Abstract

One antibody for all and all antibodies for one Antibodies against related flavi-viruses such as dengue (DENV) and West Nile (WNV) can cross-react with Zika virus (ZIKV) and could thereby increase disease severity. Bardina et al. tested whether DENV and WNV antibodies from humans, or even yellow fever vaccination, could enhance ZIKV infection. In a mouse model, low titers of DENV and WNV antibodies enhanced ZIKV viremia, especially in the spinal cord and testes, whereas high titers remained protective. Generally, WNV antibodies were less disease-enhancing than DENV antibodies, and, in macaques, yellow fever vaccination had very little effect. Science , this issue p. 175
