In addition to that, there have been some recent studies on Polysorbate 80, which is an emulsifier that is put in a lot of processed foods, that has been shown to change the flora in the gut possibly leading to IBS, Crohn’s disease, etc. These studies have been in rats, by the way, so there’s no telling whether they have the same effect on humans. But, I know of at least 1 vaccine that has Polysorbate 80 in it.
Add to that the undeniable fact that vaccination weakens the immune system while it's being challenged, which can lead to any number of illnesses worse than what's being vaccinated for.
Bottom line is that vaccinations are harmful primarily because they do what they're supposed to do ... counterintuitive as that may seem.
