Extended Data Fig. 9: CD4+ TCRβ repertoire analysis.
From: Immunogenicity of Ad26.COV2.S vaccine against SARS-CoV-2 variants in humans
CD4+ T cell breadth and depth by TCRβ sequencing on day 57. Red bars reflect median responses. 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; plus signs, convalescent samples. n = 32 independent samples (8 SARS-CoV-2 convalescent individuals, 5 placebo recipients, 19 Ad26.COV2.S vaccine recipients).
