State Of Colorado Immunization Records 2026 Guide

What Is the Colorado Immunization Information System?

The Colorado Immunization Information System, or CIIS, is Colorado’s official immunization registry. CDPHE describes CIIS as a lifelong immunization record tracking system under the Colorado Immunization Registry Act of 2007. CDC also identifies Colorado’s IIS as CIIS and says it includes immunization records for vaccine recipients of all ages.

CIIS helps collect and consolidate vaccine information from providers, pharmacies, schools, child care users, public health agencies, and other authorized sources when doses are reported and matched. It is useful, but it is not guaranteed to show every vaccine ever received.

How to Get Colorado Immunization Records Step by Step

Use this order. It starts with the official public portal, then moves to the backup routes that solve most missing-record problems.

1. Open the CIIS Public Portal. Use the official Colorado public portal and choose whether the request is for yourself or a legal dependent.
2. Enter the person’s information exactly as the healthcare provider recorded it. The portal warns that an exact match is required. Try legal name, middle initial, hyphenated name, old surname, or the spelling used by the clinic if the first search fails.
3. Complete identity verification. The portal process includes entering information, receiving a verification code, and then viewing immunizations if the match succeeds.
4. Print or save the record. If the record appears, review the name, date of birth, vaccine names, and dose dates. Print it or use “Save as PDF” for a clean digital copy.
5. Use the CDPHE release form route if the portal does not work. CDPHE also provides a Request to Release Immunization Record Form route for yourself or your child.
6. Contact the provider or pharmacy that gave the missing vaccine. If a dose was given in Colorado but is missing from CIIS, the provider or pharmacy that administered it is usually the best correction route.
7. Check another state if the vaccine was not given in Colorado. CIIS may not automatically show doses from Wyoming, Utah, New Mexico, Kansas, Nebraska, Arizona, Texas, California, Illinois, or another state unless they were exchanged or later entered.

CIIS Public Portal Exact-Match Help

The CIIS Public Portal requires the details you enter to match the information documented at the healthcare provider. A failed search often means a matching problem, not a vaccine problem.

CDPHE Request to Release Immunization Record Form

If the CIIS Public Portal does not work, CDPHE provides a Request to Release Immunization Record Form route for individuals and parents or guardians of minors. CDPHE says incomplete forms, forms without proper ID, or forms without supporting documentation when applicable will not be accepted.

This backup route is helpful when identity verification fails, the portal cannot find a match, a parent needs a child’s record, a legal guardian needs supporting documentation, or a clean official copy is required by school, college, employer, travel office, or immigration-related paperwork.

How to Print or Save a Colorado Immunization Record

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

1. Open the matched record. Confirm the name and date of birth belong to the correct person.
2. Check vaccine names and dates. Look for required vaccines such as DTaP, Tdap, MMR, varicella, hepatitis B, polio, meningococcal, flu, COVID-19, or other program-specific vaccines.
3. Use browser print or save as PDF. On a computer, press Print and choose “Save as PDF.” On a phone, use the browser share or print menu.
4. Upload through trusted portals only. Use school, college, employer, healthcare program, or travel office upload systems when available.
5. Keep a backup copy. Save one PDF and one printed copy with other health documents.

Colorado School, Child Care, Camp and Tdap Record Requirements

Colorado school and child care vaccine proof can involve a CIIS record, provider record, school form, in-process plan, or exemption certificate. CDPHE’s school requirement pages explain documentation for school, child care, preschool, camp, and college/university settings.

For the current 2025–2026 school year, CDPHE says students are required to have a dose of Tdap before sixth-grade entry. Starting in the 2026–2027 school year, Colorado law will require students to have one dose of Tdap before the first day of seventh grade.

Colorado Medical and Nonmedical Exemption Records

Colorado exemption processes are separate from simply finding a vaccine record. For nonmedical exemptions, CDPHE says families can complete the Online Immunization Education Module or obtain a signature from an authorized healthcare provider who is willing to provide consultation and sign the Certificate of Nonmedical Exemption.

CDPHE says the exemption process and forms are for Colorado school-required vaccines only. Check with the school, child care, camp, or college to learn whether it wants a printed certificate, a submitted CIIS record, or another approved format.

myColorado, COVID-19 Vaccine Record and Colorado SMART Health Card

The myColorado app provides access to an official COVID-19 vaccination record from CIIS. This is useful for COVID-19 proof and can include the Colorado SMART Health Card option, but it does not replace the full CIIS Public Portal for all routine immunization records.

Pharmacy, Provider and Health System Vaccine Records in Colorado

Many Colorado adults receive vaccines at pharmacies or health systems instead of one family doctor. Flu, COVID-19, RSV, shingles, pneumonia, hepatitis, Tdap, and travel vaccines may appear in CIIS if reported and matched, but the pharmacy or provider portal is often the fastest backup.

Why Your Colorado Immunization Record May Be Missing

A missing CIIS result does not automatically mean the vaccine never happened. It may mean the vaccine was not reported, the search information does not exactly match, the dose was given out of state, the vaccine was entered under old information, or the record is stored with a pharmacy, school, employer, federal provider, or old clinic.

Colorado Local Help: Denver, Colorado Springs, Aurora, Fort Collins, Boulder, Pueblo and Grand Junction

Local help matters when the portal fails, when a child record is needed, when an old clinic closed, or when a school or child care office needs a specific record format. CDPHE provides a local public health agency lookup by county.

Out-of-State and Transfer Vaccine Records for Colorado Residents

If you moved to Colorado or received vaccines outside Colorado, CIIS may not automatically contain your full vaccine history. Contact the immunization registry in the state where the vaccine was given, then bring the official record to your Colorado provider, school, college, employer, or local public health agency if it needs review.

CDPHE notes that Colorado has interjurisdictional data exchange with some states, including Arizona, Kansas, Nevada, New Mexico, Oklahoma, Pennsylvania, and Wyoming. Even with exchange, do not assume every dose will appear. The cleanest record often comes from the state or provider where the vaccine was actually administered.

Titer Tests When Colorado Vaccine Records Are Lost

A titer is a blood test that may show immunity to some diseases. Titers can help when adult childhood records are lost, especially for healthcare jobs, nursing school, clinical training, college programs, or immigration paperwork. But the organization asking for proof decides whether titers are accepted.
