Accumulated Zika infections via each transmission route. a through Route 1 (individuals are infected by ZIKV with no prior dengue infection) for the case without vaccination; through Route 1A (individuals are infected by ZIKV either with no prior dengue infection or with prior dengue vaccination) for the case with vaccination; b through Route 2 (individuals are coinfected with Zika and dengue); c through Route 3 (individuals, who were infected with dengue previously and recovered, are subsequently infected with ZIKV); d through all routes. The dash curves denote the number with dengue vaccine while the solid curves are the number without dengue vaccine. Here we fix β_d=0.07, β_z=0.07, κ=2 and P_v=0.3
