[email protected] In Brief Alter et al. demonstrate that vaccine- elicited antiviral antibodies can partially protect subjects from viral challenge in a non-human primate model of HIV infection. To demonstrate this proof of concept, the authors purify and transfer polyclonal IgG from vaccinated macaques showing a putative protective antibody signature to naive individuals. The signature, defined by systems serology, includes multiple antibody functions in the absence of broadly neutralizing antibodies. Highlights d We defined a putative protective SIV signature based on multiple antibody functions d Passive transfer of IgG from vaccinated macaques partially protected against SIV d These data demonstrate protective efficacy of vaccine- elicited antibodies in macaques Alter et al., 2020, Cell 183, 185–196 October 1, 2020 ª 2020 Elsevier Inc. https://doi.org/10.1016/j.cell.2020.08.033 ll ll Article Passive Transfer of Vaccine-Elicited Antibodies Protects against SIV in Rhesus Macaques Galit Alter,1 Wen-Han Yu,1 Abishek Chandrashekar,2 Erica N.
