[Evaluation of vaccinal immunogenesis by the peroxidase method]

Area of Science:

• Immunology
• Vaccinology
• Microbiology

Background:

• Assessing the efficacy of vaccines like those for brucellosis and plague is crucial for public health.
• Understanding the immune system's response (immunomorphogenesis) during vaccination provides insights into vaccine effectiveness.
• Morphological evaluation of immune responses can complement traditional immunological assays.

Purpose of the Study:

• To evaluate functional immunomorphogenesis during the vaccinal process.
• To assess the immune response to conjugated and live brucellosis vaccines, and to a conjugated plague antigen (Yersinia pestis strain EV).
• To establish methods for morphological evaluation of vaccine preparations.

Main Methods:

• Utilized direct and two-layer immunoperoxidase assay techniques.
• Administered conjugated and live brucellosis vaccines, and conjugated plague antigen (Yersinia pestis strain EV) to guinea pigs.
• Monitored the dynamics of globulin-producing cells in immunocompetent organs and immunoglobulin titers in peripheral blood.

Main Results:

• Demonstrated the feasibility of evaluating functional immunomorphogenesis using immunoperoxidase assays.
• Tracked the accumulation of globulin-producing cells and changes in immunoglobulin titers post-vaccination.
• Observed distinct immune responses following the administration of different vaccine types (live vs. conjugated).

Conclusions:

• Immunoperoxidase assays are effective for assessing immune responses to brucellosis and plague vaccines.
• The study provides a morphological basis for evaluating the efficacy of approved vaccine preparations.
• Data on cell accumulation and antibody titers can inform vaccine development and quality control.
