevention strategy, both with regard to the staff themselves and the patients for whom they are called upon to treat.~When the Belgian government decided in November 2021 to offer a third dose of vaccine and start it up in hospitals, the GHdC managment committee has agreed to continue monitoring SARS-CoV-2 serology for members who agree to receive their third dose of vaccine.
