Objective To test the immune therapeutic effects of PICKCa adjuvant rabies vaccine for the post-exposure mice and beagle dogs and immune memory effect for human.Methods For the mice and beagle dogs first to infect with rabies wild virus and then immunize with PICKCa rabies vaccine.For volunteers, first to immunize with PICKCa rabies vaccine after 2.5 years to take peripheral blood mononuclear cell and then to check cells secreted interferon-gwith flow cytometry. Results In 3 independent assays of post-explosure immunization of mice and beagle dogs PICKCa rabies vaccine were much better then commercial adjuvant-free rabies vaccines, the protective rate from 20%-30%to 70%-100%Also, in the assay of cells secreted IFN-γby peripheral blood mononuclear cells from volunteers immunized by PICKCa rabies vaccine the IFN-γcell levels were much higher than control.Conclusions Compared with commercial adjuvant-free rabies vaccines the PICKCa rabies vaccine had significant immune therapeutic effects in the mice and dogs.Also PICKCa rabies vaccine had good immune memory effect in human.
