Soo.... the science has changed direction?
As 98% of Swiss have either been vaccinated or contracted Covid and therefore have natural immunity, and the virus is barely circulating and is mild in its current form anyway, the Swiss reasonably decided there is no need for further vaccinations this spring and summer except in cases where the patient has some other health condition. Sounds like following the science to me. It’s silly to get vaccinated for something you are already immune to and is a mild illness to boot.
