In this paper, we have considered a dynamical model of Chlamydia disease with varying total population size, bilinear incidence rate and pulse vaccination strategy. We have defined two positive numbers \(R_{0}\) and \(R_{1}(\le R_{0})\). It is proved that there exists an infection-free periodic solution which is globally attractive if \(R_{0}<1\) and the disease is permanent if \(R_{1}>1.\) The important mathematical findings for the dynamical behaviour of the Chlamydia disease model are also numerically verified using MATLAB. Finally epidemiological implications of our analytical findings are addressed critically.
