However first, let’s brush up on our data concerning the rabies virus itself.
Rabies Virus in Cats
The rabies virus can have an effect on any mammalian species and is transmitted by means of the saliva, normally by means of a chew, though contact with an open wound may result in an infection. Curiously, though cats are probably the most generally reported rabid species in the US, there aren’t any recorded instances of cat-to-cat transmission of the illness.
The virus assaults the nervous system, producing indicators resembling:
- Inappetence
- Irritability
- Hiding
- Nervousness
- Aggression
- Wild animals might lose their concern of people
The illness will normally progress into two varieties:
- Livid (additionally referred to as “mad canine”) rabies, which incorporates pupil dilation, overt aggression, and attacking with the tooth and claws at slight provocation or loud noise.
- Paralytic (additionally referred to as “dumb”) rabies, which incorporates paralysis of throat and jaw muscle mass, extreme salivation and incapacity to swallow, and lack of muscle management. These animals hardly ever chew, however people can turn out to be contaminated when analyzing the mouth.
Prognosis may be very tough, with definitive prognosis requiring autopsy examination of mind tissue. Moreover, rabies can mimic a number of totally different illnesses.
Unvaccinated cats suspected of being contaminated with rabies have to be euthanized instantly or saved in isolation for six months. Vaccinated cats have to be given one other vaccination dose and intently noticed for 45 days. Hybrid cats, such because the Ocicat or Savannah cats, might be vaccinated in opposition to rabies, however their vaccination standing just isn’t formally acknowledged, and if a hybrid pet bites a human, the legislation might require them to be euthanized to be examined for rabies virus.
Vaccination Is Key
With the excessive danger of transmission to people, notably in its livid type, vaccination is an important step you’ll be able to take to guard your self and your cat, no matter your state’s laws. Rabies vaccines are thought of to be extremely protecting in opposition to an infection, with vaccine failure hardly ever reported.
Based on the American Animal Hospital Affiliation (AAHA), the really helpful vaccination schedule for cats is as follows:
- First vaccination between 8 and 16 weeks
- Second vaccination inside 12 months
- Subsequent vaccinations each 3 years; nevertheless, native legal guidelines might require vaccination yearly, or each 2 years.
An animal is taken into account to be absolutely protected 28 days after the primary vaccination, and instantly following subsequent vaccinations, supplied they’re given throughout the really helpful schedule. These dates have to be strictly adhered to, notably relating to journey.
1-, 2-, or 3-12 months Vaccines—What’s the Distinction?
That is the place issues get a bit complicated, however stick with us. Firstly, we have to discuss adjuvants in vaccines.
Adjuvanted vs. Non-Adjuvanted
An adjuvant is a substance that will increase the physique’s immune response to vaccination, which is nice from a protecting viewpoint, however it’s what causes a lot of the unwanted side effects of vaccination, resembling lethargy, fever, swelling, and ache. For cats, there may be an extra danger related to adjuvanted vaccines: feline injection web site sarcoma (FISS). The vaccinations mostly implicated in FISS formation are these for feline leukemia virus (FeLV) and rabies virus.
To attempt to cut back the dangers of FISS, vaccine intervals have been altered to attenuate the dangers of sarcoma formation whereas sustaining excessive ranges of immunity, which is why most vaccines are really helpful to be given each 3 years as soon as a cat has had their preliminary booster, about 12 months after their kitten vaccination. Though there are canine research which have indicated immunity can last as long as 8 years in some people, a steadiness have to be struck between minimizing the potential dangers of antagonistic vaccine reactions and public well being implications.
A further step has been taken by the corporate Purevax, which makes use of a recombinant canarypox virus to soundly confer immunity in opposition to FeLV and rabies, with out the necessity for an adjuvant. The FeLV vaccine is at present solely licensed for annual vaccination intervals, however within the UK, the rabies vaccine is licensed for 3-yearly re-vaccination, following the booster given 12 months after the first vaccination.
Within the US, there are two variations of the Purevax rabies vaccine: a 1-year and a 3-year injection, with the one distinction being the labeling. Based mostly on the differing legal guidelines that exist in several US areas, we will solely assume that the 2 formulations have been created to make it simpler for vets to adjust to this laws. Nevertheless, there are instances the place vets are solely utilizing the 1-year formulation, mistakenly believing that it supplies higher safety than the 3-yearly vaccine.
So, Which Vaccine Is Higher?
Given the excessive degree of safety given by the non-adjuvanted Purevax rabies 3-year vaccine, there appears to be little question that that is the clear winner by way of minimizing dangers whereas protecting your cat and household protected. Nevertheless, for cats which have a well being situation or are immunocompromised, an adjuvanted vaccine might present higher safety, as non-adjuvanted vaccines depend on a powerful immune response to supply future safety.
Apart from California, which requires cats to be vaccinated each 2 years after their preliminary course, vaccination necessities within the US look like in accordance with the product getting used. Nevertheless, it is very important examine along with your native authorities physique to make sure that you’re complying with their legal guidelines.
Most veterinary clinics will solely carry one or two vaccine manufacturers, so you could have to telephone round to seek out one which makes use of the vaccine you like, following the schedule set out by the AAHA. Discuss to your vet about their suggestions and expertise, as there could also be different geographic and particular person components to think about.

Lots of the issues of the previous relating to antagonistic reactions to vaccines, notably with regard to cats, have been considerably decreased by means of altering vaccine schedules and the creation of a dependable, non-adjuvanted model of the rabies vaccine. In contrast to the non-adjuvanted FeLV vaccine, the Purevax rabies vaccine is definitely licensed for a 3-yearly dosing, giving a great compromise between minimizing unwanted side effects and maximizing safety. Remember {that a} non-adjuvanted vaccine is probably not applicable for cats with well being circumstances or compromised immune methods.
