Sharon Yorks:
Here is a link to the Mareks Vaccine Manufacturer (Pfizer) website: https://animalhealth.pfizer.com/sites/pahweb/US/EN/Conditions/Pages/Marek_Disease_MD.aspx

And here is their telephone number: 855-424-7349 - https://animalhealth.pfizer.com/sites/pahweb/us/en/contact/pages/contactus.aspx

There's a lot of other information on their website, too.

Beth C:
Awesome!! Thanks so much!

Does anyone feel that the Lavender/Self-blue variety is more suseptible to Marek's than other varieties?  I seem to be having a problem with these and my bantam Brahmas this year.

Mike Gilbert:
Clare, I don't know about lavenders as I never raised them.  But my black bantams were always more susceptible than, say the buffs or wheatens.     Since the lavenders are diluted blacks, I would suspect they might be, but then I suppose there is more than one strain of blacks out there too.  Vaccination will take care of about 98% the problems based on my own experience, and I have been vaccinating since 1997.

Birdcrazy:
Mike, I think you are right about the black line being more suseptable to mareks. I bought some unvaccinated Black and Blue Ameraucana chicks 3 years ago. I had never had experience with Mareks desease until then. At about 3 months of age I started losing chicks. I did some reading and diagnosing and they died from classic mareks paralysis. By the time I ended the year, I lost about 70% of the chicks I bought and chicks that I hatched. I was as devestated as my flock was, and about to throw in the towel. I even had about a 10% loss of adult birds. It seemed it really hit the Black and Blue Ameraucana (both LF and bamtam) lines exceptionally hard. Self Blue O. E. bantams, and some Easter Eggers I had raised for several years years with no problems, also were hit hard. My Silver Duckwing and BBR Old English seemed pretty much immune as well as my Black, Blue, Splash, and Silver Laced Wyandotte bantams. I have been vaccinating all day old chicks for the past 2 years ( abt 800) and not lost any to mareks. I have not been brave enough to risk not vaccinating some chicks now for a test as the vaccine is fairly inexpensive and I have to pitch unused mixed vaccine anyway. Much thanks to those who engineered the vaccine!!!!!!!!
