[Interrelationships between serum and secretory antibodies in immunization with live influenza vaccine].
A study was made of the accumulation of antibodies in the blood serum and the secretions of the respiratory tracts of persons immunized with the living influenza vaccine. The duration of inductive phase and the dynamics of the antibody accumulation in the secretions occurred irrespective of their initial level in the blood sera, this pointing to the autonomic character of the local immunity system. On the other hand the functional condition of the system of local immunity influenced the intensity of the antibody formation in the system of the general immunity. If before the immunization the antibody titre in the secretions were 1:4 and greater, the antibody accumulation in the blood sera took place less intensively. An analogous phenomenon was also observed when the antibodies were absent in the secretions before the immunization, but their formation took place as soon as the first week after it. The mechanism of this peculiar "competition for the antigen" of the systems of local and general immunity consisted in the neutralization of the influenza virus in the area of the porta of infection.
