Patient Eligibility

The Washington State Adult Vaccine Program (AVP) provides vaccine to participating provider locations for uninsured adults 19 years of age and older. However, COVID-19 vaccine for adults 19 years and older can be administered to both uninsured and underinsured patients. Underinsured is defined as individuals without cost-free coverage for COVID-19 vaccines. Medicaid and Medicare enrolled patients aren’t eligible to receive AVP vaccines. COVID-19 vaccines are fully covered by both Medicaid and Medicare.

*Underinsured includes individuals without cost-free coverage for COVID-19 vaccines

Eligibility Screening and Documentation

All providers participating in the Adult Vaccine Program are required to confirm the patient’s age and to screen and document each patient’s eligibility status. Status screening consists of asking and documenting the adult’s eligibility status at every immunization visit prior to vaccine administration. 

Screening and documentation may be completed by:

• Patient Eligibility Screening Form (PDF)
• Electronically in the patient’s medical record
• The Washington State Immunization Information System (IIS)
