I am objecting to this one.
Conspiracy theories against vaccines are quite vogue, all constructed by people uneducated on the science. In this case, it is meant to generate transhumanism, whatever that is.
Sometimes antagens, an invasive foreign agent, fails to illicit a proper immune response or prolonged exposure can be overtly taxing on the body. Some responses can be fatal.
It was discovered that immune systems after surviving a particular infestation was primed to create antibodies. By introducing inert antagens from a certain disease agent prior to infestation, the immune system is triggered to produce particular antibodies that help ward off that disease (or decrease it's severity ). That is the merits of vaccinations.
It doesn't change a person's DNA. Despite the claims, there is no evidence it triggers autism. There are, of course, allergic risks that can be discussed with your doctor.
To imply there is a sinister motive is dubious and sinister when unfounded.
