Leptospirosis is a bacterial infection affecting humans and animals. It is typically spread through direct contact with an infected animal, or more commonly by exposure to water sources contaminated by the urine of an infected animal. Dogs, even those kept primarily indoors, are especially at risk because of their increased exposure to potentially contaminated water (i.e. lakes, puddles, dew, etc.), soil and wildlife (i.e. raccoons, squirrels, opossums, etc.).  Responsible pet ownership, including vaccination, helps pet owners protect their pets from this devastating disease.  


RECOMBITEK C8 and RECOMBITEK 4 Lepto are the only vaccines that:

  • prevent leptospirosis caused by Leptospira canicola, L. grippotyphosa, and L. icterohaemorrhagiae and aids in the prevention of L. pomona*; and
  • prevent dogs from shedding bacteria into the environment after exposure*; and
  • provide more than 15-month duration of immunity**.


Merial has a 20-year history of offering advanced recombinant vaccine technology to help protect dogs from canine distemper and Lyme disease.

RECOMBITEK C8 is recommended for the vaccination of healthy dogs nine weeks and older for protection from the four common leptospirosis serovars and several of the core canine diseases.
