Moving States: Bring the Records Yourself
State immunization registries do not reliably follow a family across a state line. What to pull before you leave, and what to hand the new pediatrician.
Published · Updated
You are the courier. Nothing in the United States will transfer immunization records to another state on your behalf, because there is no national vaccination database: the CDC says on its own records page that it does not keep vaccination records, and sends families to their doctor, their state registry, or their child's school instead. What crosses the state line is what you carried across it.
Do immunization records transfer between states?
Not automatically. Immunization information systems are built jurisdiction by jurisdiction — the CDC defines them as confidential, population-based databases that record the doses given by participating providers inside one geographic area (CDC, Immunization Information Systems). That architecture is designed to consolidate records inside a state and to exchange data with the providers in it. It does not promise that Ohio's system has handed your child's history to Arizona's by the Tuesday you sit in a new waiting room.
So the honest planning assumption is that a new clinic will query the local registry and see a blank, or a sliver: the two doses a local pharmacy happened to report. That is not a verdict on your child's history. It is a reminder that a registry is a state instrument, and you just left the state.
The reliable move is to request each state's report yourself. The CDC publishes a state-by-state directory with a phone number, a portal, and in several states a QR code for every jurisdiction (Contacts for IIS Immunization Records). Request the outgoing state's report before the move and the incoming state's after you enroll, and treat the two as separate errands. How a state registry actually works explains why one can be complete and the other nearly empty for the same child.
What should you pull before you leave?
Do this while you still hold a working portal login and a phone number the old office recognizes.
- A complete immunization printout from every clinician, for every person in the household — not the last physical, the full history.
- The outgoing state's registry report, requested through the contact listed for that state.
- Anything given somewhere else: the pharmacy flu dose, the travel clinic visit, a workplace or school-based clinic. These are the doses a pediatric chart most often never sees.
- The portal downloads themselves, saved to a device you own, before the account goes dormant.
The CDC's page for parents, Keeping Track of Records, names the three places copies live: the doctor or clinic that gave the shot, the state immunization information system, and the child's school. All three are easier to reach from inside the state than from outside it.
Call the old office while your voice is still familiar. After the move, "we need records from 2019" becomes a medical-records request with an address they may never have had.
What does a usable handoff look like on paper?
Boring on purpose. A new electronic chart can absorb this in one sitting:
| What the new office needs | Where it comes from |
|---|---|
| Legal name and date of birth as spelled in the new chart | Your own list |
| Vaccine names and dates, written as the old clinic wrote them | Clinic printout |
| Which practice gave each dose | Clinic printout |
| Doses given outside the pediatric office | Pharmacy or travel clinic receipt |
| A registry report, marked with the state it came from | The outgoing state's IIS |
Two things belong to the clinic's document and not to your own list: product brand names and the inventory detail a clinic tracks internally. Do not retype either. A private household record — the kind an app keeps — holds people, vaccine names and dates; it is an index that tells you what to go ask for, never a substitute for the clinic's own paper.
If a date is missing, leave it missing. A clinician would rather see a gap than a confident fiction typed from memory.
What happens at the first visit in the new state?
Say out loud that you have just moved and brought records from the previous state, then hand over the printouts before anyone opens a blank form. The office enters what it can and tells you what it still cannot find.
From there the decisions are clinical. A delayed or undocumented series does not usually mean starting over: the CDC's catch-up immunization schedule for children and adolescents gives providers minimum intervals for resuming a schedule that slipped. Whether a clinician uses catch-up intervals, orders antibody testing, or waits for a fuller chart from the old practice is their call, not something to pre-decide from an article.
Ask two questions before you leave the room: does this practice report to this state's registry, and do they want the old state's report again once your child is in the system here.
What keeps leaking after you arrive?
The same leak that existed before the move, running faster because everything is new. The first local pharmacy flu shot, the urgent-care tetanus dose, the school nurse who gives a form back with a stamp nobody photographs.
Update the school or daycare with the new clinic's name in the first month. Write every new dose into your own list the day it is given. If something is still missing after both clinics and both registries have answered, work the order used for a full record rebuild: previous providers first, then the registry, then school or camp copies from the state you left. Families who move on orders rather than on a lease do this on a shorter clock — the PCS version of the same job is worth reading before the second move.
A private household copy — Vaxnext is one on-phone option, free, ad-supported, no account — helps you notice what the new portal does not show. It runs non-personalized ads and never sends vaccine entries to an ad network. It does not replace the printouts riding in the car with you.

FAQ
Can two state registries share a record directly?
Some jurisdictions have data-exchange arrangements, but the CDC describes immunization information systems as population-based databases operating inside a defined geographic area, and does not promise routine interstate transfer. Plan as though nothing moves on its own: request the outgoing state's report through the CDC's contacts directory before you leave, and ask the new practice what it can actually see.
What if a school needs proof before the first appointment?
Send the official document you already hold — the outgoing clinic's printout or the previous state's registry report — with a short note saying a local chart is being opened. Schools accept a dated official record from another state far more readily than a parent-typed grid. Do not fill in dates you cannot document to speed enrollment.
Should you request the old state's registry report again later?
Often yes. A dose given in the weeks before the move may reach the outgoing registry after you have gone, so a report pulled two months later can be more complete than the one you left with. Ask the new clinician whether a second pull is worth it before you spend the phone call.
