I'm glad this has been ruled on. Blaming vaccines is tantamount to blaming TV or video games exclusively for a child's behavior. There are very likely many complex factors (including genetics) that come into play for behaviors and conditions such as ADHD, autism, and anti-social behaviors.
I wish people would stop focusing on who's to blame (and sue) and rather focus on what's objectively (and empirically) the cause or causes and use those discoveries to formulate a solution or remedy if possible.
On the other hand, autistic children often demonstrate amazing potential using parts of their brain rarely used by "normal" people. Unlocking to secrets to how they dwell primarily in these parts of the brain may help unlock new potential in all people to use their heads far more effectively.
Every challenge is an opportunity in disguise (sometimes a very VERY clever disguise).
