People with COVID-19, both vaccinated and unvaccinated, may be admitted to the hospital. A higher level of vaccination coverage in the community means that a greater proportion of those hospitalized will be vaccinated, but the total number of hospitalized, and of those who will lose their life, is much lower.
This is also the case with seatbelts. Almost everyone wears a seatbelt when driving, so most people who experience a car accident are wearing a seatbelt. Fortunately the seatbelt reduces their risk of serious injury.
COVID-19 vaccines have already saved hundreds of thousands of lives in the WHO European Region.
