How to Get Colorado Vaccination Records Online in 2026

What Is CIIS for Colorado Vaccination Records?

CIIS stands for Colorado Immunization Information System. CDPHE describes CIIS as Colorado’s lifelong immunization record tracking system under the Colorado Immunization Registry Act of 2007. It is a confidential registry used by authorized health care providers, pharmacies, schools, child care programs, local public health agencies, and other approved users.

For residents, the practical point is simple: CIIS is the main state registry source, but it can only show records that were reported, entered, and matched. If a vaccine was given in another state, entered under a different name, kept only on paper, or never reported, the portal may not display it.

What the CIIS Public Portal Can Do

The CIIS Public Portal lets you request a vaccination record for yourself or your legal dependent. The portal workflow asks you to enter personal information, verify your identity, and then view immunizations if the record can be matched.

The portal is strict about matching. The public portal page says information must be entered exactly how it is documented at the health care provider, and an exact match is required to obtain the immunization record. That means old names, phone numbers, spelling, hyphens, guardian details, and date of birth mistakes can stop a match.

How to Get Colorado Vaccination Records Online Step by Step

Use this order when you need a Colorado immunization record quickly. It keeps you on official sources and gives backup routes if the online portal does not find the record.

1. Open the official CIIS Public Portal. Start at the Colorado public portal, not a third-party website. Vaccine records contain private medical information.
2. Choose “Me” or “Dependent.” Use “Me” for your own record. Use “Dependent” only when you are the parent, guardian, or legally authorized person for a minor or dependent.
3. Enter the information exactly as the provider has it. Try the legal name, previous last name, hyphenated name, old phone, old email, or address that may have been used at the vaccine appointment.
4. Complete identity verification. Follow portal prompts. If verification fails, recheck the information instead of guessing repeatedly.
5. Review the immunization record. Confirm the record belongs to the correct person and includes the vaccine names and dose dates needed by the school, employer, college, travel clinic, or civil surgeon.
6. Print or save a clean copy. Keep one PDF and one paper copy. Name the file clearly, such as “Colorado-Vaccination-Record-2026.pdf.”
7. If the portal fails, use CDPHE’s backup routes. Try CDPHE’s copy-of-records page, the release form route, CIIS Help Desk, the original provider or pharmacy, or a local public health agency.

Information You Need Before Searching CIIS

Most failed searches come from a mismatch between what you enter and what the vaccine provider reported. Before you start, collect these details so you can search accurately or explain the issue to CIIS support.

How to Print, Download or Request a Colorado Vaccination Record

When the CIIS Public Portal finds the record, review it before using it. For school, child care, camp, college, employment, immigration, travel, or licensing, the receiving office usually needs exact vaccine names and dose dates, not just a statement that vaccines were completed.

If the portal does not work, CDPHE’s copy-of-records page provides a release-form route for requesting CIIS records. Make sure the form is complete and follow current ID or documentation instructions. If the vaccine was given by a pharmacy, clinic, or provider and not shown in CIIS, contact that source directly.

myColorado, COVID-19 Records and SMART Health Cards

Colorado offers myColorado myVaccine Record for COVID-19 vaccination proof when the record is available from CIIS. This can be helpful for a COVID vaccine record or Colorado SMART Health Card, but it does not replace every full vaccine record need.

If you need a complete routine immunization history for school, child care, camp, healthcare employment, college, travel, or immigration paperwork, start with the CIIS Public Portal and your provider record, not only a COVID-focused digital card.

Colorado School, Child Care and Camp Vaccination Records

Colorado schools, child care programs, Head Starts, and camps may require an immunization record, a Certificate of Immunization, an exemption certificate, or an in-process plan depending on the situation. CDPHE school guidance shows that a student immunization file may include records proving the child is up to date, exemption documentation, or a plan for catching up.

For the 2026-2027 school year, CDPHE school resources state that Colorado law will require students to receive a Tdap dose before the first day of seventh grade. Families should check the current school packet and CDPHE requirements before the deadline because grade-level rules can change.

Adult Colorado Vaccination Records

Adults often need Colorado vaccination records for healthcare jobs, nursing school, college, travel, immigration medical exams, public safety work, military paperwork, caregiver jobs, licensing, or personal medical history. CIIS can help when doses were reported, but older adult childhood vaccines may still require provider, school, military, or paper-record searches.

Why Your Colorado Vaccination Record May Be Missing or Incomplete

A missing Colorado record does not automatically mean the vaccine was never given. It may mean the record was not reported to CIIS, the information does not exactly match, the vaccine was given outside Colorado, the provider entered the record under another profile, or the vaccine exists in a pharmacy, military, school, or older paper file.

What to do next when CIIS does not find the record

1. Try the portal again with exact details. Use the name, birth date, and contact information used at the vaccine appointment.
2. Call the provider or pharmacy that gave the vaccine. The original source is usually best for missing dose corrections.
3. Use CDPHE’s copy-of-records route. Follow current release-form instructions if the portal does not work.
4. Contact the CIIS Help Desk. Use official CDPHE contact information for registry-related help.
5. Check other states. Use CDC’s IIS directory for vaccines given outside Colorado.
6. Ask about titers or revaccination only when needed. Do this after the school, employer, college, or civil surgeon confirms what it accepts.

Colorado Local Public Health Help: Denver, Colorado Springs, Aurora, Fort Collins, Boulder and Pueblo

If the CIIS Public Portal does not find your record, a provider closed, a school deadline is close, or you need help with a child’s record, a local public health agency can be a practical next step. Call before visiting because ID, appointment rules, and forms can vary by location.

CVS, Walgreens, Walmart, King Soopers, Safeway and Pharmacy Vaccine Records in Colorado

Many Colorado adults received COVID-19, flu, RSV, shingles, hepatitis, Tdap, pneumonia, or travel vaccines at a pharmacy. These doses may appear in CIIS if reported and matched, but the pharmacy account is often the fastest backup when the state portal is incomplete.

Out-of-State, Military, Foreign and Old Colorado Vaccine Records

You moved to Colorado from another state

Vaccines given outside Colorado may not automatically appear in CIIS. CDPHE says people can contact the IIS in the city, state, or territory where the person received their last vaccines. CDPHE also notes CIIS has interjurisdictional data exchange with some states, but you should still contact the state where the vaccine was actually given when proof is missing.

You were vaccinated by the military, VA, or federal care

Military, VA, TRICARE, federal occupational health, and base clinic vaccines may be stored in federal systems instead of CIIS. Check those systems directly and keep copies with your Colorado civilian vaccine file.

You were vaccinated outside the United States

Bring the original foreign vaccine record, translation if needed, and any clinic paperwork to your Colorado provider, school, college health office, employer, or civil surgeon. The receiving office may need vaccine names, exact dates, spacing review, titers, or repeat doses.

Your old doctor retired or the clinic closed

Search for the clinic’s successor practice, health system, medical records custodian, old patient portal, former school, college health center, employer health office, pharmacy records, and local public health agency. For older adult records, this may work better than expecting every childhood dose to appear online.

Titer Tests When Colorado Vaccination Records Are Missing

A titer is a blood test that checks for antibodies showing immunity. It may help when adult childhood records are missing, especially for healthcare jobs, nursing school, medical programs, college requirements, or immigration medical exams. The organization asking for proof decides whether titers are accepted.
