title: [Immunoenzyme analysis of post-vaccination secretory immunity to influenza A and B viruses using a manufactured monoclonal immunoenzyme test system].
abstract: The formation of postvaccinal secretory immunity to influenza A and B viruses was studied by a new monoclonal enzyme immunoassay test system for measuring specific secretory IgA in young people vaccinated with live cold-adapted vaccines (LCAV) intranasally and with inactivated commercial centrifuged influenza vaccine (IIV) parenterally, intranasally, and orally. Secretory IgA most intensively accumulated in subjects intranasally vaccinated with LCAV, less so in subjects vaccinated with IIV intranasally and orally, and just negligibly in those vaccinated with IIV parenterally. In vaccinees immunized with LCAV intranasally the intensity of immune secretory response depended on the initial concentrations of specific IgA before vaccination. Intranasal administration of LCAV in the presence of high concentrations of secretory IgA led in some subjects either to a decrease in the incidence of conversions or to a 2-8-fold drop of their initial titers. Parenteral injection of IIV caused the most expressed suppression of the immune response in the secretory immunity system. Use of biological stimulant adaptogen increased 2.2 times the incidence of conversions of secretory IgA in subjects intranasally vaccinated with LCAV.
