What is Adverse Reaction to Rabies Vaccine?

Cats need to have a rabies vaccine to protect them, especially if they are outdoors and have the potential of having personal contact with other animals that could be affected with the rabies virus. In the United States, the number of reported rabies cases in cats exceeds the number of cases in dogs. Rabies is a major health concern since it is able to be passed between species and to humans. 

In most states, it is mandatory for your cat to have the rabies vaccine. Some counties allow for a three year vaccine to be given while others require a yearly vaccine. Be sure to research your county’s laws regarding vaccinations for your cat. If you are unsure about what vaccinations are required by law for your cat, contact your veterinarian for assistance.

Generally, if your cat has a reaction to the rabies vaccine it will be minor. There have been cases, though, where the reaction is life threatening. When your veterinarian administers the rabies vaccination to your cat, be sure to watch your cat closely for several hours for any signs of having an adverse or allergic reaction.

Symptoms of Adverse Reaction to Rabies Vaccine in Cats

Your cat may exhibit mild symptoms of an adverse or allergic reaction to the rabies vaccine. Those symptoms will generally lessen over a few days and then disappear. Your cat may also develop serious symptoms from their vaccine that will need definite veterinary intervention and treatment. If you notice any of these symptoms, mild or severe, contact your veterinarian for an immediate appointment. 

Symptoms of a mild reaction or allergy to the rabies vaccine in cats include:

  • Vomiting
  • Swelling at the injection site
  • Pain at or near the injection site
  • Fever (low grade)
  • Diarrhea
  • Appetite loss
  • Lethargy
  • Itching 
  • Sneezing 

Symptoms of a serious reaction to the rabies vaccine in cats include: 

Vaccine Associated Fibrosarcoma

This is the development of a cancerous tumor at the injection site. The tumor can develop from a few weeks to a year after the vaccination has been given.

Organ Damage

The protein that is in the rabies vaccine can potentially damage your cat’s kidneys, liver and/or central nervous system. Organ damage can occur up to 45 days after the vaccination has been given. 

Anaphylactic Shock

Immediate veterinary care is required if your cat experiences anaphylactic shock, death can occur quickly without prompt treatment. Symptoms of anaphylactic shock include facial swelling, difficulty breathing, coma, seizures, 

Vaccine Induced Rabies

This is extremely rare and only can occur with the live-virus vaccine. Cats will show symptoms within 14 days of the vaccine being administered.

Causes of Adverse Reaction to Rabies Vaccine in Cats

An adverse reaction will occur when your cat is exposed to some form of allergen, in this case, something within the rabies vaccine, and its immune system begins attacking itself. Many times when a cat has a rabies vaccine reaction, it is from the live virus vaccine or from the chemical compounds that are added into the vaccine so they are more effective. Another cause of having a reaction to the rabies virus can be when multiple vaccinations are given at the same time.

Diagnosis of Adverse Reaction to Rabies Vaccine in Cats

Your veterinarian will begin their assessment of your cat by asking about your cat’s medical history including any recent vaccinations, diet changes or environmental changes. They will then conduct a physical examination. A urinalysis, fecal exam, complete blood count and biochemistry panel may be completed to rule out other possible causes of the adverse reaction.

Treatment of Adverse Reaction to Rabies Vaccine in Cats

Once your veterinarian has determined the cause of your cat’s reaction, they will discuss treatment options with you. Usually, mild cases will not require treatments unless it is an antihistamine and/or corticosteroid to stop itching or sneezing. Anti-inflammatories may be given to reduce swelling. 

If your cat has developed a more serious adverse reaction or allergy to the rabies vaccine, your veterinarian will need to administer treatments. These treatments will probably be supportive care in the form of intravenous fluid therapy, oxygen therapy and close monitoring of their vital signs. 

If your cat has gone into anaphylactic shock, emergency measures will need to be taken to keep your cat’s airways open so they are able to breathe. Oxygen support will most likely be necessary. Epinephrine will be given as well as antihistamines.

Recovery of Adverse Reaction to Rabies Vaccine in Cats

Your veterinarian can help you protect your cat from developing a serious rabies vaccine allergy, or another reaction once they know that your cat is sensitive to the vaccine. Using only inactive or dead virus vaccines may help your cat not have as severe of a reaction. Also, ask your veterinarian if three year rabies vaccine will suffice or if your county requires a yearly vaccine. 

Have your veterinarian set a vaccination schedule that prevents your cat from getting more than one vaccine at a time. Prior to giving the rabies vaccine, ask your veterinarian about administering an antihistamine to reduce the allergic reaction that your cat experiences.

Rapid breathing
Rapid Breathing, no appetite

Our 15 year old Abbigail (kitty) had the 1yr rabies vaccine...this was the 23rd of January of this yr..2 weeks later she began rapid breathing, no appetite, no drinking and slept continually. Previous to this, she was very healthy. Took her to vet and they sedated her and did chest xray. Found large mass on lung and much fluid in both lungs, thus compromising her airway...is it possible that the rabies vaccine caused this? We had her euthanized on the 13th of Feb...God bless her!

I cannot say that the rabies vaccine was the cause of this mass, masses don’t appear within two weeks and it may have been an underlying condition which wouldn’t be surprising for a 15 year old cat. I understand this is a distressing time for you, but I cannot give you any specific indication to an underlying cause; rabies vaccinations have many side effects but I cannot directly link the two, necropsy would tell you more.

Thank you for your email. It is always best to treat allergic reactions quickly, including those to a vaccine, as they may resolve, but the can progress to shock. It would be best to have her seen as soon as possible, either by your veterinarian if they have an after hours number, or at an emergency clinic. They'll be able to assess and treat her to resolve her signs and make sure that she is okay. I hope all goes well with Busa!

If Rari is only sneezing and isn’t showing any other symptoms or signs of distress you can keep an eye on her; sneezing is listed as a side effect of rabies vaccination but should decrease in severity over time. There are many causes for sneezing which may include allergies, irritants, infections, foreign objects among other causes; if there is no improvement or the sneezing gets worse you should visit a Veterinarian.

Thank you for your email. Cats can't get Rabies from the vaccine, no - it is a killed form of the virus. Some cats an have reactions to the vaccine, and feel feverish for a day or two afterwards. If he is not eating or drinking water, your veterinarian can provide treatment for him so that he feels better. Make sure that you mention this reaction the next time he has vaccines, as they need to know that he did have a reaction to it.

Thank you for your email. Rabies is a human health concern, and is present at some level in most states. There have been many instances where a rabid animal gained access to a house, or a cat accidentaly got outside, and were exposed to Rabies. By law in most states, you need to have your pet vaccinated for Rabies. Even though he doesn't go outside, he should be vaccinated for it. Most Rabies are now licensed for 3 years - check with your veterinarian as to whether he is covered under that 3 year license, or if he does need to be vaccinated. I hope that everything goes well for him.

My cat got her first rabies shot two and a half weeks ago. Today as I was loving on her I felt a spot in her side. She immediately meowed (a painful type meow; not her normal meow.) I got her to settle down and on her left shoulder area there is a red sore the size of a pencil eraser with a raised ring of skin around it. I think this is where the rabies vaccine was injected. Have you heard of this before?

Dr. Michele King, DVM
Dr. Michele King, DVM

Thank you for your email. Vaccines can cause local reactions under the skin, and they can be sore for a couple of weeks. Since I don't have access to her records, I'm not sure if that shoulder was where the vaccine was given, but it is possible that it is related. If so, those reactions typically do resolve over 2-3 weeks. Since she does seem sore, and you're not sure that that is where the vaccine was given, it would be a good idea to have her examined, as vaccines can also cause more serious reactions. Your veterinarian will be able to assess the area, look back in her records to see if that was where her vaccine was given, and decide an appropriate course of treatment, if needed. I hope that Clio does well.

I have two Male cats that had rabies vaccination Friday afternoon. Early Saturday they both started vomiting. Would eat but could not keep down food. Took them into the vet on Monday. Vet was convinced that they had gotten into something so blood work was done. No toxins came back in blood panel. They gave them injections to calm their stomachs as well as fluids. They have not vomited in over 24 hrs but today they are not wanting to eat. I have tried soft food and they lick the gravy off and they won't touch the hard food. Any suggestions?

Thank you for your email. I'm sorry that happened to your cats, it is unusual but not impossible for them to have a reaction to the Rabies vaccine - is it very strange that it happened to both of them. If they will eat the soft food, you can continue to offer forms of that to them until their appetites are back for the hard food. If they continue to refuse to eat, they should be rechecked at your veterinarian, as they may need continued supportive care. I hope that they are both okay.

I had two feral cats neutered at humane society 2 weeks ago along with rabies vaccine. Seemed ok for the first week and then both started to back away from food. I caught one of the cats today and put him in a cage in the garage. He is salivating and very lethargic. The rabies vaccine was a killed virus. I wonder if he has been poisoned. I am going to keep him isolated. I wish there was more that I could do. could this be from the rabies vaccine?

Dr. Michele King, DVM
Dr. Michele King, DVM

Thank you for your email. It is very unlikely that the signs that he is diplaying are related to the Rabies vaccine. I would be careful, however - without knowing any history on these cats, it is hard to know what might be wrong with them. It would be a good idea to take them back to the shelter for an exam and possible quarantine - there are many infectious diseases that he may be affected by, but if he wasn't at the shelter for very long and just got his Rabies vaccine 2 weeks ago, he could still have been harboring Rabies. Please do not let him bite or scratch you, and it woul dbe a good idea to take him back for observation/exam to the shelter.

thankyou for replying to my question. the shelter does not do follow up on these feral cats. I have the option of euthanasia. I have him in my garage and have been able
to get him to eat. I think this is a virus, possibly when he was neutered. He is being kept warm and contained. This all I am able to do. My concern is my beautiful cat who has eosinophil granuloma complex and does not have any vaccines, so am doing my best to keep everything sterile. thank you for taking the time to respond

Thanks for contacting us about Krum. That doesn't sound like a typical reaction to vaccines - sometimes animals experience a little soreness at the area of the injection, or get a little fever. MOre sever reactions can include a swollen face or collapse. I'm not sure that the spasms are related to the vaccine, unless he is painful and that is how he is showing it. It would be a good idea to have him rechecked at his vet to make sure that there isn't anything else going on and that he is okay.

aggressive

Hi, we have rescued an injured stray cat. Before we adopt it, how do we assure ourselves this feline is safe? This cat had been a bit aggressive lately and bitten several people when they tried to catch it just so they can bring it home to nurse its injury.

I checked with our local vet and was told that if we send the cat for rabies test, it would mean euthanizing the cat. Sobs. But if we don't do the test, we don't feel safe adopting the cat, plus, we need to protect the few people it had bitten. The people had since taken rabies and tetanus jabs. The pet shop owner said the cat doesn't show symptoms of rabies currently but we never know, as the incubation period can be up to a year.

My question is, if the cat is already a carrier of the rabies virus, what will happen if we give it a rabies vaccine shot? The pet shop owner told us if the cat is infected, and upon given the vaccine, it will die. Is this true? I am thinking whether we can use the vaccine to 'test' for rabies instead of euthanizing the cat, If the cat is infected, upon given the vaccine, it will die, but in any case, it will die because of its infection. If the cat is not infected, then by giving the vaccine serves it well towards its adoption. Am I right to say that by giving the rabies vaccine to the cat will both answer our question if the cat is infected/carrier of rabies virus, plus it helps if the cat is to be adopted. Thank you very much for your valuable help.

Gina, thank you for contacting us about this stray cat. Vaccinating him for Rabies won't kill him if he is infected with the Rabies virus. It is true that an animal can be infected with Rabies for quite some time without showing signs, but if the cat is aggressive because it is showing signs of Rabies, the time frame to severe signs and death from the disease is less than 10 days. Typically, we quarantine animals for 10 days if they have bitten and we are concerned about Rabies. With this cat, there would be no harm in having it vaccinated to prevent Rabies if it hasn't ever been vaccinated. In the meantime, avoid getting bitten or scratched by the cat if possible!

I have 3 kittens who are 18 weeks right now. They are not on any other medications, and have not gotten into anything as far as cleaning products, other foods etc... at least to my knowledge. They just got their Rabies shot last Friday November 24th. Since then they have all been super lethargic and two of them will not eat anything, what so ever. However they will drink water occasionally in little amounts. Also as of last night they all have become more playful but the two are still not eating. I came home from work today and the two who aren’t earing vomited but it was just liquid. I called my vet twice today, once this morning, and this afternoon once I got home after the vomiting episode. This morning they said to keep an eye on them because they should be snapping out of it from the vaccines. This afternoon they said they wanted me to bring them in. However, I have no extra money laying around for exams right now. So again they said to just keep an eye on them. I want to know if these behaviors could be because of the vaccines still? What is the common time frame to have a reaction to vaccines? And how long is too long to wait, will it be detrimental to wait this long by just “keeping and eye on them”?

Thank you.

Lethargy is a common reaction to the rabies vaccine especially in younger animals, it is important to keep an eye on them and it is more important to keep them hydrated than them having food; vomiting fluid is ‘normal’ when the stomach is empty due to acid accumulation. This lethargy may last a week and a bit which I understand is a stressful time for you, but please make sure that they are hydrated and try to encourage eating with something appetising like tuna or similar.

Hello, I requested a rabies vaccination for my 10 year old cat at a recent vet follow up appt (regarding a urinary issue which has resolved). She is fractious and an indoors cat, and I avoid unnecessary vet visits for this reason, but opted for thr rabies vacc since it is required by most apartments. Her appt was about 4 weeks ago, and last week I noticed she developed a lump in her back right hip area. I googled and found out about sarcomas which concerned me. I called the vet and they advised the reaction is common (though it appeared 3 weeks later?) A couple days ago, she's been having off and on appetite loss, vomited once, and has had diarrhea today. She received an excellent, healthy report from her appt and has otherwise been healthy. I am concerned something is seriously wrong but because of her aggressive nature, I want to wait til her actual vet office is open since they know her history and are familiar with handling her (she has to be sedated to be seen and I hate that). Any advice?

My cat is 10 Year’s old and had Rabies vaccine ( last one was 3 years ago) and FVRCPC 4 days ago. Since we brought her back , she is very lethargic, walks very slow ( one of her front leg seems like is hurting) and not sure if the legs on the back are ok also: walk very slow and she has problems getting up in our bed- no strength- which is all new. She was a very active cat. She feels traumatized and even afraid of us. When she walks, she walks along the walls more .... So far she eats soft food and goes to the bathroom . She sleeps all day and night ; just gets up to eat and go to the bathroom. How long the symptoms at the injection site can last ?( she is only used to us, so probably she fought a lot at the Vet when they gave her the vaccine ) . How long this lethargy or side effects from these 2 vaccine can last ? I saw that other cats had paralyzed legs... this can still happen to my cat also ? How would I know if her kidneys and liver , or nervous system are affected ? Would these side effects can still appear after these 4 days from the vaccination ? She had no anesthesia given or other meds. The producer for the Rabies vaccine is : Zoetis and the type is : Killed virus.Product name: Defensor 3 Rabies Vaccine.

Sometimes cats can feel a little bit groggy from the vaccine as it provokes an immune system response just like when they are sick, some animals respond well whilst others may be lethargic for a week or so; many times it is due to the rabies vaccines, but one week of lethargy every three years compared with a rabies infection is worth it in my opinion. Ride it out, but if Joy is feeling the same on Friday, just check in with your Veterinarian to be on the safe side. Regards Dr Callum Turner DVM

Thank you very much for your response . She seems a bit better this morning ( cleaned herself a bit and attempted a stretch ). She continues to eat and drink water, but still very slow in movements and weak . Will monitor her for now . Thank you , Sorina

Were the vaccination and sedation done by a Veterinarian? It is difficult to know how long the effects of sedation will last because it depends on which specific meds were given to sedate Boo. Generally most cases like this will resolve overnight but if there is no improvement by morning you should visit your Veterinarian for a check. Regards Dr Callum Turner DVM

leg is paralyzed

My friends cat had a rabies vaccine and now her leg is totally paralyzed! I go to the same vets.
They told her the cats leg needs to be amputated.Is this the only option? And is this common?
I'm afraid to take my cat back for his rabies shot.

Paralysis induced by a modified live rabies vaccines has been documented, cases usually do not resolve; I would recommend discussing the case with your Veterinarian or visiting another Veterinarian for another opinion. Another course of action would be to speak with the manufacturer of the vaccine for more specific information about other cases reported back. As for your own cat, if you live in an area affected by rabies (few countries are rabies free) it would be best to have your cat vaccinated as the benefits outweigh any risks. Regards Dr Callum Turner DVM

I've had many animals have rabies shots and the two cats i have now receive the shot once a year never any reactions. I feel like that was a fluke reaction. I'd never miss a vaccine especially this one a mouse could wander into your house and give your pets rabies or they could be bitten by a carrier animal at the vets office you just never know. I'd just find a different vet maybe.

It is difficult to say what specifically is going on here, sometimes cats will have reactions to vaccines which may result in a decrease in appetite and lethargy; if there is some suspicion that something isn’t right with his liver or kidneys, blood tests should be taken to look at function to see if any medical management or dietary changes are needed. Regards Dr Callum Turner DVM

How do you find out if my cat was also exposed to a bad batch of vaccine?

After my cat received a rabbits shot, he was slowly dieing over a 1 year time period and most of it was hospitalization at my Vet.. Nothing can be done. My Vet just informed me the manufacturer "MER" has announced that it was a bad batch of vaccines and they take full responsibility
For all ailments of cats and deaths and are reimbursing anyone with a cat that had major vet bills. That's fine and all but I would much rather have my beautiful Blue Point Himalayan back to his very healthy & loving self. Please people be very cautious and really think it over before making that decision to give your kitty a rabbies vaccine.I blame myself for giving him this slow death cycle. He was always a indoor cat and he definitely didn't need that rabbies vaccine. If only I could go back and redo it all over again.

If Mercy is having a severe reaction again to the rabies vaccine, you should return to your Veterinarian especially if the swelling is interfering with her breathing; apart from Benadryl which was given already there is nothing else over the counter I can recommend for you given the circumstances.
