Need Colorado vaccine records for school, child care, college, healthcare work, travel, immigration paperwork, a lost COVID card, or your own family file? Colorado’s main immunization registry is CIIS, the Colorado Immunization Information System. This guide explains the official CIIS Public Portal, CDPHE record options, school proof, missing-dose fixes, pharmacy records, myColorado COVID records, and when to call a local public health agency.
To get vaccine records in Colorado, start with the official CIIS Public Portal. Individuals and parents or legal guardians of minors can request, view, and print available immunization records when the information entered matches the record in CIIS.

What Is CIIS for Colorado Vaccine Records?
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. It is used to help consolidate vaccine information reported by participating providers, public health agencies, pharmacies, and other authorized sources.
Official CIIS overview: Colorado Immunization Information SystemThe CIIS Public Portal is the safest first stop for Colorado residents because it lets an individual request a record for themselves or for a legal dependent. The portal asks for personal information and identity verification before showing available records.
Portal route: CIIS Public PortalUse CIIS Public Portal first, then provider, pharmacy, CDPHE, or local public health if nothing appears.

Colorado school requirementsHow to Get Vaccine Records Colorado in 2026
Use this order when you need a Colorado vaccine record quickly and safely. It starts with the official state portal, then moves to backup routes when the portal does not find a match.
- Open the CIIS Public Portal. Choose whether the request is for you or for your legal dependent. Enter the details exactly as they may appear in the provider’s record.
- Verify your identity if prompted. The portal may send a verification code or ask for matching information before it lets you view an available immunization record.
- View, download, print, or save the available record. If a record appears, save a PDF and print a readable paper copy for school, employment, travel, health care, or personal records.
- If no match appears, use CDPHE’s copy-of-records guidance. CDPHE provides instructions for people who need a copy of immunization records from CIIS.
- Contact the provider, pharmacy, or clinic that gave the vaccine. The original vaccine provider is often the best source for missing doses, wrong dates, or recently administered shots.
- Ask a local public health agency for help. Local public health can be useful when a school needs proof, the provider closed, or the CIIS record is incomplete.
- Check another state if the vaccine was not given in Colorado. CIIS may not contain all vaccines from Texas, California, Florida, Arizona, Kansas, Nebraska, Wyoming, New Mexico, Utah, another state, or another country.
Colorado Immunization Records Online: CIIS Public Portal Explained
The phrase “Colorado immunization records online” usually means the CIIS Public Portal. The portal is designed for individuals and parents or guardians of minors to request and print an available official immunization record. It is not a general account where unrelated people can search someone else’s vaccine history.
Official access: Open CIIS Public Portal| Portal step | What it means | Practical tip |
|---|---|---|
| Choose requester | Select whether the record is for you or for a legal dependent. | Parents should use the child’s exact legal information, not a nickname. |
| Enter details | CIIS tries to match the record using the information entered. | Use old phone/email if the vaccine was given years ago. |
| Verify identity | The portal may require a verification code or matching step. | Do not use someone else’s email or phone if you cannot receive the code. |
| View record | If a match is found, you may be able to view and print the record. | Save the PDF immediately and keep a printed backup. |
| No match | The record may be incomplete, mismatched, or outside CIIS. | Use CDPHE, provider, pharmacy, or local public health backup routes. |
Colorado Vaccine Records for School, Child Care, Camp and College
Colorado schools, child care programs, preschools, Head Start programs, camps, colleges, and healthcare training programs may ask for immunization documentation before attendance or placement. The correct proof can depend on the age, program, and whether the student is fully vaccinated, in process, medically exempt, or using a nonmedical exemption route.
Official school page: Colorado immunization requirements for school entryColorado’s official certificate and school documentation rules are not the same as a random vaccine list or screenshot. CDPHE’s camp guidance states that immunizations on Colorado’s Official Certificate of Immunization can be documented by healthcare providers, public health agencies, or a school health official.
Camp documentation rule: Colorado immunization requirements to attend camp| Situation | Likely proof needed | Best next step |
|---|---|---|
| Child care or preschool | Colorado immunization certificate, official record, or exemption paperwork. | Ask the child’s provider or local public health agency to review the record. |
| K-12 school | Official school-required immunization documentation or valid exemption. | Use CIIS, provider record, or school health office instructions. |
| Camp | Official Certificate of Immunization or accepted documentation. | Ask the camp which form and signature route it accepts. |
| College or university | Campus-specific proof, MMR record, TB form, or titers. | Check the college health portal before paying for labs. |
| Healthcare training | Vaccine dates, titers, TB screening, flu, COVID-19, or program form. | Ask the program for exact accepted proof. |

CVS, Walgreens, Walmart, Costco and Pharmacy Vaccine Records in Colorado
Many Colorado adults received flu, COVID-19, RSV, shingles, pneumonia, hepatitis, Tdap, or travel vaccines at a pharmacy. Those doses may appear in CIIS if reported and matched correctly, but the pharmacy account is often the fastest place to look first.
Use the same pharmacy chain, phone number, email, and date of birth used at the appointment. If you changed phones or used an old email, call the pharmacy location and ask for a vaccine administration record or immunization history.
General record-finding help: Tips for locating old immunization recordsCheck CVS or MinuteClinic records if your shot was given there.
Use the Walgreens pharmacy profile tied to the vaccine appointment.
Call the Walmart pharmacy where the shot was administered if online access fails.
Ask the Costco pharmacy location for a printable vaccine history.
Contact the pharmacy that gave the vaccine and ask whether the dose was reported.
Ask for vaccine names, dates, provider signature, and lot details if available.
Why Your Colorado Vaccine Record May Be Missing
A missing CIIS result usually means the portal could not match your information or the vaccine history is incomplete. It does not automatically mean the vaccine never happened. Records can be split across providers, pharmacies, states, schools, health systems, or older paper files.
CDPHE record page: Get a copy of your immunization records from CIIS| Problem | What it means | What to try next |
|---|---|---|
| Name mismatch | Record may use maiden name, old name, hyphenated name, nickname, or different spelling. | Try provider spelling and old legal names. |
| Wrong date of birth | A small data error can block the match. | Ask the provider or pharmacy to verify the demographic details. |
| Duplicate profiles | Some doses may sit in one record and other doses in another. | Ask the original provider or public health agency about duplicate records. |
| Out-of-state vaccine | Dose may be in another state’s immunization registry. | Use CDC’s IIS directory to contact that state. |
| Closed provider | Records may be with a successor clinic, hospital system, or custodian. | Search the clinic name and call the health system medical records office. |
| Recent vaccine | The dose may not have been reported or matched yet. | Ask the provider or pharmacy that gave the dose to verify reporting. |

Out-of-State Vaccine 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 administered, 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 contactsIf you moved from another country, keep the original vaccine record, translation if needed, and provider details. A school, college, employer, civil surgeon, provider, or public health agency may need to review vaccine names, dates, spacing, and accepted proof format.
Use the original state registry first, then bring proof to Colorado if needed.

Titer Tests When Colorado Vaccine Records Are Lost
A titer is a blood test that may show immunity to certain diseases. It can help for some healthcare jobs, college programs, clinical placements, or immigration medical exams, but the organization asking for proof decides whether titers are accepted.
| Situation | Titers may help with | Ask before paying |
|---|---|---|
| Healthcare job | MMR, varicella, hepatitis B. | Ask occupational health which lab result format it accepts. |
| Nursing or medical school | MMR, varicella, hepatitis B. | Ask if positive IgG titers replace vaccine dates. |
| Immigration exam | Civil surgeon-reviewed proof. | Ask the civil surgeon first. |
| Child care or K-12 | Limited situations only. | Follow CDPHE, school, provider, or public health instructions. |
