[Content of A-, G- and M-class immunoglobulins in adults perorally immunized with a liver Sonne dysentery vaccine].

The authors studied the immunological shifts in the blood and saliva of 357 adults immunized with live enteral dysentery Sonne vaccine from a spontaneous mutant according to different schemes (1, 2, 3, 4 injections at 2--3-day intervals. The general level of IgA, IgG, and IgM increased during the immunization; there was also an elevation of the specific antibodies level of these classes in the blood of the persons vaccinated. Accretion was the greatest of IgA both in the blood and in saliva of the immunized persons; this pointed to a marked, chiefly local, immunological activity of the vaccine.

[Test of the safety, reactogeneity and immunogeneity of live Flexner 2a and Sonne dysentery vaccine from spontaneous mutants, prepared in dragee form, in a controlled experiment on adults].

Controlled experiment was conducted on 428 adult persons. A study was made of the reaktogenic properties and the immunological activity of live enteral dysentery vaccine Flexner 2a and Sonne from the spontaneous mutants developed at the N.F.
