Extended Data Fig. 1: Live virus neutralizing antibody responses to SARS-CoV-2 variants.
From: Immunogenicity of Ad26.COV2.S vaccine against SARS-CoV-2 variants in humans
SARS-CoV-2 live virus neutralizing antibody responses against WA1/2020, B.1.1.7 and B.1.351. Red bars reflect median responses. Dotted lines reflect lower limits of quantitation. Filled squares, placebo–placebo; filled circles, high dose–placebo; open circles, high dose–high dose; filled triangles, low dose–placebo; open triangles, low dose–low dose. n = 25 independent samples (5 placebo recipients, 20 Ad26.COV2.S vaccine recipients).
