Explain about the Pulse vaccination?

How many doses of a given vaccine, administered to what people and on what schedule, permit eradication or control of an infectious disease? Classical models referred just the effects of constant rates of vaccine administration. Inspired in part by the logistical and educational problems denoted by dispersed populations in developing countries, vaccine programs have turned to pulse vaccination strategies in which large cohorts of susceptible children are vaccinated in a period of days to weeks. Mathematical models of pulse vaccination illustrates that in addition to its logistical advantages, pulse vaccination may assist eradicate disease by driving disease for the moment to extremely low levels and by synchronizing epidemics in different populations, permitting for stochastic extinction of disease in the whole population.
