Abstract
The Poliomyelitis is an acute infection that has not eradicated worldwide. There are two types of vaccines for prevention: the live attenuated virus (OPV) and the inactivated polio virus (IPV). In Colombia, the poliomyelitis eradication strategy has been implemented, changing the OPV for the IPV, following the recommendations of the World Health Organization (WHO). This paper presents a mathematical model that describes the dynamics of the infection in a population where the two types of vaccines are implemented. The population is divided into two age groups, considering migratory effects between them, the interactions are described using Michaelis-Menten functions. Different vaccination scenarios are simulated and analysed in order to establish the convenience of replacing OPV vaccination with IPV.
