Heatmap with the frequencies of the selected potential variants of interest (pVOIs) for the previous month that have an assigned antigenic score above the predetermined threshold (3.85). The lineages are ordered from highest, top of the heatmap, to lowest frequency, bottom of the heatmap. The dark red color indicates a frequency of 1 while the lighter color red represents a lower frequency closer to 0. For further information about the SARS-CoV-2 lineage names, which follow the Pangolin nomenclature, see the FAQ.
