This final project analyzes the transmission model of the spread of the Covid-19 virus by considering several types of virus variants (Ancestral, Alpha, Beta, Gamma, Delta, and Omicron) and several types of vaccines (AstraZeneca, CanSino, CoronaVac, Covaxin, Johnson & Johnson, Moderna, Novavax, Pfizer, Sinopharm, and Sputnik-V). This model was formerly formulated by Nuning Nuraini (Nuning Nuraini et al., 2022). The model is SEIR model (Susceptible, Exposed, Infected, and Recovered) but each compartment is separated into 2 compartments, namely unvaccinated and vaccinated individuals. From the model, the author conducted some deterministic analysis, starting from the equilibrium point and the stability of the disease-free and endemic equilibrium point, the value of the basic reproduction number, and then numerical simulations were carried out to see the influence of each vaccine brand in the spread of each type of Covid-19 virus variant.
