Have you ever gotten a vaccination? If so, do you remember being told what the ingredients were or what side effects could possible occur? In many cases, the answer to that is probably no because some doctors tell patients very little about the vaccine as they may not know what could happen post administration. At any rate, vaccines contain an adjuvant, which is used to act as a stimulant and one of the most common adjuvant is the chemical compound aluminum. Aluminum adjuvants have been used in a wide variety of vaccines for decades, however, aluminum is a non-essential metal when it comes to human function and it is a known neurotoxin.
