Finally someone gets this...
(I brought this up several times in the past).
I think eradicating populations of anything rather than quarantine followed with breeding the survivors is odd too.
Posting blind here. Longtime lurker. But anyway, I am connected with that august organization in the City of Evil, IYKWIM. Your information appears mostly correct, except that mortality would be around 70% for unvaccinated poultry infected with Marek’s Disease. Marek’s is caused by a virus. And some folks are trying to breed their flocks back to the decades old original low death rates without using the vaccinations. Not sure how that will turn out. Pharma wants to keep their sales of vaccinations going. With that said, yes, the Mareks vaccine is a ‘leaky’ vaccine, just as the Covid vaccine is.
wow
