Thank you for your review of the Marek's vaccine! Marek's disease can cause paralysis, blindness, and death in up to 80% of an infected flock. There is no cure for a flock once it has been infected; the only way to prevent the disease is to vaccinate for it within 24 hours of the chick hatching. We do suggest vaccinating against Marek's.
My Pet Chicken offers the vaccination for Marek's disease as an option for our flock keepers since Marek's is the number 1 disease-related killer of chickens and there is no cure for it. The best way to prevent the disease is to vaccinate for it within 24 hours of the chick hatching. We have much more detailed information in our article on the Frequently Asked Questions page which hopefully will help in your understanding of the disease and vaccination: Should I get my birds vaccinated? Of course, if you have additional questions, please let us know. We are always happy to help!
