What is Nobivac L4?
Nobivac L4 is a vaccine available as a suspension for injection. It contains four inactivated (killed) strains of Leptospira bacteria.1.
What is Nobivac L4 used for?
Nobivac L4 is used to vaccinate dogs from six weeks of age to reduce the risk of developing an infection with certain Leptospira strains. Leptospirosis disease in dogs results in bleeding, hepatitis (infection of the liver) and jaundice (yellowing of the skin and eyes) or nephritis (kidney infection). The main infection source is from urine or
The vaccine is given to dogs as two injections, four weeks apart, under the skin. The first injection can be given from six to nine weeks of age and the second four weeks later. When puppies are known to have high levels of maternally derived antibodies (special type of proteins, received from the mother in the milk, that help the body to fight infection), it is recommended that the first vaccination is given at

nine weeks of age. A single ‘booster’ injection should be given every year to maintain the vaccine’s effect.
How does Nobivac L4 work?
Nobivac L4 is a vaccine. Vaccines work by ‘teaching’ the immune system (the body’s natural defences) how to defend itself against a disease. When Nobivac L4 is given to dogs, the immune system recognises the bacteria contained in the vaccine as ‘foreign’ and makes defences against them. In future if the animals are exposed to the bacteria the immune system will be able to respond more quickly. This will help to protect against the disease.
How has Nobivac L4 been studied?
The company has presented data from both laboratory and field studies to establish the safety and effectiveness of the vaccine, including how long it took for the dogs to be fully protected and how long the vaccine could provide protection.
What benefit has Nobivac L4 shown during the studies?
The studies showed that the vaccine reduces infection with Leptospira and excretion of the bacteria into the urine. They also showed that the vaccine is safe to give to pregnant bitches.
What is the risk associated with Nobivac L4?
A mild and temporary increase in body temperature ( 1°C) may occur for a few days after vaccination, with some puppies showing less activity and/or a reduced appetite. A small, temporary swelling may occur at the injection site, which will either disappear or reduce in size within two weeks after vaccination. An occasional temporary, acute
Why has Nobivac L4 been approved?
