Figure 6.

Partial versus full vaccination coverage. Effective reproductive number on day 30 after initial infections are imported ($r_{\mathrm{eff}}^{30}$) as a function of the proportion of people who received at least one dose and the proportion of people who received two doses (everyone received the Pfizer–BioNTech vaccine and the proportions along the top axis are with respect to the eligible population). In all scenarios 20 agents infected with the Omicron variant are inserted into the community. We have clipped the colour scale such that $r_{\mathrm{eff}}^{30}\in$ [0.5, 1.5] to better see the zone near $r_{\mathrm{eff}}^{30}=1$. (a) Eligible population aged $16+$; (b) eligible population aged $12+$. From top left to bottom right, the yellow squares illustrate the progression of the vaccine roll-out in Queensland, starting from 1 August 2021 and proceeding along the first of each month through to January 2022 [56].
