Nobivac Lepto 4 Vaccine (L4)

You may have heard of a new vaccine on the market, the Nobivac Lepto 4 vaccine produced by MSD Animal Health, we have put together this information sheet to help you understand what it all means.

What is leptospirosis?

Leptospirosis is a bacterial disease that can lead to severe liver and kidney disease in dogs. It is spread via the urine of infected dogs, in addition to other mammals like rats and mice. The bacteria
enters the body via mucous membranes, broken skin and the ingestion of infected material. The disease is a zoonosis which means it can be spread from animals to humans or humans to animals, in humans the disease is known as Weil’s disease. There are a number of different types of Leptospira.

What is in our standard lepto vaccine?

The vaccination we use vaccinates against the two most common serogroups (types) of lepto:

  • Leptospira canicola
  • Leptospira icterohaemorrhagiae

What is in Lepto 4?

The new lepto 4 vaccine contains the same two serogroups as our current vaccine but also provides some protection for two other serogroups: Australis and Grippotyphosa.

Our position

Currently we have decided to not start routinely using the new vaccination for the following reasons;

  • There is limited evidence to suggest the 2 new serogroups in the new vaccine are of significant prevalence in the UK.
  • The time for the primary vaccination course is longer. This means puppies are missing out on essential socialisation time.

If you have any queries or questions in regard to the new vaccine or our vaccine protocol then please do contact us. If you request the new vaccine we will happily vaccinate your dog with it but you will have to give us some notice to order it in for you.

We endeavour to keep up to date with any new evidence as is it appears and will adapt our vaccination protocol as necessary in the future.
