- Only 34.1% of 60-79 year-olds and 26.9% of those aged 80 and over eligible for the second booster shot have actually received it.
- The still active circulation SARS-CoV-2 requires appropriate prevention measures, particularly to protect the most vulnerable, hence the importance of continuing the following:
- self-isolating in the event of symptoms or a positive test for COVID-19;
- taking individual precautions such as mask-wearing (around high-risk people and in crowded indoor places or large gatherings), hand-washing and frequent ventilation of enclosed spaces.
