[Investigations on immunity against poliomyelitis (author's transl)].

Six virus laboratories from various parts of the German Federal Republic and West Berlin undertook investigations into polio-myelitis immunity in 1972. A total of 267 persons aged up to 20 years were investigated for neutralizing antibodies against the three types of polio virus. The study showed that from the fourth year of life approximately 70% of the persons investigated had antibodies against all three types of polio virus. In some younger children the equivalent values were considerably lower. After the fourth year of life there were only slight differences in the humoral immunity against the three polio virus types. There was no evidence that the immunity level had deteriorated up to the 20th year of life and thus there is no indication of the necessity for a repeat immunisation at a certain time. The investigation confirmed that three oral administrations of trivalent vaccine, as are now generally recommended as basic immunization in the German Federal Republic, result in a conversion rate of over 90% against each of the three virus types.

[Quantitative and virus specific serum IgM detection in newborns (author's transl)].

Serum IgM concentration was determined in umbilical cord blood samples from 1000 newborns. 34 cases presenting elevated IgM values (greater than or equal to 30 mg%) were tested for virus specific IgM antibodies. We could demonstrate such virus specific IgM antibodies against Cytomegalovirus (4), against Rubella, Influenza A and Influenza B (2 each) and against Coxsackie virus (1). The quantitation of IgM in blood samples of child bearing women showed no elevated values compared to those of non-pregnant women of similar age groups.
