Figure 3.

Cumulative numbers of COVID-19 infections and deaths by age group. Cumulative numbers of infections (A, C) and deaths (B, D) in the simulation for 150 days are shown by age group. The vaccination coverage (in three colors) and the vaccine efficacy (panels A and B for very effective vaccines; and panels C and D for effective vaccines) were subject to change. The basic reproduction number was set to 5.0. The x-axis denotes the degree of transmission reduction due to nonpharmaceutical intervention restrictions. The y-axis is in a linear scale.
