My daughter began having severe headaches and dizzy spells after her sequence of Gardasil shots in late 2007. We've had her to the family doctor, a neurologist, an ENT, and multiple Emergency Room visits. All the tests (CT Scans, MRI's, blood work) have come back normal. While we're thankful for that, we're left frustrated and scared. I was assured by her pediatrician and our OB/GYN that this vaccine was completely safe. I am now beginning to have my doubts, and am scared to death of what may come next; or that she's going to suffer like this indefinitely.
