AAVSB Preventive Medicine and Vaccination Protocols 2 — Questions and Answers
Question 1: A 3-year-old indoor/outdoor cat with unknown vaccine history presents for a wellness exam. Which vaccine should be administered based on AAFP core guidelines?
- FeLV only
- Rabies and FVRCP (Correct answer)
- FIV only
- Chlamydia felis only
Correct answer: Rabies and FVRCP
Rabies and FVRCP are AAFP core vaccines for all cats regardless of lifestyle; their administration is appropriate even with unknown history.
Question 2: Which biosecurity measure is most important to prevent parvovirus spread in a shelter environment?
- Routine deworming of all incoming animals
- Immediate vaccination of all incoming animals before housing
- Separation of unvaccinated animals and regular disinfection with sodium hypochlorite (Correct answer)
- Administration of antiviral medications prophylactically
Correct answer: Separation of unvaccinated animals and regular disinfection with sodium hypochlorite
Parvovirus is extremely environmentally stable; separation of susceptible animals and bleach disinfection are critical biosecurity measures.
Question 3: What interval is recommended for the rabies vaccine booster after the initial dose in adult dogs in the US?
- 6 months
- 1 year, then every 1 or 3 years per product label (Correct answer)
- Every 6 months
- Every 5 years
Correct answer: 1 year, then every 1 or 3 years per product label
Following the initial dose, rabies booster is given at 1 year, then either annually or every 3 years depending on the vaccine product label and local law.
Question 4: Which equine disease is considered a 'risk-based' vaccine by AAEP, recommended only for horses with geographic or exposure risk?
- Tetanus
- Eastern equine encephalomyelitis (EEE)
- West Nile virus
- Potomac horse fever (Correct answer)
Correct answer: Potomac horse fever
Potomac horse fever (Neorickettsia risticii) is an AAEP risk-based vaccine because its geographic distribution and incidence vary significantly.
Question 5: A herd of swine is experiencing outbreaks of porcine reproductive and respiratory syndrome (PRRS). Which preventive strategy is most commonly used?
- Modified live virus (MLV) vaccination of replacement gilts (Correct answer)
- Water acidification only
- Antibiotic prophylaxis with penicillin
- Slaughter of all seropositive animals
Correct answer: Modified live virus (MLV) vaccination of replacement gilts
Modified live PRRS vaccines are the most widely used tool to reduce clinical disease in naive replacement gilts entering PRRS-positive herds.
Question 6: Which AVMA-recommended practice prevents the transmission of Salmonella in veterinary clinics treating reptiles?
- Routine antibiotic treatment of all incoming reptiles
- Zoonotic disease disclosure and mandatory hand hygiene after handling (Correct answer)
- Quarantine of reptiles for 60 days minimum
- Vaccination of reptiles against Salmonella
Correct answer: Zoonotic disease disclosure and mandatory hand hygiene after handling
Because Salmonella is a normal commensal in reptiles with no available vaccine, client education on zoonotic risk and strict hand hygiene are the primary preventive measures.
