Lepto 4-Way® is an inactivated leptospirosis vaccine developed in response to the emergence of the Tarassovi-like serovar, ‘Pacifica’. As well as Tarassovi, the vaccine also contains serovars Hardjo, Copenhageni and Pomona - serovars that have been identified to cause disease in livestock and humans in New Zealand.
Recent epidemiological studies1,2 suggest Pacifica’s prevalence is high in dairy herds in New Zealand, leading to a disproportionate disease incidence and emotional toll on dairy farmers and their families.
