Based on the limited set of reactions I've seen so far (for instance, http://www.autismweb.com/forum/viewtopic.php?f=6&t=23104 http://www.autismweb.com/forum/viewtopic.php?f=6&t=23104)? No. This won't change a damn thing. When you're that committed to a cause, every scientific result that comes out against your cause is easy to dismiss as either wrong, a deliberate lie, incomplete, not 100% proof, etc. This is especially troublesome in areas where the True Believers invert the burden of proof: rather than asking for proof that vaccines cause autism, they'd only be satisfied with proof that they don't, which is a much more difficult task (and don't get me wrong - I have no doubt whatsoever that even if rock solid proof was offered, they'd still reject it outright).
