The Childhood Immunization Schedule is designed to protect children from serious illnesses as early as it is safe and effective to do so. The recommended timing is based on extensive research to maximize safety and effectiveness.
The schedule is developed by the American Academy of Pediatrics (AAP), an organization founded in 1930 that now has approximately 67,000 members, including pediatricians, pediatric medical subspecialists, and pediatric surgical specialists. The AAP is dedicated to promoting the health, safety, and well-being of infants, children, adolescents, and young adults.

You can also visit the School and Child Care Immunizations Information for Families webpage to learn more about vaccine requirements for school and child care in Washington State.
DOH is in the process of developing its own branded childhood immunization schedule, which remains aligned with AAP recommendations. For the time being, we encourage you to refer to the following resources:
