Epidemiology predicted by the mathematical model for seasonal influenza and rubella with no differences between two population groups (black dashed line) and with differences in susceptibility and contact rate for group H (orange region) and group L (navy region) across feasible range of contact rate within social groups (χ = 0.65 – 0.95) and base case values of integration (ξ = 0.15) and susceptibility (Table 1). a Cumulative incidence of influenza over a single outbreak with no vaccination. b Proportion of population infected with rubella by age at endemic equilibrium with no vaccination. c Proportion of all infections acquired in each 5-year age group, with no vaccination. d Cumulative incidence of influenza with 37% vaccine uptake (80% of the critical vaccination threshold (CVT)). e Proportion of population infected with rubella by age with 67% vaccine uptake (80% of the CVT). f Proportion of all infections acquired in each 5-year age group, with 67% vaccine uptake (80% of the CVT)
