What the vaccinations seem to be really really good at is preventing severe cases, and that's what i hope my shot will give once i get it, but I think there might be no such thing as herd immunity for corona. Or as Christian Drosten, ine of germanys leading viroliogists said recently: this will go from pandemic to endemic, in the next 1,5 years (for germany) everyone wil get some immunity, either from vaccinations or from infections. So he suggests that basically everybody whl does not get vaccinated will get the virus and everybody should make their own risk assessment based on this.
