abstract

  • Objectives Vaccination is the most efficient and cost effective method to prevent influenza, reducing morbidity and mortality rates not only for those vaccinated, but also for the entire population by reducing the spread of the virus. In the context of contact network epidemiology, an individual who is located in the center of the network is more likely to become infected. Thus, vaccinating such individuals before others would be more efficient in reducing the influenza burden. Methods We show that immunizing those who have been infected in the previous season, especially before the peak of the disease, can substantially reduce infection rates for a wide range of influenza viruses. Using the Susceptible Infected Recovered (SIR) compartmental model we ran 2,100,000 simulations, each reflecting two successive influenza seasons over a 1.5 million population contact network based on the …
