Can cattle be vaccinated against bovine TB?
Over the last 20 years, APHA and our collaborators have demonstrated that BCG (referred to as CattleBCG when used to vaccinate cattle), can also protect cattle against bovine TB in experimental studies.
How do you prevent bovine TB in cattle?
Current control measures include routine skin testing of herds at regular intervals, additional and more targeted testing of TB-infected and at-risk herds, TB surveillance of cattle at slaughter, movement restrictions of infected herds, the use of pre- and post- movement testing, good biosecurity and animal husbandry.
Why don’t we vaccinate for TB in cattle?
TB vaccines have been developed for cattle, but these can cause false positives in TB skin tests making it difficult to detect infected animals. It is not possible to vaccinate cattle in the field under EU legislation so research is done using experimentally infected cattle1.
What is in a 5-way vaccine for cattle?
The pre-breeding vaccines are basically a 5-way with campylobacter bacterin (used to be called vibrio) and leptospirosis antigens added. These additions are to help prevent fetal loss/abortions or failure to conceive.

How many times a year do you vaccinate cattle?
The infectious vaccine may give properly vaccinated cattle immunity for life. Repeated modified live infectious vaccinations are unnecessary. However, immunity of the vaccinated animal can be ensured by using a non infectious vaccine booster every year or an infectious vaccine every 3 years.
How serious is bovine TB?
Bovine TB usually affects animals such as cattle, but it can affect practically all mammals causing a general state of illness, coughing and eventual death.
