Immunization Records Colorado: CIIS Portal, School & CDPHE Help

Need immunization records Colorado online for school, child care, college, work, healthcare training, travel, immigration, COVID-19 proof, or your own family file? Colorado uses CIIS, the Colorado Immunization Information System, for many official vaccine records. This guide explains the fastest online route, the CDPHE release form backup, school and exemption records, pharmacy records, myColorado COVID-19 records, and what to do when the record is missing or incomplete.

Quick answer

To get immunization records in Colorado, start with the official CIIS Public Portal. Individuals and parents or guardians of minors can use the portal to view and print an official record when a matching CIIS record is found. If the portal does not work, use CDPHE’s Request to Release Immunization Record Form or contact the provider, pharmacy, school, or local public health agency that may hold the record.

Official online route: CIIS Public Portal

A “no record found” result does not always mean the person was never vaccinated. It may mean the dose was not reported to CIIS, the name or date of birth does not match exactly, the record is under an old phone number, or the vaccine was given outside Colorado.

What Is CIIS for Colorado Immunization Records?

CIIS stands for Colorado Immunization Information System. It is Colorado’s statewide immunization registry operated by the Colorado Department of Public Health and Environment. CIIS is used to help track immunization history, but it only works well when vaccine doses were reported correctly and the record details match.

Official background: Colorado Immunization Information System

CIIS records are confidential medical information, not a public people-search database. The right route depends on who is requesting the record, whether the person is an adult or minor, where the vaccine was given, and whether the record can be matched in the system.

Official public access route: CIIS Public Portal
Adults

Start with the CIIS Public Portal, then use the CDPHE form if a match is not found.

CDPHE request route
Parents and guardians

Use the portal or release form for a legal dependent when you are allowed to request the record.

Dependent record request
Students

Schools may need a CIIS record, provider record, in-process plan, or exemption certificate.

School requirements
Senior-friendly reminder If computers are difficult, call the provider, pharmacy, or local public health agency first and ask for “immunization record help.” Keep your legal name, date of birth, old last name, old phone number, and the clinic or pharmacy name nearby.

How To Get Immunization Records Colorado Online Step by Step

Use this order. It avoids fake lookup sites and gives you a clean fallback when the portal cannot find the record.

  1. Open the official CIIS Public Portal. Start with the state portal for Colorado immunization records. Choose whether the request is for you or for a legal dependent.
  2. Enter the same details your provider used. A record match can fail if the name, date of birth, phone number, email, previous last name, or hyphenated spelling does not match the original record.
  3. Complete identity verification. Follow the portal prompts. Keep access to your phone or email open while completing the request.
  4. Review and save the record. If the record appears, check vaccine names and dates before using it for school, work, college, travel, or immigration paperwork.
  5. Use CDPHE’s release form if the portal fails. The release form is the official backup route for individuals and parents or guardians of minors requesting CIIS records.
  6. Call the provider or pharmacy for missing vaccines. If a vaccine is missing, the office or pharmacy that gave the dose may have a separate record or may need to correct reporting.
  7. Check another state if the vaccine was not given in Colorado. Contact the IIS in the state or territory where the vaccine was administered.
Deadline warning Do not wait until the first day of school, job onboarding, or a travel appointment. If your record is split between Colorado, a pharmacy, an old doctor, and another state, it may take several tries to rebuild.

CIIS Public Portal: Fastest Online Starting Point

The CIIS Public Portal is the best first online step for immunization records Colorado searches. The portal can help you view and print an official record when the identity information matches a CIIS record. Use only the official portal before trying any third-party vaccine lookup website.

Official portal: CIIS Public Portal
Portal step What it means Best action
Choose requester Select yourself or a legal dependent. Use the dependent option only if you are legally allowed to request that record.
Enter identity details The portal needs a matching record. Use legal name, previous name, exact date of birth, and provider spelling.
Verify access The system may require confirmation. Keep phone or email ready while completing the process.
View or print A matched record may be available. Save a PDF and print one copy before closing the portal.
No match The record may still exist somewhere else. Use CDPHE form, provider, pharmacy, school, or another state registry route.
Exact-match tip Try only real name variations that may have been used by a provider, such as maiden name, hyphenated name, or old last name. Never guess or invent vaccine dates.

When To Use the CDPHE Request to Release Immunization Record Form

If the CIIS Public Portal does not work, CDPHE provides the Request to Release Immunization Record Form route. This is useful when the online lookup cannot match the record, when a parent or guardian needs manual processing, or when a secure fax or secure email copy is needed.

Official form page: Get a copy of your immunization records from CIIS

Before submitting, check every required field. CDPHE says incomplete forms, missing proper ID, or missing supporting documentation when applicable will not be accepted. That means one missing attachment can delay the whole request.

What to prepare Why it matters Before you send
Completed release form CDPHE needs clear authorization and identity details. Review every required line before submitting.
Proper ID Protects confidential medical information. Make sure the name and birth date match the request.
Guardian proof May be needed when requesting for a minor or dependent. Attach supporting documentation if the form requires it.
Fax or secure email access Records may be sent securely by fax or secure email. Use contact details you can access reliably.
Best use for the form Use the release form after the portal fails, when you need manual help, or when a school, employer, or program needs a secure official copy.

Colorado School, Child Care, Camp and College Immunization Records

Colorado law requires students attending Colorado K-12 schools, licensed child cares, camps, and colleges or universities to be vaccinated against certain diseases unless a valid exemption is on file. This is why schools may ask for immunization records, exemption certificates, or an in-process plan.

Official school page: Colorado immunization requirements for school entry

For parents, the right move is to ask the school what exact record is missing, then use CIIS, the child’s provider, pharmacy, previous school, or local public health agency to fill the gap. A pharmacy receipt may not be enough if the school needs a specific student immunization record.

School situation Likely proof needed Best action
Child care or preschool Vaccine record or exemption documentation. Ask the provider, child care office, or local public health agency what format they accept.
K-12 school entry Student immunization record, in-process plan, or exemption certificate. Check school packet, then use CIIS portal or provider record.
New Colorado transfer Previous state record reviewed for Colorado requirements. Bring old records to a Colorado provider, school, or local public health agency.
College or university Campus vaccine upload, dates, forms, or titers. Check the student health portal before paying for labs.
Healthcare training MMR, varicella, hepatitis B, Tdap, flu, COVID-19, TB, or titers. Ask the clinical program or occupational health office for exact proof.
Parent mistake to avoid Do not upload a random screenshot unless the school says it is acceptable. Ask for the exact document name, vaccine names, and deadline.

Details You May Need Before Requesting a Colorado Immunization Record

Small details can decide whether the portal finds your record. Before you start, gather the information that matches the provider, pharmacy, or school record as closely as possible.

Detail Why it helps Smart tip
Full legal name Record matching depends on identity details. Try previous name, maiden name, or hyphenated name if that was used by the provider.
Date of birth Separates similar names. Double-check month/day/year before submitting.
Phone or email May support identity verification or matching. Try old legitimate contact details if the vaccine was years ago.
Parent or guardian details Important for minor records. Use the guardian information used by the provider or school.
Provider or pharmacy name Helps recover missing vaccines. List clinics, hospitals, pharmacies, school clinics, and public health offices.
Proper ID Required for release form requests. Read CDPHE’s current instructions before sending documents.
Two-minute prep Write down the names of every place that may have given vaccines: pediatrician, family doctor, CVS, Walgreens, Walmart, Safeway, King Soopers, college clinic, military clinic, travel clinic, and previous state health department.

What If Colorado Immunization Records Are Missing?

A missing Colorado immunization record does not automatically mean the vaccine was never given. The dose may not have been reported to CIIS, may have been entered under different details, may be in another state registry, or may only exist in an old provider, pharmacy, school, military, or paper record.

Other state help: CDC IIS contacts for immunization records
Problem What it means What to try next
Exact-match failure The portal cannot match the details entered. Try legal name, previous name, hyphenated name, and exact birth date.
Old childhood records Older records may be paper-only or incomplete in CIIS. Check school records, pediatrician files, old paper cards, and family folders.
Out-of-state vaccine The dose may be in another state or territory registry. Contact the state where the shot was given.
Pharmacy vaccine Record may be under a pharmacy profile, old phone number, or old email. Call the pharmacy location and ask for vaccine administration history.
Duplicate profile Vaccines may be split across two records. Ask provider or CIIS support whether duplicates could exist.
Federal or military care VA, TRICARE, base clinic, or federal records may be separate. Check VA, TRICARE, military clinic, or service medical records.
  1. Recheck the portal details. Use the exact name, date of birth, and contact information that likely match the record.
  2. Contact the original provider. Ask the doctor, clinic, pharmacy, hospital, or local public health agency for vaccine history.
  3. Check school or college files. Former schools may still have vaccine paperwork submitted during enrollment.
  4. Check previous states. Use the state or territory where the vaccine was actually given.
  5. Ask a clinician about next steps. If no record exists, a provider may discuss titer testing or catch-up vaccination.
Do not guess vaccine dates Incorrect vaccine dates can cause school, employment, immigration, travel, and healthcare paperwork problems. Use verified records or ask a licensed provider what to do.

Colorado COVID-19 Immunization Records and myColorado

For COVID-19 vaccine proof, Colorado residents may use the myColorado COVID-19 Vaccination Record feature when available. It provides secure access to the official COVID-19 vaccination record within CIIS, and can show a Colorado SMART Health Card or a digital version of a CDC COVID-19 vaccination card.

Official app page: myVaccine Record in myColorado

myColorado is useful for COVID-19 proof, but it does not replace every record need. Schools, child care programs, colleges, healthcare employers, immigration medical offices, and travel clinics may require a broader immunization record or a specific document format.

Record route Best for Limit
CIIS Public Portal General Colorado immunization record access. Needs a matching CIIS record.
CDPHE release form Manual record request and secure transmission. Incomplete forms or missing ID may be rejected.
myColorado COVID-19 vaccine proof. Not a full replacement for every non-COVID record need.
Provider or pharmacy portal Vaccines given at that office or pharmacy. May show only that organization’s records.
COVID record tip If myColorado does not show the COVID-19 record, contact the provider or pharmacy that gave the shot and ask whether the information was reported correctly to CIIS.

Colorado Pharmacy Immunization Records: CVS, Walgreens, Walmart, Safeway and King Soopers

Many Colorado adults received COVID-19, flu, RSV, shingles, pneumonia, hepatitis, Tdap, or travel vaccines at a pharmacy. These doses may appear in CIIS if reported and matched, but the pharmacy profile is often the fastest place to check first.

Old-record help: Tips for locating old immunization records
CVS and MinuteClinic

Check the same CVS account, phone number, or email used for the vaccine appointment.

Walgreens

Use the Walgreens pharmacy account or call the store where the vaccine was administered.

Walmart pharmacy

Ask the exact Walmart pharmacy location for a vaccine administration record.

Safeway pharmacy

Check the pharmacy profile or ask the local Safeway pharmacy for vaccine dates.

King Soopers pharmacy

Call the pharmacy if adult vaccines do not show in your online profile.

Travel clinic

Ask for vaccine names, dates, and official documentation before a travel deadline.

Colorado Immunization Exemptions for School-Required Vaccines

Colorado has official medical and nonmedical exemption processes for school-required vaccines. CDPHE says students with an exemption on file may be kept out of school or child care during a disease outbreak, and families are responsible for providing a copy of the exemption certificate to each school or child care attended.

Official exemption page: Exemptions to school-required vaccines
Exemption item What it means Where to confirm
Medical exemption Used when a medical condition affects vaccination. CDPHE, healthcare provider, and school instructions.
Nonmedical exemption Colorado process for religious or personal belief exemption from school-required vaccines. CDPHE’s official exemption page and the school office.
CIIS opt-out A separate process for excluding information from CIIS. CDPHE CIIS opt-out instructions.
Workplace vaccines Employer requirements are separate from school-required vaccine exemptions. Your employer or occupational health office.
Important distinction Opting out of CIIS is not the same thing as completing a school vaccine exemption. Use the correct CDPHE process for your situation.

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

If the 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.

Official contacts: Colorado immunization contacts
If you live near Common need Best next step
Denver Denver immunization records, school proof, adult records. Try CIIS, provider, pharmacy, then local public health support.
Colorado Springs El Paso County vaccine record help. Use CIIS and provider records before calling local public health.
Aurora Student, pharmacy, or health system vaccine records. Check the healthcare system or pharmacy that gave the vaccine.

Call-before-you-go tip Ask what ID, proof of guardianship, appointment, form, or portal printout you should bring before visiting a local office.

Out-of-State Immunization Records for New Colorado Residents

If you moved to Colorado from another state, CIIS may not have every vaccine automatically. Contact the immunization registry in the state or territory where the vaccine was given, then bring that record to a Colorado provider, school, child care office, college, employer, or local public health agency for review.

Find another state registry: CDC IIS immunization record contacts

If the record is from another country, bring the original record, translation if needed, and any clinic paperwork. The receiving organization may need vaccine names, exact dates, and spacing review before accepting it.

Do not hand over your only copy Scan or photograph old paper vaccine cards before giving a copy to a school, employer, clinic, or public health office.

Titer 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.

Situation Titers may help with Ask first
Healthcare job MMR, varicella, hepatitis B. Ask occupational health what lab format they accept.
Nursing or medical 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 paying for labs.
K-12 school Limited cases only. Follow school and CDPHE instructions before ordering tests.
Money-saving rule Do not order titers until the school, employer, college, licensing board, or civil surgeon confirms exactly what they accept.

Source Check and Trust Note

This Colorado immunization record guide was built from official CDPHE, CIIS, myColorado, CDC, and public immunization-record guidance. Record access rules, portal matching, school deadlines, exemption processes, provider participation, pharmacy reporting, and local public health procedures can change. Always confirm final requirements with CIIS, CDPHE, myColorado, CDC, your provider, pharmacy, local public health agency, school, employer, college, licensing board, or civil surgeon.
