The Simulation Result When R ₀ = 2, 3 and 4 in Scenario 1

Scenarios	${\mathit{R}}_0$	Simulated herd immunity	Classical herd immunity	Durations
		%, median [1st, 3rd quartile] *	%, 1‐1/${\mathit{R}}_0$	Days, median [1st, 3rd quartile] *
Scenario 1	2	50.23 [49.67, 50.70]	50.00	150 [132, 170]
Scenario 1	3	66.11 [65.70, 66.58]	66.67	128 [120, 143]
Scenario 1	4	74.69 [74.30, 75.25]	75.00	127 [115, 139]

Note. Scenario 1 simulates a completely natural transmission without any intervention measures, assuming that all agents are equally susceptible, and equally infectious. Sensitivity analysis are implemented under different $R_0$ assumptions. Each $R_0$ hypothesis ran 100 simulations to balance the stochastic effect. The median and quartiles values of 100 simulations were included.
