Those who are against vaccination do plenty of reading, it is just unfortunately from sources, employing wild circular reasoning, amazingly poor experimental design, deceitful interpretation or general lack of scientific understanding. I understand that people get sucked into these theories, because on the surface they truly seem plausible. However if you scratch at all beyond the surface, or have any legitimate desire to think analytically about what it means to apply the scientific method to test hypotheses these sources fall apart.

Unfortunately the anti-vaccination stance falls in the same pile with all of the other ideas rooted in grand conspiracies and cover-ups. Concocted by those prone to paranoia, and perpetuated by others that enjoy the attention of becoming the spokespeople for a large group of followers eager to regurgitate what ever fulfills their confirmation biases.
