How to read a rabies vaccination certificate

The seven things to find

Most US and Canadian rabies certificates follow the NASPHV Form 51 layout or something close to it. Wherever the boxes sit, look for these:

1. The animal. Name, species, breed, sex, age or date of birth, color/markings. Does it match the animal in front of you? A certificate for “Bella, black Labrador, 4 years” does not cover the tan spaniel on the leash, however nice the owner is.
2. The owner. Name and address. Should match the person booking.
3. Date vaccinated (“date administered”). The one date everything else depends on.
4. Product and duration. The vaccine's name or manufacturer, and whether it is a 1-year or 3-year product. A puppy's first rabies dose is legally a 1-year dose almost everywhere, whatever the vial says; the 3-year duration applies to boosters given after that first one.
5. Date due / expires. Printed by the clinic. This is the date VaxCheck records and reminds on. If it is missing, do not work one out. A duration printed on a vial is a manufacturer's label, not a statement about this animal, and a date you calculated will be read later as a date the clinic gave you. Record the certificate with no due date, set the vaccine in your own door policy (“rabies counts for 12 months here”), and let the shop's rule — which is yours to defend — decide when the pet is due. If you need the real date, ask the clinic.
6. Tag number and lot/serial. The rabies tag number ties the paper to the metal tag on the collar; the lot number is what a clinic checks if there is ever a question about the batch.
7. The veterinarian. Printed name, license number, clinic, and a signature (ink or electronic). A certificate with no vet, no license number or no signature is a receipt, not a certificate.

Red flags at the counter

• An expiry more than three years after the date given. No rabies vaccine licensed for dogs or cats in the US or Canada is labelled for longer.
• A 3-year expiry on a puppy's first dose. Ask which dose this was.
• Dates in different handwriting or ink from the rest of the form, or a due date that has been written over.
• A photocopy of a photocopy with the vet block cut off.
• A titer result presented as a vaccination. A titer measures antibodies; many jurisdictions and most shops do not accept it in place of a rabies dose. VaxCheck records titers as titers, marked as such.

A red flag is a reason to ask, not a verdict. Call the clinic, or use VaxCheck's ask-the-clinic-to-confirm button, which emails the clinic on the certificate a one-click page to say whether the record matches theirs.

What a certificate cannot prove

Whether it is genuine. A photocopy, a photo or a PDF can be edited, and nobody at a counter can tell a careful forgery from the real thing. What a counter can do is check that the paper is complete, that the dates make sense, that the animal matches, and — when it matters — ask the clinic. That is the whole reason VaxCheck labels every record with how we know: typed by the owner, typed by staff, certificate on file, sent by the clinic, or confirmed by the clinic. The label is honest about which of those it is; nothing on VaxCheck is ever “verified by VaxCheck”.

Keep the paper attached to the dates

Whatever you type from a certificate, photograph the certificate too. On VaxCheck the picture stays filed against the record, so the row reads certificate on file rather than somebody typed this — and the next person who asks where a date came from can look instead of taking your word for it. From the same record you can ask the clinic printed on that certificate to confirm it, in one click, and their answer lands on the record in their name.
