Kira Hughes in Columbus, Ohio

"I wish I'd never vaccinated," this mother tells Polly Tommey. And she is not the only parent who regrets this decision. Kira, her daughter, experienced "extreme pain" after immunization, which soon developed into to symptoms "from head to toe" such as migraines, hair loss, muscle soreness and heart issues. She was told it was "all in her head" — a result of stress. They were not convinced, however, and continued to voice their concerns about the shots to medical professionals, but "they just dismissed it."
