Objective and Methods: A complete vaccination status against infectious diseases is important for protecting health care professionals as well as patients. A survey based on a written questionnaire was conducted to record the actual vaccination status against diphtheria, hepatitis A und B, mumps, measles, poliomyelitis, rubella and tetanus. 642 general practitioners (family physicians and surgeons), 298 medical students and 962 nursing students from areas of eastern Germany completed the questionnaire. Results and Conclusions: There was no complete vaccination status against those diseases covered by the survey. Physicians had a good immunisation rate against tetanus (96.2%) and diphtheria (91.8%). The number of physicians without immunisation against measles (42.9%), HA (29.3%) and HB (12.7%) was unsatisfactory. Less than 50% of nursing students and medical students could show a complete vaccination status against MMR. In both student groups there were also gaps for vaccines against tetanus, diphtheria, HA and HB. Complete vaccination status was found to be in the range of 74-81% for tetanus, 51-66% for diphtheria, 47-63% for HA and 62-73% for HB. Furthermore, there is a need for actions to raise the immunisation rates and for improving the health protection for all persons involved (professionals and patients) in the health care system.
