Stability for a TB Model with Impulsive Vaccination

An impulsive vaccination strategy to eradicate tuberculosis (TB) is studied by SEIV epidemic model. Since the infection age is an important feature of tuberculosis progression, the infection age is incorporated into the model. The condition for the globally asymptotic stability of the solution is obtained. The condition shows that large enough impulsive vaccination proportion and relatively small impulsive period can lead to the eradication of TB.
