Hello, I’m Dr. Karyn! Learn my introduction to be taught 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 need to make it possible for the alternatives I make are primarily based on info and science, and are proper for my cats, and my scenario.
In veterinary follow, our suggestions have to be consistent with the producer tips; it merely isn’t sensible to have a large number of various choices for a large number of various situations. With that in thoughts, there are three messages I would really like all cat homeowners to take residence:
- Vaccination ABSOLUTELY saves lives.
- YOU have the ultimate say on how typically and what your cats are vaccinated towards (except rabies).
- Your selections about vaccination ought to be primarily based on FACTS, not FEARMONGERING.
I typically get requested “Is vaccination protected?” and the sincere reply is that introducing a international agent into the physique to elicit an immune response will not be 100% protected, however it’s a lot safer than leaving your pet uncovered to the dangers of contracting lethal viruses. So that you would possibly need to know:
Do I vaccinate my cats? Sure.
Do I strictly adhere to the producer tips? Not utterly.
Am I conscious that I’m taking a danger by deviating from these tips? Sure, however I base my determination on the chance components for my particular scenario.
Should you’d wish to know what influences my selections about vaccinating my cats, we’ll must get a number of the nitty gritty stuff out of the way in which. Belief me, you’ll come away feeling much more assured about making the appropriate decisions in your cats with a bit extra data below your belt.

How Does Vaccination Work – In a Nutshell
The follow of exposing people, and later, animals, to a small dose of an infectious agent to set off an immune response dates again to no less than the mid fifteenth century, presumably even sooner than that. When Smallpox was busy wiping out lots of of tens of millions of individuals around the globe, 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 have been extraordinarily excessive, nevertheless it did begin to show {that a} small dose of the virus may create sufficient of an immune response to render the affected person immune.
However it wasn’t till a person named Dr Edward Jenner (truthfully, you may’t go wherever with out listening to a few Jenner nowadays!) found that the identical immune response may very well 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 combating the viral particles, leading to a quicker, stronger assault.
If the virus is efficiently killed, the bone marrow retains producing cells that may goal that specific virus, referred to as reminiscence B and T cells. These reminiscence cells might final for months, a number of years, or a lifetime, relying on the virus and the person.
The issue 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 might find yourself with long run or everlasting well being penalties from the an infection.
That 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 typically leads to the affected person feeling unwell or displaying some delicate signs of the virus, however that is merely an indication of the immune system responding.
Right here’s the place it will get a bit extra technical.
To be able to set off a ok 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 constructing reminiscence cells, and it’s the physique’s response to this adjuvant that normally creates nearly all of unwanted effects. However, the extra powerfully the physique responds, the extra possible it’s to create a superb provide of reminiscence cells, in order that the following time the physique encounters the virus, it may well combat it off shortly and effectively.

The Greatest Situation With Feline Vaccination
Similar to with people, cats typically endure from varied unwanted 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 antagonistic vaccine reactions, the place the injection triggers an excessive allergic or systemic response, are very uncommon.
The worst potential facet impact to vaccination in cats is one thing referred to as an injection web site 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 may be plenty of unfastened pores and skin, so it’s a lot simpler to inject, in addition to extra snug and fewer nerve-racking for the cat. But when an injection web site sarcoma grows on this location, it’s tough, if not unimaginable, to utterly take away the tumor because it typically extends to the backbone.
To fight this, it has been really helpful that cats be vaccinated over a limb, as this might enable amputation if wanted to utterly take away the most cancers. However, the decrease down the limb we go, the much less unfastened pores and skin there may be, and the extra painful and nerve-racking 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 cut back the possibility of this impact.
Research have discovered that the Feline Leukemia Virus Vaccine seems to have the next danger of inducing a sarcoma, presumably attributable to the truth that the virus itself assaults the bone marrow and immune system.
One technique to cut back danger is giving leukemia vaccines each 3 years, reasonably than yearly.
One firm has created a non-adjuvanted vaccine, within the hopes that this may end in much less intense unwanted effects, however this vaccine doesn’t give a long-lasting safety as ones that include an adjuvant, so it’s alleged to be given yearly.
Threat/Profit Evaluation
That is the place your decision-making comes into play. You might want to bear in mind, and sincere, in regards to the form of dangers your cats face, and speak to your vet about how to ensure they keep protected.
Cats in breeding colonies, shelter circumstances, or that dwell outside with the next danger of interacting with different cats, ought to be vaccinated towards leukemia virus in keeping with the producer advice.
For cats residing indoors, as soon as they’ve obtained a whole major vaccination course, and I usually advocate that they’ve their kitten course, plus one a yr after, you could need to take into consideration whether or not or not they should proceed with this specific vaccination. Whereas viruses like cat flu could be transmitted via the air and on surfaces, the leukemia virus requires direct cat-to-cat contact.
Should you do determine to go down the route of not vaccinating towards leukemia virus, it’s vital that you simply guarantee any new cats coming into your private home have had both a whole vaccination course, or have been examined for the virus earlier than coming into contact along with your cat.
My cats are 100% indoor, and are now not vaccinated towards leukemia virus – they’ve zero danger of publicity. I do, nevertheless, vaccinate them towards 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 will not 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:
- Round 3% of cats in the USA and Canada are contaminated with feline leukemia.
- Feline leukemia is deadly in 80-90% of circumstances.
- The incidence of injection web site sarcoma is between 1 in 1000 and 1 in 30,000 (0.1 to 0.003%).

Are vaccines protected?
After all 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? However it’s a hell of loads safer than taking our probabilities of surviving the precise virus.
The very fact is, if we’re placing one thing into the physique to elicit a response, unwanted effects are inevitable. If a drug or vaccine claims to have zero unwanted effects, it most likely doesn’t have any therapeutic results both.
I hate that we dwell in a world the place massive pharmaceutical corporations revenue from illness, and I believe that we’re proper to do our personal analysis and ask questions.
BUT, the truth that massive pharma makes cash from vaccination, doesn’t imply that vaccination is unhealthy.
Is it actually crappy that there are those that stand to make billions from each viral outbreak? Completely! However that shouldn’t imply that we cease defending our pets.
Pure immunity would possibly work, nevertheless it solely works in case your cat survives.
