Mercury (thimerosal) exposure has declined significantly since it was eliminated from the single-dose vials of most childhood vaccines, yet autism rates have continued to skyrocket. This has led many to assume that mercury isn’t a problem, and anyone questioning the safety of vaccines is considered to be a hysterical wingnut.However, while mercury use has decreased, the use of aluminum additives has increased! Aluminum, like any other adjuvant, is added to the vaccine in order to boost the host’s immune response to the antigen. The antigen is what your body responds to and makes antibodies against (the virus being injected). By boosting your body’s immune response, the vaccine manufacturer can use a smaller amount of antigen, which makes production less expensive.
