| Abstract | ||
| Introduction: Rabies cell culture vaccine (Vero-Rab) showed to be more immunogenic and a higher and faster release of antibody titer could be detected than in case of using Fermi type vaccine, DEV and CECV. Result: The immune response of NIH mice immunized intramuscularly using both vE - Se adjuvated and non adjuvated Vero cell rabies virus vaccine (Vero-Rab) showed an elevation of antibody level of vaccinated mice groups more than the limits decided by WHO for a potent rabies virus vaccine. Also, two different immunization regimens were achieved, 5 single doses and 3 double doses of vE-selenium adjuvated and non adjuvated Vero cell rabies virus vaccine. The antibodies developed against rabies virus vaccine could be detected 14 days post immunization using ELISA and IFA. The antibody level developed in sera of mice immunized, with either adjuvated and non adjuvanted Vero-Rab., using different immunization regimens, could protect mice against the challenge with 100 MICLD50 of the challenge virus standard (CVS) after the end of the experiment, (6 months of the prim-vaccination).Conclusion: vE-Se as immune potentiator can enhance the immune response and single dose immunization regimen without vE-Se as immune stimulant was preferred than double dose regimen. | ||
