What is the leptospirosis vaccine?

The leptospirosis vaccine prevents dogs from contacting infections from Leptospira bacteria, which are commonly found in soil and water, according to the American Veterinary Medical Association. The vaccine provides protection for at least 12 months. Veterinarians recommend that at-risk dogs receive the vaccination on an annual basis.

Leptospirosis can be spread from dogs to humans as well, as the American Veterinary Medical Association details. Avoiding contact with a dog's urine reduces the risk of humans contacting the bacteria. Pet owners are encouraged to keep their pets from urinating near public water sources, and the use of gloves is recommended when cleaning urine accidents.
