Global map that depicts the assigned antigenic score for European countries/regions in the previous month. The score is representative of the circulating lineages in the previous 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).
