Abstract
In the Jan/Feb issue García et al. emphasized that “improper vaccine application and poor biosecurity” have allowed ILT vaccine strain virus to become endemic in many poultry producing areas. With this in mind we invited Dr Chip Garritty of Merial Select to use this forum to challenge the dogma on ILT vaccination. Following a series of long and involved research trials they came up with some really interesting conclusions and take-home messages. The purpose of the research was to provide the poultry industry with scientific data on which to base decisions on how to optimize protection against and possibly eradicate the presence of ILT. The following is an abbreviated version of a presentation given by the author on the truths and myths of ILT vaccination.
