Feline Vaccines Flashcards
What is the update on feline injection- site sarcomas?
Occurrence of this sequela remain infrequent and idiosyncratic
What influences the quality of vaccine-induced immunity?
Patients environment, characteristics of the vaccine, pathogen and patient’s immune competence
What is the primary target population of immunization?
Kittens
What is the role of maternally derived antibodies (MDA) in terms of immunization?
MDA’s provide protection during early life but does interfere with active immunization by inhibiting IgG and neutralizing vaccine Ags
Compared to puppies, do kittens have longer or shorter immunity from MDA?
Kittens have a shorter immunity from MDA (2w earlier than puppies)
The best kitten vaccination protocol is to immunize every _____ weeks through ________ weeks of age
2-4w
16-18 wks of age
In the past, it was the standard protocol to booster vaccines at 1 year of age after the kitten vaccine series; however, recent studies demonstrated otherwise. What is the current recommendations by WSAVA?
6 months of age
When do you have to repeat kitten vaccination series?**
If more than 6w elapses between the two initial doses of the vaccines (other than rabies)
Inactivated vaccines
Safer in pregnant cats and rapid onset of immunity
Attenuated vaccines
Mimics natural immune response
Recombinant vaccines
Vaccines created through manipulation of DNA of a pathogen in the lab with reduction in pathogen virulence
Core v. non-core vaccines
Core: Recommended for cats
Non-core: Recommended based on individualized risk-benefit assessment
Core vaccines for cats
FHV-1, FCV, FPV, rabies, FeLV (in cats younger than 1)
Non-core vaccines for cats
FeLV, chlamydia felis and Bordetella Bronchiseptica
Why is FIP vaccine not generally recommended
Because it should be administered at 16 weeks but kitten are infected with corona before that
No evidence that the vaccine induces protection
Should we or not vaccinate cats with FIV/FeLV for upper respiratory infection?****
Which type of FPV + FHV + FCV is considered the first choice for upper respiratory infection?
Parenteral attenuated live vaccine
Why should the attenuated upper resp. vaccines be avoided for pregnant cats and kittens less than 4w of age?
Due to potential concern for cerebellar hypoplasia
In shelters, what’s the recommended frequency of the boosters for upper resp. vaccines?
2 weeke
Where should vets report vaccine adverse events?
Contact manufacturers of the vaccine
Then Center for Veterinary Biologics of the USDAs Animal Plant Health Inspection Service
When do vaccine adverse events occur more frequently?
Within 30 days of vaccine admin
What is the 3-2-1 rule?
Bx warranted if it remains present 3 months after vx, is large than 2 cm in diameter or increasing in size 1 month after vx
Where should we vaccinate in cats?
Distal limbs and tail
