(a), (b), (c), and (d) show that administering vaccination on susceptible individuals reduces the number of secondary infections in the carrier and the ill population. (e) and (f) show the optimal control profile of vaccination. Initial conditions S(0) = 700, C(0) = 250, I(0) = 40, and R(0) = 10 and the parameter values π = 100, η = 0.35, ω = 0.2, δ = 0.1, σ = 1, α = 0.2 and θ = 0.0839 were used in this simulation.
