momentary pleasure.”
Canine and Feline
Vaccines do not produce immunity in 100% of population• Should decrease severity
Protection of 70% of population sufficient if communicability is low
In general practice, 1 vaccine break constitutes a failure
Illness Fever Vaccine reaction from prior vaccine Medical therapy Age: In < 5 wks. MLV can cause disease Pregnancy, whelping, queening
• modified-live virus vaccines can lead to birth defects or abortions
Problems• hypertrophic osteodystrophy and juvenile cellulitis -
modified-live virus distemper vaccine in Weimaraners • vaccine-associated sarcomas in cats : FeLV and Rabies
MLV• Strong, long-lasting
immune response that is achieved with fewer doses
• Adjuvants are not as necessary
• Quicker immune respones
• Less chance of allergic reactions
• After it is mixed only effective 1 hour
KILLED (inactivated)• More stable in storage• Unlikely to contain
contaminating pathogens
• Unlikely to cause disease due to residual disease-causing characteristics
• Produce little to no cellular and mucosal immunity
NO VACCINE IS 100% EFFECTIVE!
Chemicals, microbial components, or mammalian proteins
Enhances the immune response to vaccine antigens
Aluminum gels/ salts
Severity of disease Transmissibility Zoonotic potential Recommended by AAHA
(American Animal Health Association)
Those vaccines that every puppy should receive; identified by vaccine experts such as the AAHA Canine Task Force•CORE VACCINES FOR CANINES INCLUDE:Canine parvovirus type 2 (CPV-2) Canine Distemper virus (CDV) rCDV: Recombinat
Canine Adenovirus type 2 (CAV-2): DAPP/DHPP
CAV-2 protects against both 1 & 2 CAV-1 causes Infectious Canine Heaptitis No CAV-1 vaccine because of anterior uveitis
Rabies virus (RV)• Killed vaccine• State/provincial/local laws
Begin: 6-9 weeks of age• Do not give vaccines earlier than 5-6 weeks
*remember maternal antibody interference Frequency: q 2-4 weeks
• May vary according to risk, vaccine End: at least one dose should be
given at age 14-16 weeks of age or older
Revaccination: at 1 year of age or 1 year after the last puppy vaccination
• Rabies vaccine is initially given at 12 wks of age– Does not need to be
boostered in 2-4 weeks, but rather within 12 months. Each subsequent rabies vaccine should be given q 3yrs.
– Rabies vaccine is the only canine vaccine requiring a minimum duration of immunity study and labeled as 1 yr or 3 yr. by the USDA.
The minimum duration of immunity for the core vaccines (except rabies) is at least 5-7 yrs. (after initial puppy set of vxns)• based on challenge and/or antibody titers
you can even have this done in your own pets to determine his/her immunity level against a particular disease.
Today, a 3 yr revaccination program has been recommended in the AAHA Canine Vaccination Guidelines for dogs and the American Association of Feline Practitioners Guidelines for cats
Following the vaccine label Veterinarians resistant to change Fear that not revaccinating will cause
the animal to become susceptible soon after one year.
Compliance with boarding kennel rules
Optional or non-core vaccines should only be given to animals that need them and only as often as needed!• Potential problems: duration of immunity is
not known, the efficacy is limited or not known
EX: Leptospirosis, Bordetella, Canine Influenza, Lyme disease, Canine coronavirus, Giardia (AAHA Guidelines do not recommend coronavirus or giardia vaccines unless they can be proven to be beneficial for a certain animal)
• New vaccines: snakebites (Crotalus sp. Toxoid, western diamonback rattlesnake), periodontal disease (porphyromonas sp.), as well as a therapeutic vaccine for treatment of canine melanomas.
*VACCINES MUST BE TAILORED TO THE INDIVIDUAL ANIMAL
-Older/younger animal vs. adult- bacterial vaccine vs. viral vaccine
– Geographic area
Begin: 8-10 weeks of age Frequency: q 2-4 weeks End: last dose at 14-16 weeks of age
Feline parvovirus (panleukopenia) Feline calicivirus Feline herpes virus (viral
rhinotracheitis) Rabies virus
• Given at 12-16 weeks of age FVRCP
FeLV (feline leukemia) FIV (feline immunodeficiency virus) Chlamydia Feline coronavirus (FIP): Reduce cs
but not prevent disease Feline Giardia Bordetella bronchiseptica Feline systemic calicivirus
• May I use smaller vaccine dose in small breeds to reduce the risk of adverse reactions?– NO- the volume (1.0ml) as recommended
by the manufacturer generally represents the minimum immunizing dose• This means that a Great Dane should receive the
same amount of vaccine as a Chihuahua
May I vaccinate pregnant pets?• It is best to avoid this. Risk to the fetuses is
a concern. Assess risk vs. benefit• Feline parvovirus cerebellar hypoplasia in
utero kitten
May I vaccinate a patient while under anesthesia?• It is best not to do this. The patient may
develop a hypersensitivity reaction that may be harder to recognize under anesthesia and may be more difficult to treat. Risk of vomiting and aspiration is higher.
May I inject a modified live intranasal Bordetella vaccine?• NO- the vaccine can cause a severe local
reaction and may even result in death (liver failure)
• Intranasal vaccines are effective against respiratory disease, form immunoglobulin A which produces quick local immunity
May I administer a modified live SQ feline FVRCP oronasally? NO• Upper respiratory infection can result• spilled on the cat's fur, and the cat licks up
the spilled vaccine Clean off the fur with alcohol use dilute bleach for spills in the environment contact the manufacturer and begin supportive
treatment, if warranted
