Vaccinations are among the most important measures to prevent diseases. Thus, some diseases no longer occur or only very rarely, since people have been vaccinated for the most part.
Before vaccines are approved, efficacy and safety must be demonstrated in studies. The independent Standing Vaccination Commission (STIKO) then examines to whom the vaccination is recommended in Germany and when it should be administered most sensibly. The individual consultation by your doctor or the responsible health authority is based on these recommendations.
