Some (braindead) people believe that this vaccine causes regressive autism in its patients. These people are mainly followers of the holistic medicine movement.
Coincidentally these people are also severely retarded/ the victim of a surprise icepick lobotomy/someone in a coma/madonna/5 times worse than your average paedophile.
So the next time someone espouses their homeopathic, generally incorrect and totally unscientifically founded views on this subject, you would be totally within your rights to paprecut the worlds "Dr wakeman was paid off to make these wild allegations by a firm specializing in beating the fuck out of any medical malpractice for financial gain" onto their chests.
