There is no risk-free path in life, and I say this as the parent of a child who developed epilepsy 5 days after a MMR. Our high school son, with our help, weighed all of the available information and decided to take Gardasil. For our family the benefits outweighed the risks. That said, we do what we can to limit exposure that has no benefit, i.e. do not use aluminum pans (cast iron only) and do our best to eat organic, clean food.
