SILIRUM® is an inactivated vaccine for the immunization of Mycobacterium avium ssp. paratuberculosis in cattle
Silirum dose

A tool for prevention

SILIRUM is an essential tool for the control of Paratuberculosis in cattle.

Just one dose

One dose of SILIRUM produces a longlasting cellular response and immunological memory for lifetime, contributing to the control of Bovine Paratuberculosis.


Flexible Vaccination program for all stages of life

Vaccination with SILIRUM can be performed on young animals (under one year of age), or in adult animals. If the prevalence of the disease in the herd is high, it is recommended to vaccinate the whole herd.

Decreases the prevalence of Paratuberculosis

SILIRUM is an essential tool in the control of Bovine Paratuberculosis in herds. Vaccination with SILIRUM reduces the faecal shedding of M. a. paratuberculosis, thus reducing contamination in the environment and disease transmission.


Decreases intestinal lesions

SILIRUM reduces intestinal bacterial load, decreasing the number and severity of lesions caused by M. a. paratuberculosis and the subsequent morbidity-mortality rates.

Increases productivity

The benefits of vaccination take into account not only the reduction of mortality and level of infection in the flock, but also the prevention of future losses in production yields.


Benefits after SILIRUM vaccination

  • Control of the appearance of clinical cases of Paratuberculosis.
  • Improves milk production.
  • Cost-benefit of one dose for lifetime protection of animals.
  • Increases longevity and reduces replenishment rate.
  • Reduction on number of culled animals.

Widely tested

Different studies of SILIRUM have shown to be a valuable method to reduce clinical signs and has a general positive effect in production.
