Fig. 8From: A conceptual model for optimizing vaccine coverage to reduce vector-borne infections in the presence of antibody-dependent enhancementCritical and optimal dengue vaccine coverage rates under four special cases. The solid and dash curves represent the changing relationship of the critical and optimal values of dengue vaccine coverage rate with respect to the basic reproduction number for dengue Rd, respectively. Here the antibody-dependent enhancement rate is κ=2Back to article page
