Colorado State Immunization Records 2026 Guide

Quick Facts About Colorado Immunization Records

Colorado immunization records may be available through CIIS, a doctor, clinic, pharmacy, school, child care center, local public health agency, college, employer, or older paper file. The CIIS Public Portal is the best first online route because it is the official state record access option for individuals and parents or guardians of minors.

What Colorado State Immunization Records Means

Colorado state immunization records are vaccine history documents that show which vaccines a person received and when. These records may be needed for Colorado school entry, child care, college, healthcare programs, employment, travel, military paperwork, immigration medical exams, or personal medical history.

The record may not come from one single place. CIIS is the official statewide immunization information system, but a provider, pharmacy, school, college, local public health agency, employer, military office, or older paper file may also hold important vaccine information.

Common reasons people request records

• Colorado school, preschool, child care, Head Start, or daycare enrollment.
• College, university, nursing, healthcare, or clinical program requirements.
• Employment, occupational health, public safety, or long-term care paperwork.
• Travel clinic, immigration, military, or personal medical record needs.
• Replacing a lost shot card, school record, or older paper vaccine history.

What Is CIIS?

CIIS stands for Colorado Immunization Information System. 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.

CIIS can include vaccine information reported and entered by health care providers, pharmacies, and some schools. CDPHE also explains that CIIS records may not be complete. If a vaccine was never reported, was entered under different details, or was given before full reporting, it may not appear.

How CIIS helps Colorado residents

• Stores reported immunization records in one state system.
• Lets individuals and parents or guardians view and print official records.
• Helps providers check vaccine history when access is allowed.
• Helps schools and child care programs review immunization records when approved.
• Supports safer record keeping when information is complete and accurate.

How to Request Colorado Immunization Records Online

The official online route is the CIIS Public Portal. CDPHE says individuals and parents or guardians of minors can use the portal to view and print an official record of immunizations. Use official CDPHE or state.co.us links, not random third-party lookup pages.

Use these steps when you need a record for school, work, college, child care, travel, or personal files.

1. Open the official CIIS Public Portal Go to the official CIIS Public Portal at copublicportal.state.co.us. Use the CDPHE record page if you want to confirm the link first.
2. Choose who the request is for Select whether you are requesting your own immunization record or a record for a legal dependent or minor.
3. Enter identity details carefully Use the same legal name, date of birth, phone number, email, or other details that may be documented with the health care provider.
4. Complete portal verification Follow the identity or verification steps shown by the portal. If the record does not match, review spelling, phone, email, and old address details.
5. View and print the record If the portal finds the record, save a digital copy and print a copy for school, work, travel, college, or personal files.
6. Use the CDPHE release form if needed If the portal does not work, use CDPHE’s Request to Release Immunization Record Form and include required ID or supporting documents.
7. Verify before relying on the record Ask the receiving school, employer, college, travel clinic, or program whether it accepts the CIIS portal record or needs another document.

When to Use the CDPHE Request Form

Use the CDPHE Request to Release Immunization Record Form when the portal does not find the record, when you need a secure release route, or when supporting documentation is required. CDPHE says incomplete forms, forms without proper ID, or forms without required supporting documentation will not be accepted.

CDPHE says immunization records requested through the form are securely transmitted to the requester by fax or secure email. Because form instructions can change, open the latest request page before sending private information.

Colorado School and Child Care Records

Colorado school and child care immunization documentation may have specific rules. CDPHE says Colorado law requires students attending Colorado schools and licensed child care facilities to be vaccinated against certain diseases unless a medical or nonmedical exemption certificate is on file.

For school use, ask the school what document it accepts. A CIIS record may help, but a Colorado Certificate of Immunization, provider record, school-approved form, or exemption document may be required depending on the situation.

Best steps for school records

1. Ask the school or child care office first Confirm whether the office needs a CIIS printout, Colorado Certificate of Immunization, provider record, or exemption certificate.
2. Use the CIIS Public Portal Try to view and print the child’s official immunization record through the public portal.
3. Contact the child’s provider Ask the pediatrician, family doctor, clinic, pharmacy, or local public health agency for a copy.
4. Check older school files If the child attended another Colorado school or daycare, ask whether a copy is still on file.
5. Start before enrollment season Schools, providers, and local public health agencies can become busy before the school year starts.

Adult Colorado Immunization Records

Adults may need Colorado immunization records for college, healthcare work, clinical programs, teaching, public safety jobs, travel, immigration medical exams, long-term care work, or personal medical files. Adult records may be incomplete if vaccines were given many years ago or outside Colorado.

Start with the CIIS Public Portal, then check the provider or pharmacy that gave the vaccine. For adult COVID-19 vaccination records, CDPHE notes that a digital copy may be available through the CIIS Public Portal and the myColorado mobile app.

Adult record recovery checklist

• Use the official CIIS Public Portal first.
• Ask your current doctor or health system for an immunization history printout.
• Check pharmacy accounts for flu, COVID-19, shingles, RSV, Tdap, travel, or pneumococcal vaccines.
• Contact former colleges, employers, healthcare programs, or military records offices.
• Use the CDPHE request form if the portal cannot find the record.
• Ask a clinician about titer testing or catch-up vaccination if proof cannot be found.

What If Your Record Is Missing?

A missing Colorado immunization record does not always mean the vaccine was never given. CDPHE explains that CIIS records may not be complete and include what has been reported to and entered into CIIS. Missing records may be stored with a provider, pharmacy, school, military office, or previous state registry.

Common reasons a record is not found

• The vaccine was not reported or entered into CIIS.
• The record has a different name, date of birth, phone number, or email.
• The vaccine was given outside Colorado.
• The dose is stored in a pharmacy, school, employer, military, or paper file.
• The vaccine was given before the record was added to a current system.
• The person or guardian opted out of CIIS in the past.

What to do next

1. Check identity details Try legal names, previous names, maiden names, hyphenated names, old phone numbers, emails, and previous addresses.
2. Contact the original provider Ask for a vaccine administration record, chart copy, patient portal record, or immunization printout.
3. Use the CDPHE request form Complete the Request to Release Immunization Record Form if portal access is not enough.
4. Search school and employer files Schools, colleges, employers, and military offices may have records submitted earlier.
5. Check previous state registries If vaccines were given outside Colorado, contact the previous state’s immunization registry or the provider.
6. Ask about clinical options If proof cannot be found, ask a licensed health care provider about titers, repeat doses, or catch-up vaccination.

Mistakes to Avoid

Many delays happen because people use unofficial lookup sites, enter details differently from the provider record, forget ID requirements, or assume CIIS has every vaccine ever received. A careful request protects privacy and improves your chance of getting the right document.

Privacy and Accuracy Notes

Immunization records contain private health information. CDPHE describes CIIS records as confidential personal medical information. Do not send your date of birth, child details, medical records, identification, or signed forms to random websites.

Before sending a record, ask the receiving office what format it accepts. A school, employer, college, travel clinic, or health care program may require a specific record type. Keep a digital and printed copy of every record you receive.

Official Help and Verification

Use official Colorado sources before making decisions. Portal instructions, form requirements, phone numbers, email routes, school rules, exemption rules, and record availability can change. Always check current CDPHE and CIIS pages before submitting private information.
