[Indices of humoral antimeasles postvaccinal immunity].

Inoculation to children of live measles L-16 vaccine was found to cause changes in the content of the main serum classes of immunoglobulins, A, M and G, and synthesis of specific antibody of various physico-chemical nature. Between these two values only a relative correlation was observed at 10--14 and 28--32 days after vaccination. Changes in the synthesis of serum immunoglobulins in the majority of the children were not great and statistically insignificant. Only in 2 children with hypergammaglobulinemia inoculation of measles L-16 vaccine induced intensive (statistically significant) increase in serum M and G globulins. The results indicate the necessity of further study of the effects of live measles vaccine on the immunological status of children which could probably reveal the causes of occurrence of unusual postvaccination reactions and complications.
