My son is in a public elementary school, first grade. We partially immunized him as a baby, but didn't do Hep B, MMR, or any shots since his first year. We have always signed the personal exemption area on the back of the immunization forms for preschool and then also when we enrolled him last year for kindergarten. Nobody has ever said anything to us about it. Today he came home with a form in his backpack stating that they want him up to date in 30 days or he can't attend school. We are not willing to immunize him further. I have a call in to his doctor to request a physician's exemption, but don't know if he will sign one or not. If not, does anybody know if personal exemptions will work in Washington State if you've partially vaccinated, or only if you refuse all immunizations since birth? Any help is very much appreciated. Thanks!
