The basic reproduction number was obtained, the stability of the model was analyzed, and the sensitivity analysis was also carried out. Of interest is the numerical simulation of the model where the impacts of contact rate, first and second dose vaccination were studied. The obtained results recommended how to control the corona virus keeping in mind the contact rate and vaccination.</p><p><strong>Keywords</strong>:&nbsp;&nbsp; Covid-19, Double dose Vaccination, Basic Reproduction Number, Global Stability</p> ER -
