[Current problems of vaccination, especially in France (author's transl)].

Although being a routine procedure, the vaccination almost daily confronts the physician with problems. The contraindications for vaccinations are either misjudged or overestimated. The approach to be assumed in case of a pregnant woman or a patient of old age is often poorly defined. The order of vaccinations to be observed prior to intercontinental travels is generally ignored. However, in view of the regression of most of the infectious diseases, prophylaxis by vaccination must not slacken. For the rest, intensive research is carried on at present to further improve the existing vaccines and to produce vaccines against new diseases.
