Need Colorado state immunization records for school, child care, college, a healthcare job, travel, immigration paperwork, camp, sports, COVID-19 proof, or your own family file? Colorado’s official registry is the Colorado Immunization Information System, called CIIS. This guide explains how to use the CIIS Public Portal, how to print an official record, when to use CDPHE’s release form, and what to do when a provider, pharmacy, school, out-of-state, or old record is missing.
To get Colorado state immunization records, start with the official CIIS Public Portal. Individuals and parents or guardians of minors can use the portal to request, view, and print an official immunization record when the information entered matches CIIS.
Official first step: CIIS Public Portal and CDPHE copy of recordsIf the portal does not find the record, do not assume the vaccine never happened. CIIS records may be incomplete because they include only immunizations reported and entered into CIIS. Use the CDPHE Request to Release Immunization Record Form, then check the original provider, pharmacy, school, local public health agency, employer, military record, or previous state registry.

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. Immunization records in CIIS are confidential personal medical information.
Official registry page: Colorado Immunization Information SystemCIIS can include vaccine information reported by health care providers, pharmacies, schools, child care users, and public health agencies. It is helpful, but it is not guaranteed to show every vaccine ever received. Older vaccines, out-of-state vaccines, military records, foreign records, and doses from non-reporting providers may be missing.
Public record guidance: Information about CIIS and immunization recordsUse the CIIS Public Portal first, then provider, pharmacy, CDPHE release form, or prior state registry if incomplete.
Open portalParents or legal guardians can request a record for a legal dependent when the portal can match the child’s details.
Parent record optionsColorado schools and licensed child cares may need a record, in-process plan, or exemption certificate.
School vaccine resourcesHow to Get Colorado State Immunization Records Online
Use this order. It starts with the official public portal, then moves to backup routes that solve most missing-record problems.
- Open the official CIIS Public Portal. Use copublicportal.state.co.us and choose whether the request is for yourself or a legal dependent.
- Enter information exactly as the health care provider documented it. The portal warns that an exact match is required. Try legal name, middle initial, hyphenated name, old surname, old phone, old email, or the spelling used by the clinic if the first search fails.
- Complete identity verification. The public portal process includes entering information, receiving a verification code, and then viewing immunizations if the match succeeds.
- Print or save the record. If the record appears, review name, date of birth, vaccine names, dose dates, and missing vaccines before using it.
- Use the CDPHE release form if the portal does not work. CDPHE provides a Request to Release Immunization Record Form route for individuals and parents or guardians of minors.
- Contact the provider or pharmacy that gave the missing vaccine. If a dose was given in Colorado but does not appear in CIIS, the provider or pharmacy is usually the best correction route.
- 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, Oklahoma, Texas, California, or another state.
CIIS Public Portal Exact-Match Help
The CIIS Public Portal requires the details you enter to match the information documented by the health care provider. A failed search often means a matching problem, not a vaccine problem.
Portal example: CIIS dependent request information screen| Portal detail | Why it matters | What to try |
|---|---|---|
| First and last name | The portal needs the name to match the provider’s record. | Try legal name, maiden name, hyphenated name, middle initial, or clinic spelling. |
| Date of birth | A single wrong digit can block the match. | Check month, day, and year carefully before submitting. |
| Phone or email | Verification and record matching may rely on old contact details. | Try the phone or email used when the vaccine was given. |
| Legal dependent | Parent or guardian requests must match the dependent record. | Use the child’s name exactly as the pediatrician, school, or clinic recorded it. |
| Duplicate profile | Records can split when providers use different demographics. | Ask the provider, pharmacy, or CIIS support whether duplicate records exist. |
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.
Official form route: Get a copy of your immunization records from CIISCDPHE says immunization records requested through the form are securely transmitted to the requester by fax or secure email. Use the latest CDPHE page before sending private information because forms, ID rules, and delivery instructions can change.
| Form situation | Why use it | Smart move |
|---|---|---|
| Portal cannot match | The record may exist but not match public-search details. | Submit complete information and proper ID through CDPHE instructions. |
| Child or legal dependent | Guardian documentation may be needed. | Include required supporting documents if CDPHE asks for them. |
| Official copy needed | Some organizations want a clean official record instead of a screenshot. | Ask the receiving office what exact format it accepts. |
| Secure delivery | CDPHE says records are sent by fax or secure email. | Use a secure email and double-check fax numbers if applicable. |
How to Print or Save a Colorado Immunization Record
When CIIS finds a 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.
Public portal help: How to use the CIIS Public Portal- Open the matched record. Confirm the name and date of birth belong to the correct person.
- Check vaccine names and dates. Look for required vaccines such as DTaP, Tdap, MMR, varicella, hepatitis B, polio, meningococcal, flu, COVID-19, or program-specific vaccines.
- 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.
- Upload through trusted portals only. Use school, college, employer, healthcare program, or travel office upload systems when available.
- Keep a backup copy. Save one PDF and one printed copy with other health documents.
Colorado School, Child Care, Camp and College Immunization Records
Colorado school and child care vaccine proof can involve a CIIS record, provider record, Colorado Certificate of Immunization, in-process plan, or exemption certificate. CDPHE’s school requirement pages explain documentation for school, child care, preschool, camp, and college or university settings.
Official school resources: CDPHE immunization requirements and school resources| Colorado situation | Likely proof needed | Best action |
|---|---|---|
| Child care or preschool | Vaccine record, in-process plan, or exemption certificate. | Ask the provider, child care office, or local public health agency what format is accepted. |
| K-12 school entry | CIIS printout, provider record, Colorado Certificate of Immunization, or exemption document. | Check the school packet, then use CIIS portal or provider record. |
| 7th grade or adolescent update | Updated vaccine dates, often including Tdap and other grade-level requirements. | Ask the school or provider which dose is missing before scheduling. |
| New transfer student | Previous state record reviewed for Colorado requirements. | Bring old records to a Colorado provider, school, or local public health agency. |
| College or healthcare program | Campus form, uploaded vaccine dates, provider signature, or titers. | Ask the student health portal or clinical coordinator before paying for lab work. |

Other state help: CDC IIS contacts for immunization records| Problem | Likely reason | Best next move |

Pharmacy, Provider, Hospital and Clinic Records in Colorado
Many adult Colorado vaccines are given at pharmacies, employer clinics, travel clinics, urgent care, hospitals, or local public health clinics. Flu, COVID-19, RSV, shingles, pneumonia, hepatitis, Tdap, and travel vaccines may be easiest to confirm through the original vaccine location.
Check the same phone, email, app account, and store used when the vaccine was given.
Ask the pharmacy location for a vaccine administration record or immunization history.
Check MyChart, Kaiser, UCHealth, CommonSpirit, Denver Health, or clinic patient portals.
Ask occupational health or HR where workplace vaccine records were stored or reported.
Check VA, TRICARE, base clinic, federal employee health, and civilian CIIS records separately.
Ask for vaccine name, exact date, provider details, and travel documentation if required.
Out-of-State Immunization Records for New Colorado Residents
If you moved to Colorado from another state, CIIS may not have every vaccine automatically. CDPHE notes that people can contact the IIS in the state or territory where the vaccines were received, and Colorado providers may have exchange with some states.
Official CDPHE help: Finding an immunization recordBring the out-of-state record to a Colorado provider, school, child care office, college, employer, or local public health agency for review. If the record is from another country, bring the original record, translation if needed, and any clinic paperwork.
National registry directory: CDC IIS contactsTiter Tests When Colorado Immunization Records Are Lost
A titer is a blood test that may show immunity to certain diseases. It can help when childhood records are lost, especially for healthcare jobs, college clinical programs, nursing school, military paperwork, or immigration medical exams. But the organization asking for proof decides whether titers are accepted.
| Need | Titers may help with | Ask first |
|---|---|---|
| Healthcare job | MMR, varicella, hepatitis B. | Ask occupational health which test and result format it accepts. |
| Nursing or clinical school | MMR, varicella, hepatitis B. | Ask whether positive IgG titers replace vaccine dates. |
| Immigration medical exam | Civil surgeon-reviewed proof. | Ask the civil surgeon before ordering labs or repeating vaccines. |
| School or child care | Limited situations only. | Follow CDPHE, school, provider, and local public health instructions. |
