Do you think autism is caused by vaccines?

My son is 16 years old and has autism. He is highly functional but still has his outbursts.
Update: I know how to deal with the autism. In fact, he is very smart but he freaks out when he is around people. I have been watching the news and wondering if the vaccine he recieved may have contributed to it. My own opinion, I think it could be possible because mercury is poison!! But I wanted different views on it
