Prevention

  • Vaccination as of April 3, 2023 (Covid Vaccine data):

    • 23.4% of those aged 60–79 and 26.2% of those aged 80 and older had received a booster tailored to the Omicron variant;

    • 24.5% of those aged 60–79 and 6.4% of those aged 80 and older had received a dose administered less than 6 and 3 months ago, respectively.

  • Given the ongoing circulation of SARS-CoV-2, it remains recommended to continue adhering to the following combined measures:

    • up-to-date COVID-19 vaccination, including a booster dose with a bivalent vaccine (against the original strain and the Omicron variant) for those eligible who have received their primary series;

    • continued adherence to preventive measures, particularly in the event of a positive test result and/or symptoms, to protect vulnerable individuals.
