Abstract

The WW model has been used to examine the epidemiological consequences of having a flock of resistant lambs as a result of either selective breeding or vaccination. However, these simulations started with "resistant" sheep rather than simulating the gradual change in immune response that would occur over a number of years in a breeding program.
