Cumulative incidence at four different levels of vaccination coverage: 94, 95, 98, and 99%, including nonaggregated vaccination data (block-level) resolution to tract level (4-cell) resolution, to neighborhood (16 cell), and, finally, quadrant-level (64 cells) shows the reduction in estimated case burden as aggregation increases, a pattern that holds true across all levels of vaccination.
