Yamhill County commissioners vote to require parental consent for teens under 18 to get COVID-19 vaccine Going against state law, commissioners voted 2-1 to require parental consent for any county-affiliated vaccinations of teens ages 15-17. Author: Tim Gordon Updated: 10:23 PM PDT May 20, 2021 MCMINNVILLE, Ore — Before Thursday's board meeting, Commission Chair Mary Starrett convinced the Yamhill County health and human services director to require the consent from parents for teens ages 15-17 getting a coronavirus vaccine. The director, Dr. Lindsey Manfrin, initially went along with the request but then reversed course. Now she’s saying it's not a good decision to require that consent, legally or for teenagers.
