Abstract
OBJECTIVE: To study whether the rabies vaccine for human use should contain aluminum adjuvant. METHODS: Testing vaccine antibodies and efficacy (ED50), comparing the effect between aluminum adjuvant contained and non-aluminum adjuvant contained vaccines in a new animal model which accords with the rabies field practice. RESULTS: At fourth and seventh day after immunization, the neutralizing antibody titres of the rabies vaccine containing aluminium adjuvant were much lower than that of the vaccine not containing aluminum adjuvant. In the NIH efficacy test the ED50 of the vaccine containing aluminum adjuvant was 93-132 ng while the ED50 of the vaccine not containing aluminum adjuvant was 221 ng, but the NIH test does not accord with the rabies field practice. In that new animal model, aluminum adjuvant to rabies vaccine had not any promoting effect for preventing and treating rabies. CONCLUSION: Aluminum adjuvant to rabies vaccine has no advantages, this paper suggests that the vaccines containing and not-containing aluminium adjuvant had better compare in human bodies. If the results are the same as our experiments, the aluminum adjuvant should be eliminated from rabies vaccine for human use.
