Yes. There are many ways that metal can get into your body, especially depending on how efficient (or inefficient) your body is at getting rid of the metal. Metal that is easily excreted by one person may cause major problems in another person.
Some other ways that metal can get into one's body besides vaccines and Amalgams are drinking water, eating fish and tattoos. My health took a major turn for the worse a couple of years ago after getting a decent-sized tattoo. Of course that was before I had any idea that metal was what was making me sick.
