Global map that depicts the assigned antigenic score per country/region each month. The score is representative of the circulating lineages for each month, their potential antigenicity and frequency in that country/region. A dark blue represents a country antigenic score of 0 while red depicts a country antigenic score of 10. Countries/regions with higher antigenic scores have higher frequency circulating lineages that scored higher for potential antigenicity based on the methodology outlined here (Method).

Heatmap with the frequencies of antigenically altered lineages for the previous month. Lineages with an asterisk are significantly altered compared to other circulating lineages with a z-score of greater than or equal to 1. Otherwise the lineages without an asterisk are ordered by frequency with the most frequent at the top of the heatmap. The dark red color indicates a frequency of 1 while the lighter color red represents a lower frequency closer to 0.
