Dear Health Care Professionals and Partners,

Today, January 20th 2023, the Washington State Immunization Information System (IIS) updated the human papillomavirus (HPV) forecast to start at age nine. This change signals an important step in increasing HPV vaccination coverage across the state of Washington.

IIS Resource

This guide gives a visual representation of how this change is presented in the IIS. There are no major differences in the IIS from a user and technical perspective other than the age of the vaccine forecast has changed to nine. HPV vaccines do not need to be entered differently into the IIS than before this forecast update.
