Immune tolerance to self-glycans is a host mechanism to avoid autoimmunity, which is exploited by HIV-1 coating its envelope glycoproteins with glycans to evade neutralising antibodies (nAbs). Huettner et al. describe cross-reactivity between Schistosoma mansoni glycans and HIV-1 envelope glycoprotein glycans, suggesting a strategy for induction of HIV-1 nAbs by vaccination.
