A senate committee hearing today on autism research and ways to help families pay for therapies not covered by insurance.
One polarizing topic on today's agenda -- the issue over whether vaccines cause or contribute to autism.
One official cited 16 studies involving hundreds of thousands of children.
None found any evidence linking the two.
But the lack of any definitive cause gives many parents pause before they allow their children to be vaccinated.
Doctors say this often leads to a disconnect between parents and pediatricians.
All agreed more research -- and more money -- is needed to help parents and doctors treat kids effectively and wade through conflicting information.
