nAbs against RSV clinical isolates. GMFIs are shown from baseline to day 29 in nAbs against RSV A and B clinical isolates for participants receiving the HD/HD combination regimen (n = 24). For each isolate, A and B denote the RSV subtype, and the 2-digit number afterward denotes the year from which each strain was isolated. Ad26, adenovector 26; GMFI, geometric mean fold increase; HD, high dose; nAb, neutralizing antibody; preF, prefusion conformation-stabilized RSV F protein; RSV, respiratory syncytial virus. aA combination injection of Ad26.RSV.preF and recombinant RSV preF protein at the specified dosages. bInjections given in opposite arms.
