If a vet’s office, boarding kennel, groomer, or pet insurance form ever asked you for the name of your dog’s rabies vaccine, you probably had to dig. The paperwork usually says something like “1-year rabies” or “3-year rabies,” and the brand is buried in a lot number or a sticker nobody reads aloud. That is a very common moment, and there are only a handful of names to know.
This guide covers the licensed rabies vaccines for dogs in the United States, what the digits and letters in their names mean, and how to check what your own dog received. It also covers the one name that trips people up most, because it looks like a dog vaccine and is not.
Your veterinarian should confirm the product used for your dog. The list below is a starting point for reading a record, not a substitute for their advice.

Rabies vaccines approved for dogs in the US
Dog rabies vaccines are all killed vaccines. The AAHA canine vaccination guidelines put it plainly: every rabies vaccine licensed for dogs is inactivated, and only 1-year and 3-year formulations exist. There is no modified-live or recombinant option on the canine menu in the US.
Four manufacturers sell canine rabies vaccines. Here are the eleven product names licensed in the US, pulled from this compiled list of approved rabies vaccines, which lists the labeled duration, manufacturer, dose, route, and earliest age for each one.
| Product name | Manufacturer | Type | Labeled duration |
|---|---|---|---|
| IMRAB 1 | Boehringer Ingelheim | Killed, adjuvanted | 1 year |
| IMRAB 1 TF | Boehringer Ingelheim | Killed, adjuvanted | 1 year |
| IMRAB 3 | Boehringer Ingelheim | Killed, adjuvanted | 3 years |
| IMRAB 3 TF | Boehringer Ingelheim | Killed, adjuvanted | 3 years |
| Nobivac 1 | Merck Animal Health | Killed, adjuvanted | 1 year |
| Nobivac 3 | Merck Animal Health | Killed, adjuvanted | 3 years |
| Nobivac 3 CA | Merck Animal Health | Killed, adjuvanted | 3 years, California only |
| Rabvac 1 | Elanco Animal Health | Killed, adjuvanted | 1 year |
| Rabvac 3 | Elanco Animal Health | Killed, adjuvanted | 3 years |
| Vanguard Rabies 1 | Zoetis | Killed, adjuvanted | 1 year |
| Vanguard Rabies 3 | Zoetis | Killed, adjuvanted | 3 years |
Every product on that list is licensed for dogs at least 3 months of age. Ten are sold nationwide. Nobivac 3 CA is labeled for use in California only, so if you see that suffix anywhere but California, something is off about the record.
If a clinic has any other rabies product on the shelf, ask what it is. It is either a cat product, a product from another country, or something your dog does not need for US licensing.
What the numbers and letters in the names mean
The naming convention is tidy once you see it. The word before the number tells you nothing useful. The number tells you how long the label says protection lasts.
The 1 and the 3. A “1” means the product is labeled for one year of immunity. A “3” means three years. Both are legally recognized duration-of-immunity options in the US. Which one your dog gets depends on your state law, your clinic, and your dog’s age at the first shot.
The TF. TF stands for thimerosal free. Boehringer Ingelheim sells thimerosal-free versions of both IMRAB products. Thimerosal is a preservative that keeps a vial from degrading once the clinic opens it, and the TF versions exist mainly so clinics that avoid the preservative can still use that brand. You can see the full lineup on the manufacturer’s IMRAB page.
The CA. Nobivac 3 CA is the California-labeled version. The rest of Nobivac 3 is the national version. Nobody outside California needs to read that suffix twice.
The 1-year booster is still recommended. This is the part that surprises people. The AAHA guidelines recommend a booster one year after the initial rabies vaccination no matter which formulation the dog got. The stated purpose is to immunize the rare dog that did not respond to the first dose. After that booster, subsequent doses can fall on the 3-year interval where local law allows it.
The cat vaccine that gets mistaken for a dog vaccine
PureVax Rabies is a real rabies vaccine from Boehringer Ingelheim, and it is a good one. It is also labeled for cats only. It is recombinant and nonadjuvanted, which makes it the odd one out on this whole page, and it does not count for a dog’s US rabies vaccination.
So if you are searching for a rabies vaccine name for your dog and PureVax comes up, you are probably looking at a cat product or at a dog owner’s misreading of a cat’s record. There is no PureVax canine rabies vaccine in the US market. Boehringer Ingelheim’s canine product is IMRAB, and it is adjuvanted, like every other dog rabies vaccine.
The only recombinant rabies vaccines sold in the US are the two PureVax cat versions. If anyone offers you one for a dog, ask them why before you accept it.
Reading a rabies certificate or vet record
If you are standing in front of a form and need the name, this is the fast path.
- Look for the product name near the top of the rabies certificate. It is usually the boldest line, sometimes with the manufacturer attached, as in “IMRAB 3, Boehringer Ingelheim.”
- Read the digit at the end. That one character tells you whether your dog is on a 1-year or 3-year record, and it tells you when the next dose is due.
- Check the age the vaccine was given. Licensed canine rabies products are labeled for dogs 3 months of age and older.
- Check the route. Most of these vaccines can go under the skin or into muscle, so that detail will not identify the brand.
- If the record shows a name that is not on the list above, photograph the whole certificate and ask the clinic. You may be looking at a lot number or a generic house label instead of a brand name.
The lot number matters for a different reason. It is how a manufacturer or health department traces a batch, and it is how your clinic answers a recall question. Keep it with the certificate.
Why the vaccine name matters beyond the vet visit
Rabies is the rare vaccination where the paperwork is legally load-bearing. The AAHA guidelines note that rabies vaccination is mandated in many jurisdictions, and that age at first shot, booster timing, formulation, and whether exemptions are even allowed are all set by law rather than by veterinary preference. Those rules can sit at the city, county, state, or provincial level, and they differ from place to place.
That is why a blank name on a record can cause real friction. Boarding facilities, daycares, groomers, travel paperwork, and licensing bureaus will usually ask which product was used, and your state health department may specify which products count for licensing. Requirements can even narrow the accepted choices in a particular state.
Rabies also does not leave room for delay. The CDC’s rabies prevention guidance reports that roughly 100,000 Americans get vaccinated after a potential exposure each year, and that fewer than ten people die of rabies in the US annually. That low death count depends on treatment starting fast. Their advice after a bite or scratch is to wash the wound with soap and water for 15 minutes, contact a health department right away, and ask the owner for proof that the pet is up to date on rabies vaccination. People who need the vaccine and skip it once symptoms start almost always die.
What to do when you cannot remember the name
You have three good options, in order of speed.
Ask your vet for the rabies certificate. Most clinics keep it in the pet’s file and can print or email it in a minute. This is the only answer that counts for licensing or boarding.
Check your own files. Look for the certificate, an invoice from the vaccination visit, a clinic portal account, or an email confirmation from the day of the shot. If you use a yearly-reminder app, you may already have the clinic name and date, which is enough for them to pull the record.
Ask your local or state health department. The CDC publishes state and local rabies contact information, and those offices know the licensing rules where you live. They will not tell you what was in your dog, but they will tell you whether the answer on your record qualifies.
A rabies tag on the collar is not a substitute. Tags often carry only a clinic number or a license number, not the product. If you have no certificate at all, treat that as an open item to resolve with your vet at the next visit, along with whether your dog needs anything else. Confirm the product with them rather than assuming, since some clinics stock more than one brand and some states steer owners toward specific products.
Frequently asked questions
Is there just one rabies vaccine for dogs?
No. There are four brands and eleven product names licensed in the US, counting the 1-year, 3-year, TF, and CA versions. Any licensed canine rabies vaccine does the job. The specific brand usually reflects what your clinic stocks, and for licensing the labeled duration and legal status matter, not the brand.
Are all dog rabies vaccines killed?
Yes. Every rabies vaccine licensed for dogs in the US is an inactivated, or killed, vaccine. The only recombinant rabies vaccines sold in the US are labeled for cats.
What is the difference between 1-year and 3-year rabies vaccine?
The digit is the labeled duration of immunity. A 3-year product means the dog is legally vaccinated for three years, not that it is stronger. Both are killed vaccines, and the AAHA guidelines recommend a booster one year after the first dose regardless of which one you started with.
Does it matter which brand my dog got?
For your dog’s health, the differences between the licensed canine products are minor. For paperwork, the name has to appear on a valid record that your state and local authorities accept. If a clinic offers you a product not on the list above, ask them to explain it.
Can I use PureVax for my dog?
No. PureVax Rabies is labeled for cats. For a dog in the US, use one of the killed canine products listed above.
What if I cannot find my dog’s rabies certificate?
Ask your vet to pull the record or reprint the certificate. Clinics keep rabies documentation because licensing and bite follow-up both depend on it. If the clinic cannot produce one, resolve it with them and your state health department rather than assuming your dog is covered.
Is a rabies vaccine safe for puppies?
Licensed canine rabies vaccines are labeled for dogs 3 months of age and older. Your veterinarian will weigh timing against the rest of the puppy vaccine schedule, and against any state licensing rule about age at the first shot, since those differ by jurisdiction.
Do I need to know the name before my dog bites someone?
No, but the name will be asked for. After a bite, the health department decides what happens next based on the dog’s rabies status and records. Keeping the certificate at home, or a photo of it, saves everyone a scramble in a stressful moment.
What to remember
The rabies vaccines licensed for dogs in the US are IMRAB 1, IMRAB 1 TF, IMRAB 3, IMRAB 3 TF, Nobivac 1, Nobivac 3, Nobivac 3 CA, Rabvac 1, Rabvac 3, Vanguard Rabies 1, and Vanguard Rabies 3. All are killed vaccines, all available in 1-year and 3-year versions, and PureVax is the cat product.
Your dog’s own record is the only one that counts for licensing, boarding, and bite follow-up. Get the certificate from your vet and keep it where you can find it. And confirm the product and schedule with your own veterinarian, since they know the rules where you live.
