Extended Data Fig. 2: Principal components of genotyped individuals from COV001 and COV002 alongside individuals from 1000 Genomes (1000 G) European, Asian and African populations.

The European cluster is magnified in the inset to demonstrate effective overlap between the majority of self-reported White ChAdOx1 nCoV-19 individuals and the British (from England and Scotland) 1000 G individuals. Red dashed lines represent PC1 and PC2 thresholds to define a specific European cluster.
