Washington State law requires that each child attending school be immunized according to a schedule determined by
the Washington State Board of Health. When registering a child for school, parents and guardians are asked to
provide proof of acquired immunity for vaccine-preventable diseases through a completed Certificate of Immunization
Status (CIS) form. Registration and attendance at school are contingent upon either adequate immunization or
documented exemption from immunization.
Immunization requirements for school attendance may be different than those requirements during an "outbreak"
of actual vaccine preventable disease at school. The local regional health department determines when an outbreak
is occurring and determines any additional requirements needed during the outbreak. For this reason, it is very
important to continue reporting the dates of your child's immunizations since you completed the original CIS
form when you registered your child. Dates can be reported to your child's school office.
The Washington Immunization Information System (IIS) is a statewide registry system for tracking and
storing immunization data. The system is a secure, web-based tool connecting healthcare providers,
schools and people of all ages who receive immunizations. More healthcare providers are recording
immunization data in IIS every year. Your child’s healthcare provider or school secretary may be able
to print out a current CIS form for your child from this registry for you to sign and provide to the school.
Parents and guardians desiring access to their family’s immunization records can sign up for an account
