Variants
- The recombinant XBB.1.5 remained in majority with 52% of sequences in the week 15 Flash Survey (vs 57% in week 14)

Prevention
- Vaccination on 2 May 2023 (Vaccin Covid data):
- 23.7% of 60-79 year-olds and 26.5% of 80+ year-olds had received a booster dose adapted to the Omicron variant
- 20.8% of 60-79 year-olds had received a dose of vaccine in the last 6 months and 2.4% of 80+ yearolds in the last 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.
