The idea of a “leaky vaccine”\u00a0does exist. But as proof, they point to\u00a0Marek’s disease<\/a>\u00a0in chickens. In that case, the virus changed, causing a stronger version that could make unvaccinated chickens sicker. But this has only happened with Marek’s disease, not with other diseases. Even with this “leaky vaccine,” vaccination greatly reduced how much the disease spread and how many chickens got sick. Because of vaccines, chicken deaths from Marek’s disease dropped by 99% from 1970 to 2006.<\/p>\n

Another incorrect claim is that vaccines turn birds into mutation factories. Viruses naturally change or mutate over time.\u00a0But most mutations happen when a lot of sick animals spread the virus. Vaccines actually slow down virus spread, making it harder\u2014not easier\u2014for new mutations to form.<\/p>\n

He also claims that chickens would gain natural immunity if they were allowed to catch bird flu. The problem with this idea is that flu viruses\u00a0mutate<\/a>\u00a0very quickly. Also, immunity against one type of flu virus doesn’t always protect against other types.<\/p>\n

Scientists\u00a0around the world<\/a>\u00a0agree that vaccinating poultry safely prevents bird flu outbreaks. It also protects farms and reduces the chance that bird flu might spread from birds to people. Vaccines are a safe and effective way to control disease, protect animals, and keep food supplies stable.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
