Abstract
In this paper, we extend a mathematical model on the impact of vaccination and treatment in controlling the spread of Hepatitis B Virus with infective migrants. Finally, we transform the model into proportions where we investigate and prove a theorem on the existence, uniqueness and positivity of the solution of the governing model in a positive invariant region.
