Resumo

The immune response to standard scheme of seasonal vaccination against influenza was evaluated in HIV-infected patients without specific antibodies to influenza virus before vaccination. Titers of hemagglutinating antibodies to antigens of influenza virus A (H1N1), A (H3N2) and B were detected in standard agglutination inhibition test: before vaccination (day 0) and after it (on 21th and 150th days). Coefficient of seroconversion varied from 1.6to 2.3, seroconversion rate varied from 0to 25%); seroprotection rate - from 67% to A (H1N1) to 100% to A (H3N2) and B. Titer of antibodies detected on day 21 retained in all cases up to day 150 after vaccination. The minimal protective level of antibodies (1/40) was detected in the majority of vaccinated persons, including the at least fourfold increase of it in patients with CD4-cells level more than 350/pl.
