Hi, I’m Dr. Karyn! Read my introduction to study extra about me and meet my 5 hilarious cats: Clutch, Cyril, Alex, Zelda, and Zazzles.
You would possibly assume that as a vet, I’ve a reasonably inflexible stance on vaccination, however similar to you, I wish to ensure that the alternatives I make are based mostly on details and science, and are proper for my cats, and my scenario.
In veterinary apply, our suggestions should be in step with the producer pointers; it merely isn’t sensible to have a mess of various choices for a mess of various eventualities. With that in thoughts, there are three messages I would love all cat house owners to take dwelling:
- Vaccination ABSOLUTELY saves lives.
- YOU have the ultimate say on how usually and what your cats are vaccinated in opposition to (aside from rabies).
- Your choices about vaccination ought to be based mostly on FACTS, not FEARMONGERING.
I usually get requested “Is vaccination safe?” and the trustworthy reply is that introducing a overseas agent into the physique to elicit an immune response shouldn’t be 100% protected, however it’s a lot safer than leaving your pet uncovered to the dangers of contracting lethal viruses. So you would possibly wish to know:
Do I vaccinate my cats? Yes.
Do I strictly adhere to the producer pointers? Not utterly.
Am I conscious that I’m taking a danger by deviating from these pointers? Yes, however I base my choice on the danger elements for my particular scenario.
If you’d prefer to know what influences my choices about vaccinating my cats, we’ll have to get among the nitty gritty stuff out of the best way. Trust me, you’ll come away feeling much more assured about making the best decisions in your cats with a bit extra information beneath your belt.

How Does Vaccination Work – In a Nutshell
The apply of exposing people, and later, animals, to a small dose of an infectious agent to set off an immune response dates again to at the very least the mid fifteenth century, probably even sooner than that. When Smallpox was busy wiping out a whole bunch of thousands and thousands of individuals all over the world, a course of referred to as variolation emerged, the place a small quantity of the fluid from a smallpox lesion was injected right into a wholesome human. This was a dangerous process because the probabilities of creating a fulminant case of smallpox had been extraordinarily excessive, but it surely did begin to show {that a} small dose of the virus might create sufficient of an immune response to render the affected person immune.
But it wasn’t till a person named Dr Edward Jenner (truthfully, you’ll be able to’t go anyplace with out listening to a few Jenner today!) found that the identical immune response might be achieved by utilizing cowpox – a associated however a lot safer poxvirus.
How does it work?
When a virus enters the physique, it triggers the immune system to launch pathogen-fighting cells like neutrophils, monocytes, and lymphocytes (T cells and B cells). After some time, the physique begins producing lymphocytes which are extra particularly tailored to preventing the viral particles, leading to a sooner, stronger assault.
If the virus is efficiently killed, the bone marrow retains producing cells that may goal that individual virus, referred to as reminiscence B and T cells. These reminiscence cells could final for months, a number of years, or a lifetime, relying on the virus and the person.
The downside with counting on our pure immune response to a virus is that it’s a recreation of probability. We solely develop a pure immunity if we survive, and we could find yourself with long run or everlasting well being penalties from the an infection.
This is the place vaccination is available in.
A vaccine makes use of an inactive model of the virus to ‘trick’ the immune system into producing an immune response and creating reminiscence cells, with out inflicting the precise an infection. This usually ends in the affected person feeling unwell or exhibiting some delicate signs of the virus, however that is merely an indication of the immune system responding.
Here’s the place it will get a bit extra technical.
In order to set off a adequate response to the inactivated virus, most vaccines include one thing referred to as an adjuvant. This adjuvant is what actually fires up the immune system, ensuring it will get to the stage of creating reminiscence cells, and it’s the physique’s response to this adjuvant that often creates the vast majority of uncomfortable side effects. But, the extra powerfully the physique responds, the extra probably it’s to create a superb provide of reminiscence cells, in order that the following time the physique encounters the virus, it might probably struggle it off shortly and effectively.

The Biggest Issue With Feline Vaccination
Just like with people, cats usually endure from numerous uncomfortable side effects of vaccination, together with lethargy, fever, or swelling. It could be disagreeable for a day or two, however it’s an anticipated response. True hostile vaccine reactions, the place the injection triggers an excessive allergic or systemic response, are very uncommon.
The worst potential aspect impact to vaccination in cats is one thing referred to as an injection website sarcoma – a sort of malignant tumor that may kind the place a vaccination has been given. This nasty tumor requires aggressive therapy, together with surgical elimination of the mass.
Feline vaccines are historically given within the scruff, as a result of there’s a lot of free pores and skin, so it’s a lot simpler to inject, in addition to extra snug and fewer tense for the cat. But if an injection website sarcoma grows on this location, it’s troublesome, if not not possible, to utterly take away the tumor because it usually extends to the backbone.
To fight this, it has been really helpful that cats be vaccinated over a limb, as this is able to enable amputation if wanted to utterly take away the most cancers. But, the decrease down the limb we go, the much less free pores and skin there’s, and the extra painful and tense the injection turns into, so it may be a little bit of a case of weighing up the dangers and advantages, in addition to discovering different methods to scale back the prospect of this impact.
Studies have discovered that the Feline Leukemia Virus Vaccine seems to have the next danger of inducing a sarcoma, probably as a consequence of the truth that the virus itself assaults the bone marrow and immune system.
One technique to scale back danger is giving leukemia vaccines each 3 years, relatively than yearly.
One firm has created a non-adjuvanted vaccine, within the hopes that it will end in much less intense uncomfortable side effects, however this vaccine doesn’t give a long-lasting safety as ones that include an adjuvant, so it’s purported to be given yearly.
Risk/Benefit Analysis
This is the place your decision-making comes into play. You should be conscious, and trustworthy, concerning the type of dangers your cats face, and discuss to your vet about how to verify they keep protected.
Cats in breeding colonies, shelter circumstances, or that stay outside with the next danger of interacting with different cats, ought to be vaccinated in opposition to leukemia virus in response to the producer suggestion.
For cats residing indoors, as soon as they’ve obtained a whole major vaccination course, and I typically suggest that they’ve their kitten course, plus one a yr after, it’s possible you’ll wish to take into consideration whether or not or not they should proceed with this explicit vaccination. While viruses like cat flu might be transmitted by means of the air and on surfaces, the leukemia virus requires direct cat-to-cat contact.
If you do determine to go down the route of not vaccinating in opposition to leukemia virus, it is important that you simply guarantee any new cats coming into your own home have had both a whole vaccination course, or have been examined for the virus earlier than coming into contact together with your cat.
My cats are 100% indoor, and are now not vaccinated in opposition to leukemia virus – they’ve zero danger of publicity. I do, nevertheless, vaccinate them in opposition to the cat flu viruses each three years.
You could be questioning, Why danger utilizing the leukemia vaccine in any respect?
When a cat turns into contaminated with feline leukemia, there’s a window of time the place, if the virus is efficiently eradicated, the cat will survive and have gained pure immunity – Yay!
BUT, we don’t know precisely how lengthy that immunity lasts, AND if the virus shouldn’t be eradicated inside that window of time, the cat will develop feline leukemia, a debilitating illness that always results in struggling and loss of life.
A number of statistics:
- Around 3% of cats within the United States and Canada are contaminated with feline leukemia.
- Feline leukemia is deadly in 80-90% of circumstances.
- The incidence of injection website sarcoma is between 1 in 1000 and 1 in 30,000 (0.1 to 0.003%).
Protecting our pets needs to be precedence #1.
Are vaccines protected?
Of course they’re not utterly protected – we’re manipulating the immune system with an artificially altered model of a virus. Does that sound protected to you? But it’s a hell of loads safer than taking our probabilities of surviving the precise virus.
The reality is, if we’re placing one thing into the physique to elicit a response, uncomfortable side effects are inevitable. If a drug or vaccine claims to have zero uncomfortable side effects, it in all probability doesn’t have any therapeutic results both.
I hate that we stay in a world the place huge pharmaceutical firms revenue from illness, and I feel that we’re proper to do our personal analysis and ask questions.
BUT, the truth that huge pharma makes cash from vaccination, doesn’t imply that vaccination is dangerous.
Is it actually crappy that there are those who stand to make billions from each viral outbreak? Absolutely! But that shouldn’t imply that we cease defending our pets.
Natural immunity would possibly work, but it surely solely works in case your cat survives.
