Stability analysis of a general age-dependent vaccination model for a vertically transmitted disease under the proportionate mixing assumption
Faculty of Mathematical Sciences, University of Khartoum Khartoum, Sudan
An SIR epidemic model of a general age-dependent vaccination of a vertically as well as horizontally transmitted disease is investigated when the total population is in steady state. We assume proportionate mixing and age-dependent fertility, mortality and removal rates. We determine the steady states and examine their stabilities.
