Objectives: The goal was to determine vaccination rates and predictors of vaccination behaviour of pediatricians in Munich, Germany., Methods: Standardised questionnaires were sent to all 133 office-based pediatricians in Munich., Results: 97 questionnaires (73%) were returned completely. Vaccination rates were sufficiently against diphtheria, tetanus, and poliomyelitis only. The other vaccinations recommended by the national immunisation advisory board (STIKO) were carried out to an insufficient extent. Vaccination rates of measles, mumps, and rubella were low. Parents' informed consent to STIKO's recommendations was the main determining factor of vaccination rates. Physicians' uncertainty in assessing contra-indications correctly was another important reason for insufficient vaccination rates., Conclusions: The health target of eliminating measles will not likely be reached. STIKO's recommendations as well as periodically vocational training courses, should be more compulsory to physicians. Self-responsibility of patients and parents should be raised by financial incentives on sick funds premiums.
