On The Application of Homotopy Perturbation Method in Simulating the Effect of Double Dose Vaccination on a Mathematical Model of Covid-19 Transmission Dynamics

Abstract

In this research, the impact of first and second dose vaccination in a mathematical model of COVID-19 transmission dynamics with two vaccination classes is investigated. The homotopy perturbation method is applied to obtain the approximate solution of the mathematical model. The impact of the first and second dose vaccinations were analyzed on the susceptible and exposed classes. The results of the analysis reveal that the second dose vaccination strategy is important to control the spread of the COVID-19 virus which is endangering the global existence of human population.
