This is patently false and human beings are not chickens. Most human vaccines such as polio or measles produce a sterile immune response. This replicates natural immunity and produces a natural eradication of diseases. In many cases whole diseases have gone extinct from it.This is how the human vaccines work too. That's why we will never eliminate the viruses we vaccinate for. Pertussis, whooping cough, is spread this way.
Additionally, people are not chickens. If a vaccine has a chance of keeping large swaths of human populations alive then it should be used until a better option is available. Chicken genocide happens daily and I'm willing to accept the sacrifices of millions or billions of chickens dying for the sake of a healthier food systems in the future. I refuse to advocate for genocide of humans for a number of reasons and that includes the mass genocide of humans who are not naturally immune to diseases; which the alternative option to trying to keep them alive is to let them die.
Please don't mistake my concern for Mareks leaky vaccine as foolish anti-vaxx rhetoric. Anti-vaxxing for humans is by and large drivel and leads to some horrific conclusions about eugenics in humanity. I base my opinions off of peer reviewed research not feels about chemicals. Please do not use my posts to try to support anti-vaxx rhetoric for humans. I don't agree and think its awful.
