[Immunological effect of vaccination against pneumococcal infection in HIV-infected children].

Aim: To measure level of antibodies to pneumococcal antigens in HIV-infected children vaccinated in the age > 2 y.o. in order to assess clinical effect of vaccination.

[Vaccination of children born from HIV-infected mothers against Haemophilus influenzae type b infection].

Course of postvaccinal period after injection of vaccine against Haemophilus influenzae type b administered simultaneously with vaccines of Russian national immunization schedule was studied in children born from HIV-infected mothers. Good tolerability of the vaccine administered concomitantly with diphtheria-tetanus-whole cell pertussis and inactivated polio vaccines (Imovax Polio), which is comparable with tolerability in healthy children, was demonstrated. Prevaccination titers of antibodies and their dynamics during immunization process were described.
