Members sit on the Vaccine Advisory Committee (VAC) for a three-year term with the option to extend one more term, for a total of six years. The chair reserves the right to reappoint members for service exceeding six years if it is determined that doing so is in the best interest of the committee and is mutually agreed upon by the appointing organization and member.
Whenever possible, terms will be staggered for organizations and entities that have multiple members on the VAC to avoid multiple representatives leaving their positions simultaneously.
Additionally, two other state agencies have seats: the Washington State Health Care Authority (HCA) and the Office of Superintendent of Public Instruction (OSPI). The Washington State Chief Science Officer, who chairs the committee, appoints consultants representing healthcare providers in pediatrics, obstetrics, and for connecting to the Washington State Vaccine Association (WVA). Consultants do not have defined terms of membership.
