Fig. 4

Cross section of Fig. 2. Top row represents simulations with 5 years of shingles vaccine immunity and the bottom row represents simulations with lifetime shingles vaccine immunity. Each column visualizes vaccination impact after 25 (left), 50 (middle left), 75 (middle right), and 100 (right) years. X-axes represent the shingles vaccination coverage, while the y-axes represents the change in shingles cases from the null vaccination simulation. Colors represent chickenpox vaccination coverage with a gradient from no vaccination (yellow) to fully vaccinated (dark red). Dotted line at 0 identifies where there would be an increase (above the line) or decrease (below the line) in shingles cases compared to the simulation lacking vaccination
