[The time course of changes in cell immunological parameters during administration of live dry plague vaccine]

The study of the time course of changes in cell immunological parameters by a magnetic separation technique in human beings during the administration of plague vaccine in relation to the immunological load revealed the higher blood levels of all T lymphocyte subpopulations on day 14 after vaccination. These changes are most typical of a primary vaccinated cohort. The increased frequency of plague vaccine administration and multiple immunizations with live plague, anthrax, and tularemia vaccines produce the time-course of changes in T lymphocyte populations (subpopulations) in response to the regular administration of plague vaccine. A high immunological load in man also promotes a significant reduction in the level of B lymphocytes.
