Oregon Yellow Fever Certification and Application Information

Uniform Stamp and Yellow Fever Center Requests

Many countries require specific travel immunizations for visitors. Providers interested in giving these travel vaccines need to apply for a Uniform Stamp.

The Uniform Stamp allows the authorized provider to officially sign the traveler's International Certificate of Vaccination. This Certificate records the vaccinations received and the signature validates this record. The Yellow Fever Center Certification allows the authorized provider(s) to actually purchase and administer the Yellow Fever vaccine.

This training is required, and participants can earn two CEU credits upon completion.

Who can apply:

  • Physicians
  • Physician's Assistant
  • Nurse Practitioner (with prescription-writing privileges)
  • Certified Immunizing Pharmacist
  • Naturopathic Providers

How to apply:

  1. Complete the application(s) available for download on this page below. If unable to download, please call the Immunization Program at 971-673-0300 for a copy.
  2. Applications must be completed in full, and may be faxed, or mailed to the address below. Any applications with missing or incomplete information will be returned to the applicant.
    Please note that Certified Immunization Pharmacists applying for either the Uniform Stamp, or to qualify as a Yellow Fever Vaccination Center must include a copy of their certification of completion of an approved pharmacy-based travel course (see application for details).
  3. Oregon, as well as the CDC, have developed a web-based registry of all authorized yellow fever vaccination clinics. It is very important that this information remain up to date, as travelers will be using the information on these sites to locate vaccine providers in their area.
  4. Continued possession of the stamp, and continued need for its possession will be re-established regularly by completing a questionnaire from State Public Health Division. Completion of this questionnaire is required.
  5. If you move/change address or practice, you must notify State Public Health Division immediately at:

  • Uniform Stamp Agreement (pdf)
    The Uniform Stamp certification alone is to officially document on a patient's International Certificate of Vaccination that the travel vaccinations were given. The stamp can only be used by the provider it is assigned to and cannot be loaned to another person.
  • Yellow Fever Vaccination Center Agreement (pdf)
    The stamp holder can legally administer the Yellow Fever vaccination after he/she completes an application for Yellow Fever Center certification and receives confirmation paperwork from the Immunization Program. Yellow Fever Center certification can be requested at the same time Uniform Stamp certification is sought, or at a later date if the provider already is a Uniform Stamp holder. The application for Yellow Fever Center certification will be processed once the applicant has been approved for Uniform Stamp certification.
