Evaluation of water-in-oil-in-water multiple emulsion and microemulsion as potential adjuvants for immunization with rabies antigen.

Water-in-oil-in-water (W/O/W) multiple emulsions and microemulsions have been studied as potential candidates to be formulated as adjuvants. In this work their application as adjuvants for rabies virus immunization was studied. The humoral response, the effective dose 50 and histology for the developed formulations were evaluated in mice and compared with those from traditional adjuvants.
