Query: Global dynamics of a two-strain flu model with a single vaccination and
  general incidence rate   In this his paper, we studied the global dynamics of a two-strain flu model
with a single-strain vaccine and general incidence rate. Four equilibrium
points were obtained and the global dynamics of the model are completely
determined via suitable lyapunov functions. We illustrate our results by some
numerical simulations.
