Fig. 1: Diversity of circulating SARS-CoV-2 lineages.
From: Quantifying how single dose Ad26.COV2.S vaccine efficacy depends on Spike sequence features
a The distribution of SARS-CoV-2 lineages of COVID-19 primary endpoints. The number of lineage sequences identified each month is shown for vaccine and placebo participants. b The distribution of variant sequences identified in Latin America as a function of their Spike Hamming distance from the vaccine insert. Lineages are color-coded as follows: Alpha, teal; Beta, pink; Delta, red; Epsilon, dark blue; Gamma, mustard; Iota, light blue; Lambda, pink; Mu, light green; Zeta, purple; and Reference, lavender. vp viral particles.
