Effect of Being Vaccinated Against Covid-19 Without Any Other Therapeutic Interventions: A Compartmental Mathematical Model

Abstract

     A mathematical model for covid-19 is formulated, it is based on a compartmental system of nonlinear ordinary differential equations focusing on vaccination and excluding any other interventions hence the proposed mode is divided into eight compartmental classes, namely, susceptible , first dose  the second dose , booster dose vaccinated  exposed  asymptomatic , symptomatic , and recovery . The basic reproduction number  is calculated by the next-generation matrix (NGM) method.  Comparison of the resulting value of  with its corresponding for the general model which includes hospitalized  shows the importance of keeping a bit of healthcare beside vaccinations to get the best results to combat the epidemic.
