Figure S1 - Mathematical Modeling of Influenza A Virus Dynamics within Swine Farms and the Effects of Vaccination

Summary of the effects of vaccination strategies on the number of infectious animals in the breeding farm, with vaccination occurring when influenza is endemic and circulating in the population (i.e. after an outbreak). In (a), note that the ‘Mass vaccination – homologous’ curve lies along the x axis (as infection is eliminated). In addition, both pre-farrow curves are obscured by the ‘No vaccination’ curve, which is very similar in both cases. In (b), all curves are very similar to the ‘No vaccination’ curve; vaccination does not measurably affect the number of infectious piglets. (EPS)
