It's not just chemicals and compounds that should cause concern, but rather, the action of the antigens on the immune system, which can be diverted and left vulnerable to other agencies. Vaccination should be used judiciously. Just as bad as the "anti-vaccination" mentality is the "pro-vaccination" counterpart that considers any vaccination, in any combination, at any time and under any circumstances is beneficial. The veterinary profession (to its great cost, for vaccination is the mainstay of its practitioners' incomes) has adjusted its recommended vaccination protocols for dogs and cats after concluding that many adverse conditions can be caused by over-vaccination, including autoimmune conditions and cancers.
Exactly, top to bottom, except your comment, “vaccination should be used judiciously.”
In the absence of balancing safety, it becomes reckless...rebounding back to your other which echoes my assertion that pro-vaxxers’ histrionics are as bad as the others.
The thimerosal debacle is evidence that without changes in the discipline itself, it may be decades before basic ethics returns to medical research and ensures vaccine safety.
