[Evaluation of a pilot study on measles vaccination in Bavarian preschool children].

Several areas of Bavaria show measles vaccination coverage in preschool children below 95%. Repeated outbreaks could be attributed to this situation. A recollection model in nurseries was tested in order to document the vaccination rate in this age group and to measure the percentage of vaccinations due to intervention. Parents of new entrants to nurseries in a randomly selected rural district were asked to provide measles vaccination records of their kids and to fill in a questionnaire. 121 out of 144 vaccination records (85%) documented a complete immunisation status for measles. 12 children had not been vaccinated against measles, 10 children had received one vaccination. Eight out of these 22 children obtained supplementary measles immunisation at the time of ascertainment. The results provided are of limited statistical significance due to the small sample size. Further intervention studies have to be conducted and should even include measures supported by legal regulations.
