When directly transmitted diseases are modelled assuming an everlasting induced immunity,they are well established formulas to deal with ,which is not true if we include the loss of induced immunity . In general the immunity induced by the disease is ever lasting.We propose a model considering the loss of immunity and presents methods for the estimation of two epidemiological parametres.The force of infection and the basic reproduction ratios.We also analyse the effects of the loss of immunity on the parametres.Based on these results we concluded that reinfection can play an important role in highly vaccinated population.by practising below habits we can increase our immunity power.
