Maddie and Olivia Meylor were diagnosed with premature ovarian failure in 2007, when they were teenagers. They started menopause decades early.
"We were devastated," said Joen Meylor, the girls' mother. "It's rare at their age and it's very rare that two sisters would have premature ovarian failure."
The sisters went through the same genetic testing, looking for answers. They say all roads led back to that doctor's visit in 2007.
"I realized it was the Gardasil vaccine," said Joen Meylor.
