Continual vaccination is a key component in achieving an effective, permanent reduction in Salmonella infection pressure throughout the herd.
For an effective reduction in Salmonella pressure, both sows and piglets should ideally be vaccinated. In sows, vaccination prevents or significantly reduces the shedding of wild strains of Salmonella Typhimurium during lactation, leading to a lower risk of infection for the piglets.
The aim of vaccination in piglets is to reduce the colonization and shedding of the pathogen in order to prevent animal-to-animal infection.
Any clinical symptoms present are suppressed.
For a lasting reduction in Salmonella infection pressure and a permanent improvement in farm category, continual vaccination is required until only vaccinated animals remain in the herd.
After this, continuing sow vaccination is recommended. Vaccination should be accompanied by appropriate hygiene measures (cleaning and disinfection, rodent and pest control, monitoring of farm procedures and working routes). Repeated testing of the herd (feces swabs, environmental samples, swipe samples) should accompany vaccination to help ensure long-term success.

Vaccination schedule with a live-attenuated Salmonella Typhimurium vaccine 

Immunity develops within 2 weeks of completing the vaccination course.

Duration of immunity:

In sows 24 weeks
In fatteners 19 weeks

Antibiotic use should be discontinued for five days before and five days after vaccination.
If such treatment is essential, the animals should be vaccinated five days later at the earliest.
