Аннотация

A study was conducted to compare the production of the serum and local IgA-antibodies in persons of different age groups (aged: 3-6, 7-14, 18-30, 65-89) after a single intranasal immunization with trivalent live cold-adapted reassortant of influenza vaccine (LIV). The geometric mean of titers of local IgA-antibodies increased, during post-vaccination period, against influenza viruses A(H1N1), A(H3N2) and B as much as people's age went up. It is noteworthy, that the parameters of the young and elderly did not virtually differ. As for the children, aged 3-6 and especially 7-14, an active local immune response developed in them to the LIV administration. Thus, no pronounced age-related immunologic insufficiency was found in children, aged 3-14, or in the elderly above 65 to the induced local response caused by LIV.
