Vaccinations/autism

I am really starting to realize that I am a HUGE believer in childhood vaccinations. I mentioned a few posts ago that a large part of it is Simon and the Rotavirus. While doing some personal research on vaccinations and autism I came across this article that I read back in January at my sisters house. It is from Wired magazine, and is a very interesting, informative article. I believe in getting your child vaccinated, I believe in the Rotavirus vaccine, I wish I had known about it a year and a half ago, and I do not believe that autism and vaccinations are related. If anyone can come up with some good scientific research to the contrary, I would love to read it. I am thinking that in the future this is a cause I would really like to get more involved with and would like to be able to spread the word about vaccinations and stop some of the damaging hype/hysteria about autism and vaccines caused by paranoid people who just haven't done research and are basing their opinions on what other paranoid people think instead of scientific research and data. That's my short rant for tonight. To be continued some other time...
If there are any readers who do believe the autism/vaccine link, I would really be curious to know what kind of evidence or information you base your belief on, seriously, this isn't just an attempt to bash, I am very curious to know why people believe what they do. If it's just because Jenny McCarthy said so, or because so-and-so thinks so because their kid got a shot and then started acting weird, or if there is more to it than that.
