• • Risk-Based Protection: For dogs exposed to environments with rodents, wildlife, or standing water (ponds, puddles), as L. pomona is a common circulating serovar.
  • Disease Prevention: Prevents severe illness affecting kidneys and liver, characterized by fever, lethargy, vomiting, jaundice, and acute renal/hepatic failure.
  • Recommended Serovars: Often combined in 4-way vaccines (with L. canicola, L. icterohaemorrhagiae, L. grippotyphosa) for broad protection, with annual boosters.

For Dogs

• Risk-Based Protection: For dogs exposed to environments with rodents, wildlife, or standing water (ponds, puddles), as L. pomona is a common circulating serovar.
• Disease Prevention: Prevents severe illness affecting kidneys and liver, characterized by fever, lethargy, vomiting, jaundice, and acute renal/hepatic failure.
• Recommended Serovars: Often combined in 4-way vaccines (with L. canicola, L. icterohaemorrhagiae, L. grippotyphosa) for broad protection, with annual boosters. 

For Horses

• Prevention: Vaccinates healthy horses (6 months+) against L. interrogans serovar pomona.
• Clinical Signs: Protects against equine leptospirosis, which can cause uveitis (eye inflammation), abortion, placentitis, and kidney failure.
• Schedule: Two doses for unvaccinated adults, followed by annual boosters, and also safe for foals/pregnant mares. 

• Dogs: The vaccine is typically given as a subcutaneous injection. It is often administered between the shoulder blades or in the loose skin over the shoulder.
• Cattle: It can be administered either subcutaneously (usually in the upper neck region) or intramuscularly, depending on the specific product and Beef Quality Assurance guidelines.
• Horses: For horses, the L. pomona vaccine is administered as a 1 mL intramuscular injection. 

1. Initial Dose: A single dose is given to healthy animals.
2. Booster Dose: A second dose is required 2 to 4 weeks (dogs) or 3 to 6 weeks (cattle and horses) after the first to establish immunity.
3. Annual Revaccination: Annual boosters are recommended to maintain protection, as immunity to Leptospira bacterins typically does not last beyond 12 months.
