Haven't felt well since i received gardasil hpv vaccine three years ago. what could be wrong?

Not the vaccine: Gardasil is one of our most extensivley studied vaccines. In blinded, controlled trials (meaning the recipeints of a shot didn't kbnow if it was the vaccine or a placebo) involving tens of thousans of patients, the same percentages inthe placebo and vaccine recipient groups got symptoms like you describe. Be careful when trying to ascribe cause and effect.
