Lepto incidence is at least 8%, based on research reported in the Journal of the AVMA. 33,000+ dogs were tested from all over the US.1 And regardless of the area — metro, suburban or rural — transmission can occur when a dog spends just a few minutes outside.

Plus, the number of potential carriers and places where infection can occur is in the billions.

That's a big risk. But there's an easy solution. It's Duramune® Max 5/4L with SubUnit4 Purification™ designed for added safety and a smooth injection.

Subunit4 Purification™ for a Smooth Injection

We treat the immunogens we use with an industry-exclusive, four-part purification process that removes cellular debris for a smooth injection.

Four steps to purified immunogens:

Proven Safe Inside the Lab and Out

We demonstrated Duramune® Max 5/4L's safety in the largest real-world safety study ever conducted on canine vaccines.2 During the study:

  • Duramune® Max 5/4L showed a low incidence of vaccine-associated adverse events (VAAEs) 
  • Nearly 30,000 doses of Duramune® Max 5/4L were administered to dogs in the real-world clinical settings
  • Fewer than three VAAEs appeared per 1,000 dogs vaccinated with Duramune® Max 5/4L

Get Efficacy You Can Trust

Duramune® Max 5/4L protects against all four serovars responsible for lepto infection in the United States. This includes today's most common lepto causes, grippotyphosa and pomona.

Plus, Duramune® Max 5/4L offers a proven track record, with more than 128 million lepto vaccine doses sold since 1986 -- more than any other manufacturer.3
