Prevention
- Vaccination on 9 May 2023 (Vaccin Covid data):
- 23.8% of 60-79 year-olds and 26.6% of 80+ year-olds had received a booster dose adapted to the Omicron variant
- 20.0% of 60-79 year-olds had received a dose of vaccine in the past 6 months and 2.0% of 80+ yearolds in the past 3 months
- In the context of the spring vaccination campaign and the active circulation of SARS-CoV-2, continued compliance with preventive measures is recommended:
- up-to-date COVID-19 vaccination, including a booster dose of bivalent vaccine (protecting against the original strain and the Omicron variant) for eligible individuals already vaccinated with a primary series;
- continued application of precautionary measures, particularly in case of a positive test and/or symptoms, to protect vulnerable individuals.
