Иркутска. Концентрацию антител в сыворотке крови определяли методом иммуноферментного анализа с применением набора реагентов иммуноглобулинов G (IgG) к вирусу кори. Содержание IgG к вирусу кори у детей в возрасте 3‒5 лет 0,67 ± 0,06 МЕ/мл; в группе детей, не прошедших плановую ревакцинацию – 0,46 ± 0,03 МЕ/мл; у ревакцинированных детей в возрасте 6‒7 лет – 0,68± 0,06 МЕ/мл; в возрасте 12‒13 лет – 0,47 ± 0,04 МЕ/мл и у подростков в возрасте 15‒17 лет – 0,42 ± 0,05 МЕ/мл. Доля серонегативных результатов во всех возрастных группах превысила 7%, исходя из этого, уровень напряженности коллективного иммунитета к вирусу кори недостаточен. Необходимо продолжать изучение специфического иммунитета к вакциноуправляемым инфекциям у детей разных возрастных групп и индивидуальных особенностей формирования противоинфекционного иммунитета.</p></abstract><trans-abstract xml:lang="en"><p>Evaluate the efficacy of measles immunization in Irkutsk’s child population by measuring serological anti-measles antibody levels.</p><sec><title>Materials and methods</title><p>Materials and methods.

Measles virus immunoglobulin G concentrations varied among children of different age groups. Children aged 3-5 years had a concentration of 0.67 ± 0.06 IU/ml.

For those aged 12-13 years, the concentration was 0.47 ± 0.04 IU/ml, and adolescents aged 15-17 years had a concentration of 0.42 ± 0.05 IU/ml. The concentration in children aged 3-5 years who did not undergo routine revaccination (Group 2) was 0.46 ± 0.03 IU/ ml.</p></sec><sec><title>Discussion</title><p>Discussion.
