[Combined (associated) immunization against typhoid, typhus and plague].

The article substantiates epidemiological expediency of complex (associated) immunization of servicemen and population against typhoid, typhus and plague in polyetiological zones of these infections, and also in cases of simultaneous proliferation of these diseases. For simultaneous preventive vaccination against these infections a complex immunization scheme was experimentally substantiated and clinically approved. It is based on national commercial vaccines and ensures a simultaneous administration of 2-3 vaccine preparations by hypodermic syringe or jet injection. Typhoid and typhus vaccines are injected under one shoulder-blade, and plague vaccine is injected under another shoulder-blade. This complex vaccine is harmless, moderately reactogenic, develops expressing immunity which have the same protective features as monovaccines alone. This scheme is recommended for use in anti-epidemic practice.
