Interpretive Summary:

Technical Abstract: Current Marek’s Disease vaccines are efficient at preventing disease. However, vaccination can reduce but not completely eliminate virus shedding. Our hypothesis is that an efficient vaccine will result in fewer viruses being shed. To test this hypothesis, we developed a real-time PCR to measure Marek’s disease virus (MDV) in dander shed by infected chickens. We will report on our findings comparing the amount of MDV shed in the dander of birds vaccinated with a good vaccine, to the amount of virus shed in birds vaccinated with a poor vaccine.
