[Regional survey of the vaccination rate of 5th grade students exemplified by a rural district in Bavaria].

It was the purpose of this investigation to get a survey of the vaccination rate of eleven-to-twelve-year old pupils in a rural district of Bavaria. We could get the facts by checking the international certificates of vaccination during the medical examination of children in the fifth class of primary schools. The results show that the vaccination rate against polio and tetanus was sufficient, incomplete against diphtheria and insufficient against German measles, mumps and measles. Due to the good cooperation with the primary schools we could get the facts by studying thoroughly 75% of the pupil's certificates of vaccination. A regional survey is a good and inexpensive way of obtaining information on the vaccination rate and it is the last opportunity to achieve a systematic survey of the vaccination rate of children of a certain age. The sero-conversion rate cannot be judged by such a regional survey of the vaccination rate.
