I understand your frustration. I really do. I have wondered this, often. One thing we must realize is that Marek's is a complex Alpha Herpesvirus... To put it into perspective, how many viruses of human beings have we not even developed ANY vaccine for? How many still plague us, despite millions (billions?) spent in research, and being able to communicate with patients (unlike dealing with a sick animal, that can not describe exact symptoms in detail...). Ironically, the research into and development of a vaccine for MDV-1 Chicken Marek's Herpesvirus led to the research that developed the first human vaccine against HPV (Human Papilomavirus), which is cervical cancer. Like Marek's virus which can cause lethal cancer within our birds, HPV is a virus that causes cancers in humans. In fact, some of the herpesvirus family is known occasionally to cause cancer in humans, too. Here's some reading: http://www.faseb.org/portals/2/pdfs/opa/2008/HPV.pdf Anyway, my point is... what we have is surprisingly good. Not great, but... we can't say the same for some human disease. Oh no, I'm so sorry. This is just the worst thing to have to do. My heart breaks for you.
