Responses toward most antigens showed highly significant differences in sample means (p-values < 0.0001) between vaccinated and unvaccinated macaques using anti-rhesus IgG-PE ( Fig. 5 A), with the exception of an envelope from a chimpanzee-derived strain (cpzEK505 gp120) and the two PR55 variants tested.
