It has been just over a year since Lepto 4-Way™ was introduced to the market. To recap, a nationwide survey of dairy farms revealed a new strain of leptospirosis present on many farms across New Zealand. In response, Lepto 4-Way™ was developed and launched.
The uptake from Vetlife clients has been excellent, with many making the switch by taking advantage of our discounted second booster offer. You are to be congratulated for prioritising the health of both your herd and the people who work with them.
Leptospirosis is one of the most significant health risks for people working in the dairy industry. The effects of lepto can be very serious, with severe ftulike symptoms that often last for many months. We have been very fortunate to have highly effective cattle vaccines since the 1970s, which have reduced the devastating impacts on farmers, their families and livelihoods.

A common question we hear is: Why do we vaccinate if we rarely see the disease? The answer lies in the effectiveness of the vaccine. When vaccination works well – as it does with Lepto vaccines – disease becomes rare. But that does not mean the threat is gone.
It is crucial not to become complacent. Vaccinations must be administered on time, and vaccines must be stored and handled correctly to maintain their effectiveness. The goal of any leptospirosis vaccination programme is to prevent infection altogether.
Leptospira bacteria colonise the kidneys of infected cattle and are shed in their urine. Given how frequently cows urinate in the shed, the risk to those working with them is significant. The bacteria can enter the body through cuts, abrasions, or mucous membranes such as the eyes and mouth.
Remember: vaccination is a preventative measure, not a cure.
Once an animal is infected, vaccination will not eliminate the infection though it may reduce bacterial shedding in some cases. That is why it is essential to vaccinate calves early and maintain protection with annual boosters.
Please check your records to ensure your leptospirosis vaccination programme is up to date. Do not let protection lapse – waning immunity can leave both livestock and staff vulnerable. And, of course, the vaccine only works if administered and not left forgotten in the fridge!
If you have any queries around leptospirosis vaccination – or any other vaccine – please contact your local Vetlife veterinarian. We are here to help.
