Assessment of results of immunization against measles and mumps in children with recurrent respiratory infections.
Levels of IgG against measles and mumps viruses were measured using enzyme immunoassay. Two hundred and twelve serum samples obtained from 6 groups of children with 20 - 45 persons (boys and girls) in each were tested. Children of various ages were presented in each group. Also, immunologic parameters were measured in all children.
It was established that mean antibody titers to measles and mumps viruses did not change during 10 years. In more than 50% of children correlation between high and low titers of antibodies of different specificity was found.
Recurrent respiratory illnesses determine complex regulation of transition of memory cells into cells secreting antibodies to measles and mumps viruses.
