MADISON, Wis. (AP) – Two Mount Horeb sisters have filed a federal claim, saying a cervical cancer vaccine shut down their ovaries. The Wisconsin State Journal reports 20-year-old Madelyne Meylor and 19-year-old Olivia Meylor claim their condition came from the Gardasil vaccine against human papillomavirus, or HPV.  In a statement, the vaccine’s maker, Merck and Co., says evidence doesn’t support a relationship between the condition and vaccine. The Centers for Disease Control and the Food and Drug Administration say the vaccine is safe. Their attorney, Mark Krueger, says it’s the first allegation the vaccine caused the condition to reach a hearing through the National Vaccine Injury Compensation Program. That’s a special court established to evaluate claims of harm from vaccines. The case is scheduled for a hearing Thursday and Friday in Washington, D.C.
