Sao is a surface area protein recently identified as a potential vaccine candidate. less recovery from postmortem tissue samples than did the control group. Furthermore, this study also revealed that although challenge strains express Sao size variants, recombinant Sao conferred cross-protection. These data demonstrate that recombinant Sao formulated with Quil A triggers strong opsonizing antibody… Continue reading Sao is a surface area protein recently identified as a potential
