[Possibilities of measles vaccination in children with counterindications and duration of preservation of postvaccinal immunity].

A study was made of the clinicoimmunological reactions in 2056 children with different somatic diseases, in children frequently falling ill and in those with tuberculous infection vaccinated against measles. Of these, 912 children were vaccinated after carrying out the treatment and health measures and 1144 children remained without those measures; 192 practically healthy children were vaccinated with the same series of vaccines. The treatment and health measures carried out before vaccination decrease the rate and intensity of the clinical manifestations of the measles vaccinal process and enhance antibody formation.
