  1. aTrue VE is a set value used in the calculations
  2. bObserved VE is direct VE estimated using the MarketScan® Commercial Database data
  3. cProjected VE is the direct VE calculated in a hypothetical population of 1,000,000 with vaccine coverage of 50%, true VE of 95%, sensitivity of 0.5, specificity of 0.99, and estimated RVGE incidence among unvaccinated children based on the MarketScan® data for each year from 2010 to 2016
