Table 4.

Four Vaccine Delivery Strategies Under 20% Vaccination Coverage

Scenarios	Attack rate	Durations
	%, median [1st, 3rd quartile]	Days, median [1st, 3rd quartile]
Scenario 3: random strategy	45.36 [45.04, 45.78]	131 [121, 163]
Scenario 4: age strategy	44.07 [43.26, 44.55]	146 [132, 159]
Scenario 5: space strategy	39.44 [38.57, 39.94]	154 [145, 171]
Scenario 6: space & age strategy	37.66 [37.12, 38.42]	175 [152, 197]

Note. On the basis of Scenario 2 (base scenario), vaccine intervention measures are implemented, in which some individuals are selected for vaccination. Four strategies of vaccine distribution are evaluated (scenarios 3–6). Each strategy was simulated for 100 times. The median and quartiles values of 100 simulations were shown.
