[Initial results and evaluation of igg antibody levels for measles, mumps, rubella and chickenpox viruses in young adults born in 1989].

The study presents results of the examination of IgG antibody levels for measles, mumps, rubella and chickenpox viruses in Warsaw high school students born in 1989. Results of the analysis of serum samples were confronted with data from questionnaires filled in by the students, containing information on completed vaccination and cases of the studied infectious diseases. Initial results have been especiallyalarming for the measles virus, as they may testify to a lack of immunity in 22.6% of the studied population, including 22.3% of the respondents declaring completion of vaccination to the measles virus. The results of the study indicate a need to repeat (periodical) serological surveys ofvaccine-preventable diseases, in order to obtain an assessment of immunity levels in different age groups.
