ABSTRACT: Vaccination strategies are designed and applied to
control or eradicate an infection from the population. This paper studies three
different vaccination strategies used worldwide for many infectious diseases including
childhood diseases. These strategies are the conventional constant vaccination
strategy, the periodic step (pulse) vaccination strategy and finally the mixed
vaccination strategy of both the constant and the periodic one. Simulation of
the different vaccination programs is conducted using three parameter sets of
measles, chickenpox and rubella. The Poincaré section is playing as a filter of
our simulation results to show a wide range of possible behavior of our model.
Critical vaccination level is been estimated from the results to prevent severe
epidemics.
