The fastest way to get your immunization records in Colorado is through the Colorado Immunization Information System (CIIS) Public Portal, which lets you view and print an official record online in minutes.1Colorado Department of Public Health and Environment. Get a Copy of Your Immunization Records from CIIS If the CIIS record is incomplete, you can fill the gaps by requesting records from the doctors, pharmacies, or schools where the shots were actually given. When records simply can’t be found, a titer test or revaccination will rebuild your documentation.
Start With the CIIS Public Portal
CIIS is the statewide immunization registry maintained by the Colorado Department of Public Health and Environment (CDPHE).2Justia. Colorado Code 25-4-2403 – Department of Public Health and Environment – Powers and Duties – Immunization Tracking System – Rules – Definitions Providers across Colorado report vaccinations to CIIS, so for most people it already holds a usable history in one place. You can pull your own record, and a parent or legal guardian can pull records for a minor child.1Colorado Department of Public Health and Environment. Get a Copy of Your Immunization Records from CIIS
Have your full name, date of birth, and current address ready when you log in to the Public Portal, since the system uses that information to match you to the right record. A COVID-19 vaccination record can also be requested through the portal or the myColorado mobile app.3Colorado Department of Public Health and Environment. Information About CIIS and Immunization Records for the General Public
One caveat matters before you panic over a short printout: CIIS only contains shots that providers actually reported to the system. Doses given by a non-reporting provider, received in another state before you moved to Colorado, or administered in the 1980s or 1990s before the registry existed may not appear. A sparse CIIS record doesn’t necessarily mean you missed vaccines.
If the portal gives you trouble or your record looks wrong, CDPHE’s immunization staff can help by phone at (303) 692-2420 or by email at cdphe.ciis@state.co.us.4Colorado Department of Public Health and Environment. Immunization Contacts
Request Records From Your Healthcare Provider
When CIIS has gaps, the doctor’s office, clinic, or pharmacy that actually gave you the shots is usually the best backup. Providers keep their own medical records, and those files often include doses that never made it to CIIS. This works best when most of your care has come from one or two places you can remember.
Call and ask specifically for a copy of your immunization record. You’ll need your full name, date of birth, and the approximate dates you were a patient. Many offices will also ask for a photo ID and a signed medical records release before releasing anything. Under federal HIPAA rules, a provider must respond to your request within 30 calendar days, with one possible 30-day extension if the records are archived offsite.5U.S. Department of Health and Human Services. Individuals’ Right Under HIPAA to Access Their Health Information A simple immunization printout usually comes back much faster.
Colorado law allows providers to charge HIPAA-compliant fees for copying medical records.6Justia. Colorado Code 25-1-802 – Patient Records in Custody of Health-Care Professionals For an electronic copy, federal rules cap the flat fee at $6.50 per request, covering labor, supplies, and postage.7U.S. Department of Health and Human Services. Is $6.50 the Maximum Amount That Can Be Charged Paper copies can cost more depending on page count, but a provider can’t charge you to simply view your records in the office. For an immunization history, you’re usually looking at a page or two.
Try Schools and Childcare Facilities
Schools and licensed childcare facilities in Colorado collect immunization documentation for every enrolled child, which makes them a useful source for pediatric records in particular. Call the school nurse or the childcare administrative office and ask for a copy of the immunization records on file. You’ll typically need the child’s full name, date of birth, and the years of attendance, and some facilities will require a signed release.
School records aren’t comprehensive. They only reflect what was reported to the school during enrollment, so shots given before the child enrolled or after they left won’t appear. Even so, for piecing together a partial childhood history, they can fill gaps that neither CIIS nor an old pediatrician’s office can cover, especially when the original clinic has closed.
Military and VA Records
Military immunizations don’t flow through CIIS, so service members and veterans use separate channels.
Veterans enrolled in VA health care can find, review, print, and download vaccine records through the My HealtheVet portal on VA.gov. You have to be registered as a patient at a VA health facility to use it. For portal help, VA support is available at 877-327-0022, Monday through Friday, 8:00 a.m. to 8:00 p.m. ET.8Veterans Affairs. Review Medical Records Online
Former service members not enrolled in VA care can request military medical records by submitting Standard Form 180 (SF-180) to the National Personnel Records Center in St. Louis. The form is available on the GSA website or by request from the Records Center, a local VA office, or a veterans service organization. If you’re asking specifically for medical or clinical treatment records, additional details may be required on the form. Completed forms go to the National Personnel Records Center, 1 Archives Drive, St. Louis, MO 63138, or by fax to 314-801-9195.9National Archives. Request Military Personnel Records Using Standard Form 180 Processing times vary, sometimes significantly.
If You Need Records for International Travel
For most international destinations, a printout from CIIS or your provider is enough. The exception is yellow fever vaccination, which must be documented on an International Certificate of Vaccination or Prophylaxis (ICVP), commonly called the yellow card. This is the only internationally recognized proof of yellow fever vaccination, and some countries will deny entry, quarantine you, or require revaccination on the spot if you can’t produce one.10Centers for Disease Control and Prevention. International Certificate of Vaccination or Prophylaxis (ICVP)
The yellow card is issued and stamped by the clinic that administers the vaccine, your name must match your passport exactly, and the card becomes valid 10 days after vaccination. Despite any printed expiration on the card, yellow fever vaccinations are now considered valid for life. The CDC does not issue these cards or keep copies of individual vaccination records. If you lose yours, contact the clinic that originally gave the shot; if that clinic is gone, contact the state health department where the vaccine was given to ask whether it keeps individual records.10Centers for Disease Control and Prevention.

When Records Are Incomplete or Missing
Records disappear more often than people expect. Clinics close or merge, families move across states, and paper files from decades ago sometimes just vanish. If you’ve checked CIIS, called every provider you can remember, and asked former schools, you still have two practical options.
The first is a titer test, a blood test that measures antibody levels for specific diseases. Sufficient antibodies serve as documented proof of immunity, regardless of whether the original vaccination record ever surfaces. Single-disease titers (for hepatitis B or varicella, for example) typically run $49 to $60 out of pocket, while broader panels covering multiple diseases range from roughly $95 to $300 depending on what’s included. Insurance may cover titers when medically necessary, so check with your plan first.
The second option is revaccination. If a titer shows low antibody levels, or you’d rather skip the blood work, a doctor can give the vaccines again. An extra dose of most vaccines is safe and creates a fresh, documented record going forward. Your provider will report the new doses to CIIS, which makes future retrieval straightforward.
Either way, work with a current provider who can review your partial records, order any tests, and build a plan to close the gaps. Start before a deadline hits. School enrollment, job onboarding, and travel timelines rarely leave room for weeks of back-and-forth with old clinics.
If You Previously Opted Out of CIIS
Colorado law lets you exclude your immunization information from CIIS, and parents or legal guardians can opt out on behalf of a minor.11Colorado Department of Public Health and Environment. CIIS Opt-Out and Rescind Opt-Out Procedures If you opted out before and now need the records for school, work, or travel, you can rescind the opt-out through CDPHE. While you’re opted out, your data won’t be available through the Public Portal, so provider offices and your own paper copies become your main sources.
