There was a virus that caused chickens to develop cancer and die. They developed a vaccine for it however chickens were still getting the virus and able to spread it. This caused the virus to adapt and become stronger since it was finding resistance against the vaccine. It turns out the virus was much worse against the unvaccinated chickens. This is termed when a vaccine leaks. This is not a troll, poetry, or a nursery rhyme of any type @Jay G. Tate . It was being discussed on the radio this morning and I didn’t catch the HOLE conversation.
