Autism treatment

This is Hannah.  She is 18 and has Autism.  In this picture she was participating in a Special Olympics meet.  Her long time Aide at her side.  She was diagnosed in late 2002.  I (her mother) am trying to raise money for Stem Cell therapy.  Insurance will not pay for it.  I have located a clinic within our state and not too far from where we are.  It could help her, but would not cause further regression or harm her, but could help her to progress forward.  She was born full term and no issues.  Walking, talking, interacting and all until her last round of vaccinations when she received multiple vaccines in many different shots.  Then slowly she went away...no immediate reaction she just stopped her words, eye contact, and went into her own world.  By the time we found out there was a vaccine injury court the statute of limitations had expired and we could not file a case.  I have been reading a lot about theses treatments.  There is a clinic in Panama, but it costs twice as much.  There is no way I could get her on a plane.  If you can help with anything that would be great.  If you post your name I hope to pay you back.  It might take a little time though...The clinic has an opening in May and two in June.
