Enhancement of long-lasting immunoprotective effect against Androctonus australis hector envenomation using safe antigens: Comparative role of MF59 and Alum adjuvants

One week after challenge, only immunized animals with Alum preparation present an increase in cell infiltration, MPO and EPO activities. These results are correlated with the ability of MF59 adjuvant to induce a potent immunoprotective effect against Aah venom compared to Alum adjuvant.
