Thanks to "Contact Contact" for attempting to respond but the actual location to obtain past immunization records is to use the Washington State Dept. of Health's free MyIR system at https://www.doh.wa.gov/YouandYourFamily/Immunization/ChildProfileHealthPromotion/ForParents/AccessyourFamilysImmunizationInformation -- We encourage you to also try contacting the health care provider where vaccines were given to you as they may still have your records.
