The Vaccine Book: Making the Right Decision for Your Child. “It’s like, here’s your birth certificate, and here’s when your mom was crazy for a few years,” she says. For a few years, Oyakawa, an occupational therapist, was an anti-vaxxer. Oyakawa vaccinated her first four children according to the routine schedule. But the birth of her fourth child was traumatic; she felt the doctors and nurses didn’t listen to her. “That kick-started me being very skeptical of the medical establishment,” she says. With her next child, Oyakawa opted for a home birth, with the help of a midwife. In the process, she began to meet other “crunchy” parents, she says, including those who were opposed to vaccines. For a time, the Oyakawas were uninsured. Slowly, and then all at once, Oyakawa stopped going to the pediatrician and stopped vaccinating her children, including her new baby.
