Drinking diet coke can cause cancer, leading a generally unhealthy lifestyle can cause cancer, walking down the road can cause cancer, everything causes cancer these days, aside from the obvious ones like smoking. Cancer is an uncontrolled division of cells, it can be triggered by any mutagen that moves repressor genes further away from oncogenes. We live in a stew of mutation-causing crap, what more is to be expected? However, mutation is also nature's way of helping the evolutionary process along. The idea of exposing one's self to potentially unneccessary vaccinations is merely a stop-gap measure. Some illnesses (read mutations) even serve a positive purpose (such as people afflicted with sickle-cell anemia having a natural protection from maleria). Not saying it's nice that people die from stuff like that, but the more we mess with mother nature, the more nasty ways she finds to mess back.
