The understanding of the interaction between disease dynamics and human behavior is an important and essential point to control infectious . Disease outbreak can be influenced by social distancing and vaccination . In this study, we introduce two compartmental models to derive the epidemic curve and analyze the individual's behavior in spreading and controlling the COVID-19 epidemic . The first model includes Susceptible, Exposed, Infectious, Hospitalized, Recovered and Death compartments and in the second model, we added a new compartment namely, semi-susceptible individuals that are assumed to be more immune than the susceptible . A comparison of the two models shows that the second model provides a better fit to the daily infected cases from Egypt, Belgium, Japan, Nigeria, Italy, and Germany released by WHO . Finally, we added a vaccinated term to the model to predict how vaccination could control the epidemic . The model was applied on the record data from WHO.
