Lost or Expired Vaccination Certificate? How to Replace Your Yellow Card (ICVP)

If you've read our guides on yellow fever certificates, meningitis and the Hajj/Umrah requirement, or polio certificate rules, you've seen the same document come up again and again: the ICVP. This post is the one we keep pointing to from all three — what the certificate actually is, and exactly what to do if yours is lost, damaged, or you're not sure it's still valid, ideally well before you're standing at a border finding out the hard way.

What the ICVP actually is

The International Certificate of Vaccination or Prophylaxis — commonly nicknamed the "yellow card" because of its traditional yellow booklet cover — is a World Health Organization-standardised document used to prove specific vaccinations under the International Health Regulations, a binding framework that close to 200 countries operate under. Currently, yellow fever is the primary vaccination formally documented on the ICVP, though the same document format is used more broadly by some countries and providers to record other travel-relevant vaccinations, including the polio and meningitis requirements we've covered elsewhere.

A few structural facts worth knowing:

• The ICVP must be issued by a designated, certified vaccination centre — not just any doctor's office. In the US, state and territorial health departments certify providers and issue them an official "uniform stamp," without which a certificate isn't valid.
• It must carry an original handwritten signature from the administering provider — a signature stamp isn't accepted — plus the vaccine manufacturer, batch number, and the official uniform stamp of the issuing centre.
• For yellow fever specifically, a single documented dose is now considered valid for the lifetime of the vaccinated person — a change formalised in 2016. Countries cannot lawfully require revaccination or a booster on the grounds that more than 10 years have passed since your original vaccination date, even if your physical card shows an old 10-year expiry format from before the rule changed.

What to do if your certificate is lost or damaged

The reassuring part: you almost never need to be revaccinated just because you lost the paper. If there's an accurate medical record of your original vaccination, a currently active, certified vaccination centre can typically issue a replacement.

Steps to take:

1. Contact the clinic or centre that originally vaccinated you first. They're the primary holder of your vaccination record and, in most cases, the fastest route to a replacement — many clinics can reissue a certificate for a small administrative fee, often without requiring a new consultation or revaccination.
2. If you can't reach the original provider (it's closed, you've moved, or you can't recall exactly where you were vaccinated), a different certified yellow fever vaccination centre may still be able to help if you have any supporting documentation — old boarding passes or receipts confirming the date and location, a photo of your original card, or a national immunisation registry record, where your country maintains one.
3. Bring whatever proof you still have to your appointment: a photo of the original certificate (even a photo on your phone can help verify the clinician's signature and stamp), the approximate date of vaccination, and the vaccine batch number if you know it.
4. If no record can be found at all, revaccination is generally the fallback — not because your original immunity has lapsed, but because there's no way to formally document it. Given a single yellow fever dose is understood to confer lifelong immunity, an unnecessary revaccination isn't medically harmful, just an avoidable extra step.

A replacement certificate issued this way should still show your original vaccination date — not the date of reissue — and, for yellow fever, should note it's valid for the life of the vaccinated person, regardless of what the original card's format implied.

Name changes: a related, often-missed scenario

Certificate replacement isn't only for lost or damaged cards — if your legal name has changed (marriage, divorce, gender transition, or any other reason) since you were vaccinated, your ICVP needs to match the name on your current passport exactly. This is the same replacement process: contact a certified centre, bring proof of both your original vaccination and your name change, and get a reissued certificate reflecting your current legal name.

How to avoid this problem next time

• Photograph or scan your ICVP as soon as you receive it, and keep the image somewhere genuinely accessible while travelling (cloud storage, email to yourself, a password manager's file attachment) — not just a photo trapped on a phone that could itself get lost or damaged.
• Keep a note of the basics even without the photo: approximate vaccination date, the name and location of the clinic, and if possible, the vaccine batch number — this alone significantly speeds up a replacement request.
• Carry the physical original in your hand luggage, not checked baggage, for any trip where it might be checked at a border — this is standard advice across all three of our certificate posts (yellow fever, meningitis, polio) for a reason: border officials expect to see it on the spot.

Getting it sorted

If you're not sure whether your certificate is still valid, whether your destination even requires one, or how to track down a replacement, this is exactly the kind of question worth raising directly with a certified provider rather than guessing. Check destination-specific certificate requirements using the Travel Vaccine Map tool, and use Find a Clinic to locate a certified yellow fever vaccination centre near you.
