Vaccinate to protect cattle health and profits

Vaccines can prevent a wide range of diseases that cause reduced production, fertility or death in cattle and economic losses to Western Australian producers.

What diseases do cattle vaccines prevent?

Vaccines can prevent a wide range of diseases that cause reduced production, fertility or death in cattle and economic losses to Western Australian producers.

Vaccines can protect cattle against clostridial, reproductive and respiratory diseases as well as calf scours, bovine ephemeral fever and pinkeye.

Always follow the vaccine label directions to ensure the vaccination program is effective and to prevent residues in slaughtered animals.

Discussing your vaccination program with your private or government veterinarian will assist you to decide which vaccinations will be most valuable in maintaining your herd’s health and profitability.

Clostridial disease vaccines

Clostridial diseases, caused by bacteria in the Clostridium genus, cause serious livestock losses in Australia. These bacteria are normally present in the stomach, intestinal tract and muscles of cattle, and can live up to several years in soil, water or decomposing plant and animal material.

To cause disease, the clostridial bacteria need an opportunity to multiply such as when bruised muscle and tissue, cuts, abrasions or consumption of the bacteria occurs. The bacteria then release toxins that cause visible disease signs in the cattle.

The clostridial diseases of most importance in WA are blackleg, malignant oedema, enterotoxaemia, botulism and tetanus (see Table 1). Black disease is also included in some vaccines but is associated with liver fluke, which is not present in WA.

All cattle are at risk of clostridial diseases, however young stock are more commonly affected as the bacteria can gain access during marking, branding, dehorning, injections of antibiotics and vaccines, and castration. Blackleg is usually seen in rapidly growing animals from six months onwards or in cattle that have been bruised by poor transport, yarding and husbandry techniques.

(pulpy kidney)

Botulism usually occurs after cattle have ingested feed or water that has been in contact with decaying vegetable or animal matter. It is commonly seen in the extensive pastoral areas in the dry season where cattle chew on bones or decaying carcasses.

Reproductive and infertility disease vaccines

There are commercial vaccines available to prevent vibriosis, bovine pestivirus (BVD) and leptospirosis, diseases which affect fertility in cattle.


Vibriosis is a venereal disease of cattle caused by the bacteria Campylobacter fetus ssp. venerealis that lives in the prepuce of infected bulls. It only takes a single service to infect cows and heifers that have not been in contact with the disease before.

The disease usually goes unnoticed until the producer sees abnormally high numbers of heifers and cows return to the bull at irregular intervals, abnormally high numbers of empty cattle at pregnancy testing, or abortions.

Bovine pestivirus

Bovine viral diarrhoea (BVD) is a complex disease caused by bovine pestivirus type 1. See the bovine virus diarrhoea page for more information.

It is important to understand the disease and to contact your local veterinarian for advice before vaccinating your herd for BVD.


In Australia leptospirosis is caused by Leptospira interrogans serovars pomona and hardjo, and Leptospira borgpetersenii serovar hardjo. It causes significant illness and abortion in cattle herds.

The main signs in cattle are return to oestrus due to early embryonic loss, dullness, lethargy and fever. It can also infect the reproductive tract of cows and heifers.

The disease is highly contagious and infected animals shed high levels of leptospires in urine. Cattle and humans contract leptospirosis from contact with body fluids of infected animals including cattle, pigs, rats and mice. It is important to vaccinate for leptospirosis in cattle as the disease in people can cause meningitis, kidney and liver failure if not treated early.

Respiratory disease vaccines

There are two vaccines available to prevent and control respiratory disease in cattle in Australia. The vaccines are generally used to prepare cattle going into feedlots and while in feedlots.

The two infectious agents covered by these vaccines are infectious bovine rhinotracheitis virus and Mannheimia haemolytica.

Infectious bovine rhinotracheitis virus (bovine herpes virus type 1)

Infectious bovine rhinotracheitis (IBR) is a respiratory disease caused by bovine herpes virus type 1. It often occurs in feedlot cattle, although it is sometimes seen in grazing cattle.

Signs include laboured breathing, coughing and discharges from the eyes and nose. There may also be signs of dullness and lethargy, along with fever. Younger cattle can die of pneumonia if infected with a secondary bacterial infection like Mannheimia haemolytica.

Mannheimia haemolytica

This bacterium often contributes to severe pneumonia in cattle that are infected with IBR or another respiratory virus.

Neonatal calf scours vaccines

If scours in calves is ongoing, contact your private veterinarian or Department of Primary Industries and Regional Development Field Veterinary Officer to investigate the cause of the scours so the appropriate treatment can be implemented. Vaccines are available for Escherichia coli, Salmonella typhimurium and Salmonella dublin if these bacteria are responsible for the outbreak. In most cases the cow needs to be vaccinated to boost antibodies in the colostrum to provide early protection against scours in calves.

Bovine ephemeral fever disease vaccine

Bovine ephemeral fever (BEF), known as ‘three-day sickness’, is caused by a virus spread by biting midges and mosquitoes. The disease is usually seen during autumn and spring when the midges and mosquitoes are most active. BEF only occurs where the midges and mosquitoes occur.

In WA the virus occurs in the northern Kimberley and occasionally southern Kimberley and parts of the Pilbara. Cattle of all ages can be affected, but BEF is most commonly seen in cattle between six months and about two years old.

Signs of BEF include an inability to rise or walk, stiffness, fever, dullness, lethargy and not eating. Cattle usually recover after three days.

Vaccination is only recommended for bulls introduced from areas outside the BEF area. For example, vaccinating bulls from southern WA will provide some protection if they come into contact with the virus once in the BEF disease area.

Pinkeye vaccine

Infectious bovine keratoconjunctivitis (IBK) or pinkeye is a common contagious eye disease usually seen in young cattle during dry periods.

Signs include streaming tears, cloudy eye(s), red and closed eyelids or increased blinking.

Currently there is only one vaccine in Australia to help prevent pinkeye in cattle. Cattle need to be vaccinated 3–6 weeks before the pinkeye season, and revaccinated every year to maintain immunity.

It is recommended that you obtain advice from a private veterinarian about pinkeye vaccination of your herd. If vaccination is used during an outbreak, results are variable.
