First unadjuvanted rabies vaccine for cats

Merial has just launched on the European market, the first and only vaccine against rabies for cats, without adjuvant. This vaccine was specially designed to meet the expectations of veterinarians concerned about the safety of vaccines, while ensuring rapid and effective protection against rabies, a disease that continues to pose a risk in Europe.

All rabies vaccines available to date that can be applied to cats are inactivated and adjuvanted in order to induce higher levels of immunity. However, several experts now agree that the use of unadjuvanted vaccines in cats is preferable, inducing a strong and complete immune response.

According to Pedro Fabrica, a veterinarian, “some studies question the safety of using adjuvants in cat vaccines, given that they cause a strong and persistent inflammatory reaction at the injection site, and where tumors can subsequently develop, for this reason it makes sense use vaccines without adjuvants that minimize the risk of inflammation”.

The formula of this new vaccine is an exclusive innovation from Merial, which uses the latest technology in vaccines, producing a strong and lasting immune response, without the need for an adjuvant, thus limiting the occurrence of inflammation at the injection site. The efficacy and safety of the new feline rabies vaccine has been proven in several studies carried out, covering more than 1.000 cats of different ages and breeds.

Although rabies has been eradicated from several European countries, several occurrences of the disease are still recorded, regularly diagnosed in bats infected with a specific virus [Lyssavirus (EBLV)], which is transmissible to domestic carnivores. Rabies vaccination remains the best way to protect cats from this disease.

The new unadjuvanted feline rabies vaccine allows for effective and safe vaccination, and is complementary to Merial's only full range of unadjuvanted feline vaccines.

What is Anger?

Rabies is a disease, currently extinct in Portugal, due to mandatory vaccination in dogs, instituted in the country and the active role of the Veterinarian in the eradication of the disease.

However, it is worth remembering that the ease of cross-border circulation can allow the entry of infected animals from countries at higher risk.

It is an infectious disease, caused by a virus, Lyssavirus genus, which installs and multiplies, initially, in the peripheral nerves and then in the central nervous system and salivary glands, where it spreads.

Pets (dogs and cats) are the main sources of transmission of rabies to humans. However, other mammals such as cattle, pigs, horses or wild animals such as rats and bats, for example, are potential transmitters if they have been infected through biting or licking the injured mucosa or skin by another rabid animal.

At first, symptoms are non-specific, such as fever, headache, malaise, anorexia, nausea and sore throat. There are also changes in sensitivity at the bite site, with tingling, numbness, itching or pain.

Then, neurological signs and symptoms set in, such as anxiety, disorientation, hallucinations, seizures triggered by tactile, auditory or visual stimuli, and death.
