How to Get Colorado Immunization Records Online in 2026

Quick Facts About Colorado Immunization Records

Colorado immunization records may be available through CIIS, a health care provider, pharmacy, school, child care program, college, local public health agency, or the myColorado app for COVID-19 records. The best starting point depends on what record you need and whether CIIS has a matching record.

What Colorado Immunization Records Mean

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

A record may not be stored in only one place. Your doctor may have childhood vaccines, a pharmacy may have adult vaccines, a school may have a copy submitted earlier, and CIIS may include vaccines that were reported to the registry.

Common reasons people need Colorado immunization records

• School or child care enrollment in Colorado.
• College, health care, nursing, or training program requirements.
• Employment or occupational health onboarding.
• Travel clinic or immigration medical documentation.
• Replacing lost vaccine cards or older paper records.
• Checking whether a vaccine history in CIIS is complete.

What Is CIIS?

CIIS stands for Colorado Immunization Information System. It is Colorado’s lifelong immunization record tracking system operated by the Colorado Department of Public Health and Environment. CDPHE explains that immunization records are confidential personal medical information.

CIIS can help people, providers, schools, child care programs, and public health users review immunization information. It does not always contain every vaccine dose. It only includes what has been reported to and entered into CIIS.

Why CIIS may not show every vaccine

• The vaccine may have been given before electronic reporting was common.
• The provider, pharmacy, school, or federal clinic may not have reported it.
• The record may use a different name, date of birth, phone number, or email.
• The vaccine may have been given in another state or country.
• The person may have opted out of CIIS or had incomplete registry details.

How to Get Colorado Immunization Records Online

The official online route for most people is the CIIS Public Portal. It lets individuals and parents or guardians of minors request, view, and print an official immunization record when the information entered matches the record in CIIS.

1. Open the official CIIS Public Portal Go to copublicportal.state.co.us. Use only the official Colorado portal for online record lookup.
2. Choose who the request is for Select whether you are requesting a record for yourself or for a legal dependent. Parents and guardians may request records for minors when eligible.
3. Enter identity details exactly Use the name, date of birth, and contact details that match the health care provider’s record. Exact details matter because the portal must match your information.
4. Review and print the record if found If the portal finds a match, review the record carefully. Print or save a copy for school, work, travel, or personal files.
5. Check for missing vaccines Compare the record with provider, pharmacy, school, or personal vaccine cards. CIIS records may not be complete.
6. Use the CDPHE form if the portal fails If no record appears, use the CDPHE copy-of-records page and follow the Request to Release Immunization Record Form instructions.
7. Contact the provider if details are wrong If a vaccine is missing or incorrect, contact the provider or pharmacy that gave the vaccine. They may need to correct or submit information.

CIIS Public Portal: What to Expect

The CIIS Public Portal is the main online lookup tool for Colorado immunization records. It can be used by individuals and by parents or guardians requesting records for minors. If the system finds a matching record, you can view and print the official record.

The portal may not return a result if the information does not match. For example, a provider may have reported a different phone number, name spelling, email, or birth date. If this happens, do not assume the record is gone. Try the official request form or contact the provider.

When to Use the Record Request Form

Use the CDPHE Request to Release Immunization Record Form if you cannot access records through the portal, if a legal dependent’s record needs extra documentation, or if the portal does not find a match. CDPHE says incomplete forms, forms without proper ID, or forms without supporting documents may not be accepted.

The request form route is also useful when you need secure transmission by fax or secure email. Use the current official CDPHE copy-of-records page before submitting, because form links and instructions can change.

Information you may need for colorado immunization records

• Full legal name and any previous names.
• Date of birth.
• Parent or guardian information for a minor.
• Phone number or email used with the provider.
• Provider, pharmacy, school, or local public health agency details.
• Proper ID if required by the request form.
• Supporting documents if requesting for another person.

School, Child Care, and College Records

Colorado schools and licensed child care facilities may require immunization documentation before attendance. CDPHE school guidance says families may need an immunization record, an in-process plan, or a medical or nonmedical exemption certificate, depending on the student’s situation.

Schools, child cares, and Head Starts can use CIIS to look up, review, and print immunization records when they have approved access. They must complete training, create a user account, and follow confidentiality and security rules.

Adult Colorado Immunization Records

Adults may need colorado immunization records for college, health care work, military paperwork, travel, immigration medical exams, or personal history. Adult records can be harder to recover if vaccines were given years ago, outside Colorado, or before electronic reporting became common.

Start with the provider or pharmacy that gave the vaccine. For recent vaccines such as flu, COVID-19, shingles, RSV, Tdap, pneumonia, or travel vaccines, your pharmacy account or health system portal may be helpful.

Adult record recovery checklist

• Use the CIIS Public Portal first.
• Check your primary care provider or health system portal.
• Ask pharmacies where adult vaccines were given.
• Contact colleges, employers, military offices, or travel clinics.
• Check previous state immunization registries if you moved.
• Ask a clinician about titer testing or catch-up vaccination if records cannot be found.

COVID-19 Records and the myColorado App

The myColorado app offers access to an official COVID-19 vaccination record from CIIS. This is different from a full immunization history. The app can show a Colorado SMART Health Card and a digital COVID-19 vaccination card when a matching COVID-19 record is available.

myColorado states that the COVID-19 vaccination record feature is for your own personal record. It does not provide access to children’s records, and it does not show other immunizations besides COVID-19 vaccination information.

What If Your Record Is Missing?

A missing Colorado immunization record does not always mean the vaccine was never given. It may mean the provider did not report the dose, the details do not match, the vaccine was given outside Colorado, or the record is stored only in an older provider file.

1. Check your portal details Make sure your name, date of birth, email, and phone number match the provider’s record.
2. Contact the vaccine provider Ask the clinic, pharmacy, hospital, or local public health agency for a vaccine administration record.
3. Ask the provider to review CIIS reporting If the provider reported the wrong details, they may need to correct or submit the record.
4. Use the CDPHE record request form Submit the official request form if the Public Portal does not return your record.
5. Search older files Check school, college, employer, military, travel clinic, or previous state records.
6. Ask a clinician about next steps If no record can be found, ask whether titer testing, repeating a vaccine, or a catch-up schedule is appropriate.

Mistakes to Avoid When Requesting Colorado Immunization Records

Most delays happen when people use unofficial websites, enter details that do not match CIIS, assume myColorado shows every vaccine, or send private information through unsafe channels. A careful request can save time and protect your health information.

Official Help and Verification

Use official Colorado resources before relying on third-party information. Portal access, forms, contact details, school rules, and accepted documents can change. Always verify through CDPHE, CIIS, your provider, your school, or your local public health agency before taking action.

Privacy and Safety Notes

Immunization records include private health information. Do not upload identification, child details, medical records, or vaccine cards to random websites. Use official CDPHE, CIIS, provider, pharmacy, school, college, employer, or local public health routes.

If an employer, school, or program asks for your record, ask which format they accept. Some may accept a CIIS printout, while others may request a provider record or a specific school form.
