[Protective effect of the aerosol immunization of mice with the polycomponent vaccine Immunovac VP-4 after the challenge of the animals with Klebsiella pneumoniae virulent strain].

Used four schemes of the administration of the preparation with different time of the exposition of the animals in an aerosol chamber were tested with their subsequent intraperitoneal challenge with K. pneumoniae virulent strain K16. Irrespective of the number of immunization courses, the administration of the preparation made at intervals of 1 day, or daily, did not ensure any protective effect, but only led to an insignificant increase in their survival time in comparison with nonimmunized animals.
