Qualitative analysis found out the positive equilibrium points being possible in addition to the infection-free equilibrium point. The stability and bifurcation analysis of this equilibrium points was performed. Our mathematical model used Holling type-2 response is a useful tool that can be utilized in predicting the timing and expansion of infection and possible reinfection processes in an individual as depend on the parameters used. Also, the results os analysis was supported by numerical simulations. CR - André, J.B., Gandon, S., Vaccination, within-host dynamics, and virulence evolution, Evolution , 60 (1), 13-23, 2006.
