  The dynamics of a SIVR model with power relationship incidence rates $(\beta
I^p S^q)$ is investigated. It is assumed an individual can be susceptible after
receiving the first dose of the vaccine, hence a second dose is required to
attain permanent immunity. The steady states conditions of the disease-free
equilibrium and the endemic equilibrium are critically presented. Numerical
simulations are carried out to determine the impact of the exponential
parameters $(p;q)$ on infection.
