[The state of measles immunity and the success quota of measles vaccination in Basle nursery and elementary school pupils].

Measles antibody determinations in kindergarten and primary school children in Basle-City showed that today just under 10% of 10-year-olds and roughly 25% of 5-year-olds have no immunity to measles. In the 10-year-old primary school children the effects of measles immunization are not yet markedly apparent, whereas almost half the kindergarten children already owe their measles immunity to immunization. No measles antibodies could be detected in 13,7% of the subjects who, according to their official vaccination certificates, had previously been immunized against measles. Most of these failures are probably due to careless routine immunization techniques.
