Q

What are the reasons to vaccinate?

A
  • Responsible pet ownership – annually, get a full health check up
  • Having an annual check up with a vet means we can spot other clinical disease earlier
  • Maintains a healthy pet population
  • Reduces deaths
  • Reduces incidence of zoonoses
  • Validates insurance policies

Q

What is the importance of maternally derived antibodies?

A

Passive transfer of maternal immunoglobulins is VITAL for protection of the neonate against respiratory, enteric and systemic infection

Q

How do maternally derived antibodies affect vaccination?

A
  • MDA inhibit the development neonatal immunoglobulins until the maternally-derived antibodies have been degraded
  • A neonates’ immune system cannot respond effectively to vaccination until MDAs have waned off (can take several months)

Q

Describe each of the 3 types of vaccine

A
  • Modified live: contain a virus that has been modified to lose its disease-causing ability (attenuation)
  • Killed: attenuated through a process that results in their death
  • Recombinant: part of the genetic sequence of the virus/bacterium are isolated that encode immunogenic proteins in patients

Q

What is the importance of lepto being a killed vaccine?

Study These Flashcards
A

It requires annual vaccination

24
Q

What are the 2 components of kennel cough?

Study These Flashcards
A
  • Canine parainfluenza virus

- Bordetella bronchiseptica

25
Describe vaccination of canine parainfluenza
- Live attenuated injectable vaccine exists to reduce clinical signs and viral shedding – not prevention - Licensed from 8 weeks of age, recommended to give another dose 2-4 weeks later - If a dog is getting intra-nasal KC then there is no requirement for injectable vaccine
26
Describe the features of Kennel cough including: - Route of infection - Clinical signs
- ROI = inhalation (highly infectious) | - Clinical signs: sudden-onset honking goose cough, upper resp signs, tracheitis
27
Describe the onset of immunity post-vaccination for both components of kennel cough
- B. bronchiseptica immunity 72 hours post vaccination | - CPi immunity 3 weeks post vaccination
28
Herpes vaccination is only licenced in?
Pregnant bitches | - vaccinate the dam to give passive immunity to pups
29
What is the dosing schedule of the 3 herpes virus vaccinations?
First injection: Either during heat or 7 – 10 days after the presumed date of mating. Second injection: 1 to 2 weeks before the expected date of whelping. Revaccination: during each pregnancy, according to the same schedule.
30
Describe the vaccination schedule for DHP
- 1st vaccination with DHP at 6-8 weeks old - 2nd vaccination with DHP 2-4 weeks later (must be at least 10wks old) - Primary booster vaccine at 1 year old with DHP, then every 3 years
31
Describe the vaccination schedule for Lepto and KC
- Lepto initial dose at 8 weeks and then 2-4 weeks later and then annually (L4 must be 4 weeks old) - Intranasal KC given at 8 weeks then annually (sometimes left till later as a lot for 1st puppy visit, can wait until 12 weeks!)
32
What are the 3 feline core vaccines?
- Feline panleukopenia (FPV) - Feline herpes virus - Feline calicivirus
33
Which viruses are responsible for cat flu?
- Feline herpes virus | - Feline calicivirus
34
What are the two non-core feline vaccines?
- Feline leukaemia virus (FeLV) | - Rabies
35
Describe the features of Cat flu including: - Route of infection - Clinical signs
ROI = nasal, oral or conjunctival, also sharing of food bowls Clinical signs: - rhinitis, conjunctivitis, nasal discharge, sneezing
36
What are the clinical signs of feline calicivirus?
``` Chronic gingivitis/stomatitis Lingual ulceration (90% + on PCR swab) and polyarthritis/transient limp ```
37
What are the clinical signs of feline herpes virus?
- corneal ulceration, chemosis, punctate keratitis (uptake of green stain when placed in the eye)
38
Which feline core virus can produce life long carriers?
Feline herpes virus
39
Where does feline panleucopenia virus attack in the body?
- Attacks rapidly dividing cells - Intestinal epithelium → diarrhoea and vomiting as well as weight loss - No crypts in the villi so no absorption - Bone marrow → panleucopenia - Foetuses → cerebellar hypoplasia, hypermetria
40
Feline panleucopenia virus is similar to which canine virus?
Canine parvovirus -2 | Feline panleucopenia is caused by feline parvovirus
41
Describe the features of Feline leukaemia virus including: - Route of infection - Clinical signs
ROI = Primarily saliva | Clinical signs: Immunosuppression, concurrent infections, anaemia, neoplasia
42
How is feline leukaemia virus diagnosed and treated?
Diagnosis: easy SNAP test from blood (positive result in a healthy cat is suspicious, re-test 12 wks later incase of ‘regressor’ response) Treatment: supportive treatment for recurrent infections, ensure FeLV positive cats are neutered and are indoor-only
43
TriCat contains which vaccines?
Panleukopenia Herpes Calicivirus
44
Describe a feline vaccination schedule
- 9 weeks old (1st vac): TriCat (panleukopenia, herpes and calicivirus) +/- FeLV - 12 weeks old (2nd vac): TriCat +/- FeLV - 1 year old (primary booster) - TriCat +/- FeLV - 2 year old – Ducat - 3 year old – Ducat - 4 year old – TriCat +/- FeLV
45
Ducat contains which vaccines?
Herpes and Calicivirus
46
Describe the restart protocol for canine vaccines
Viral dog vaccines (DHPPi) require a single dose of vaccine to re-start Leptospirosis DOI wanes rapidly after 1 year, thus full re-start optimal Canine re-start vaccination protocol: - 1st re-start: DHPPi + L4 - 4 wks later: L4
47
What can occur at the injection site in cats?
Feline Injection Site Sarcoma
48
Describe the 3-2-1 rule for monitoring post-vaccine reaction
- 3 months: any mass at site of injection 3 mo or more after vaccination - 2cm: any mass being more than 2cm in diameter after vaccination - 1 month: any mass which increases in size 1 mo after vaccination
49
How can feline injection site sarcomas be prevented?
- Vaccinate only as frequently as necessary - Allow vaccines to reach room-temp prior to administering as may reduce inflammatory response - Vaccinate in the distal limbs as radical surgical removal easier via amputation
50
Animal health certificates are issued by?
Official veterinarians
51
Pet dog/cat/ferret can enter UK if?
- Microchipped - Has a pet passport - Has been vaccinated against rabies - Dogs had tapeworm tx (praziquantel or equivalent) 24-120 hours prior to returning to UK
52
If an animal is coming from an unlisted country what must it have alongside a rabies vaccine?
A blood titre test
53
An animal must travel within how many days of an animal health certificate being issued?
10
54
How long does an animal health certificate last?
4 months
55
What are the clinical signs of rabies?
Behavioural changes, hypersalivation → aggression/hyperexcitation → paralysis and death
56
Describe the vaccination schedule for rabies and how long after a vaccine can an animal travel?
- Vaccine takes 21 days to achieve immunity, therefore can’t travel until 21 days post vaccination - Booster every 3 years but some countries annually (check with country requirements)
