I want to respect yours and others who view immunizations with suspicion, but I do see a fascinating similarity between the tactics of the FARMS/FAIR crowd and those groups opposing immunization. Both start with a set of apriori beliefs and then, working backward, select, filter, and reinterpret data to support their starting beliefs.
In FARMS folks have had to back off the continent-wide locations for the Book of Mormon peoples - marking them down to a Limited Geography hypothesis. The trend is toward an ever decreasing scope for the Lamanite/Nephite peoples. What's next? The "No Geography" hypothesis?
Similarly, in decades past virtually every ailment known to man has at one time or another been blamed on vaccines. Twenty years ago Harris Coulter's "A shot in the dark" blamed all kinds of neurological disorders on the DPT vaccine. A few years later Viera Scheibner's ".Medical Assault." book blamed SIDS on vaccines. Then the rise of the AIDS epidemic was blamed on polio vaccines.
All of these issues have largely subsided as masses of additional data have overwhelmingly discounted them. But much as FARMS bounces from one desperate exercise in desperation to the next so does the 'anti-vaccine movement' (AVM) bounce from one manufactured crisis to the next. With a smattering of semi-medical lingo, a generous helping of unsupported dark conspiracy theorizing, then mix in natural parental concern, and all the ingredients are in place for the AVM to exist.
More specifically: the NVIP program pays claims for purported injuries, but this by itself does not prove or validate any specific claim. The government indemnifies vaccine manufacturers against lawsuits and further reimburses much of the research costs for vaccines as a means to keep the vaccine programs alive. Without this the manufacturers would have dropped vaccine production decades ago. In a recent shareholder report Smith/Kline, manufacturer of many vaccines, reported only around 5% of their revenues came from vaccines. Compared to the market for other much more costly drugs the ROI for vaccines is just not worth it by itself.
The 'research' listed at
http://www.tacanow.org was decidedly unimpressive, and in fact typifies the typical AVM approach. The author submits his/her interpretation to out-of-context snippets from of various studies. The interpretation is pre-determined in the best FARMS fashion and typically has no association to the central question: does thimerosol cause autism? One cannot determine the answer from the materials given.
The AVM groups, again in typical FARMS fashion, steadfastly ignore the mountain of evidence that the increase in autism diagnoses are largely the result of changes in diagnostic criteria and awareness. While some contribution from vaccines cannot be totalluy ruled out, it's clear that genetics play a major rule in the manifestation of autism:

http://www.ncbi.nlm.nih.gov/pubmed/21458558Fatty acid profiles may well be a factor:
http://www.ncbi.nlm.nih.gov/pubmed/21510882The point of all this is that the causes of autism are likely multifactorial, with genetics likely predominating. The AVM crowd generally ignores any of these other contributing factors that have good evidence behind them. They choose instead to focus almost entirely on supposed vaccine injury. This despite the fact the thimerosol compounds were eliminated years ago from typical childhood vaccines - and yet the incidence of autism remains high.
http://www.sciencebasedmedicine.org/?p=14Wakefield? Clearly, at least to me, the man had his own disreputable agendas including huge hidden conflicts of interest, deception, unethical handling of study subjects. You can bet that if his study outcomes had come out different the AVM crowd would have heaped him with ridicule. But because, and only because, his dubious findings fit the AVM crowds' previous agenda he has become their hero.
