Gudair®
Description
- Gudair® is Australia's only vaccine for the control of ovine Johne’s disease (OJD).
- It contains inactivated (killed) Mycobacterium paratuberculosis strain 316F and when combined with the adjuvant offers protection against the development of clinical OJD and a reduction in faecal shedding of the organism in sheep.
Key Benefits
- Significant decrease in the number of clinically affected animals over time
- Decrease in the number of mortalities associated with OJD
- Gradual decrease in the prevalence of infection within the flock
- Notable decrease in faecal M.paratuberculosis shedding.
Recommendations for Use
- Active immunisation for the control of ovine Johne's disease and reduction of faecal Mycobacterium paratuberculosis shedding in sheep.
- Active immunisation as an aid in the control of Johne's disease in goats.
-
It’s strongly recommended to use the Gudair Sekurus® 1mL Safety vaccinator when administering Gudair and use a 6mm, ¼ inch needle.
- Its safety features reduce the risk of accidental self-injection.

Applicator Recommendations
- Clean and maintain the vaccinator as outlined by the manufacturer daily.
- DO NOT use disinfectants at the site of vaccination or to clean the vaccinator or needle.
- Ensure the needle is sharp and not burred, replace often.
- This product must be injected ONLY under the skin
- Further vaccine (booster) doses are not required.
Pack Size
Plastic packs: 100 mL, 250 mL.
Storage
- After vaccination a firm swelling usually develops at the site of injection. 2 months after vaccination most swellings will have decreased in size, and they usually continue to decrease over time. It is not unusual for an injection site nodule to appear 7-15 days after vaccination, which in a small proportion of animals may become larger than 5 cm in diameter, however the majority if site reactions will be less than 2 cm diameter when the recommended vaccination technique is followed. When this vaccine is administered to animals already infected with or sensitised to M. paratuberculosis, a more intense focal reaction (secondary immune response) can occur.
- In a small proportion (5%) of animals the swelling may develop into an abscess and burst. This may attract flies. Accordingly, vaccinated animals should be checked regularly for fly strike and be treated where necessary. Alternatively, preventative fly strike treatments should be given. Vaccinated animals, if sent for slaughter soon after vaccination, may be subject to additional trimming due to vaccination injection site reactions.
Ensure that the vaccine does not enter your body through contact with the needle (self-injection, needle scratch, etc) or entry through an open wound. Be especially careful that it doesn't enter your body through contact with eyes, mouth and skin, because the vaccine is an irritant. Wash your hands thoroughly with soap and water after use, especially if the vaccine comes into contact with your skin.
GUDAIR Vaccine contains mineral oil. Even when a small amount is accidentally injected into a human, intense swelling and a persistent granulomatous inflammatory reaction can occur. If injected into a finger joint or tendon sheath, the product may track along the tendon. The swelling and inflammation post injection may compromise blood supply and result in necrosis. In rare cases this can lead to the loss of a digit. Given the potential for serious side effects, all persons should seek prompt medical attention. Every case is different and the correct medical advice is a matter for the treating physician.
1. In the case of superficial skin exposure, eye exposure and oral ingestion:
• Skin contact: wash the contaminated area with warm soapy water.
• Eye splash: remove contact lens if worn and rinse eyes thoroughly with cool water from a running tap or a cup/jug and continue to flush for at least 15 minutes.
• Oral ingestion: rinse mouth with cool water.
2. In the case of needle-stick injuries without known injection of vaccine:
• Allow the wound to bleed freely and do not squeeze or otherwise interfere with the wound or injection site. Then wash the wound thoroughly with warm water and keep clean and dry.
3. In the case of actual injection of vaccine:
• Acute pain and inflammation are usually still evident 24 hours after the suspected injection occurred.
• In cases of self-injection, surgical attention is required.
Contact a doctor as soon as possible, even if only a very small amount is injected, and take this package leaflet/carton with you.
Information for healthcare professionals about human accidental self-injection and exposure to Gudair® vaccine
What is Gudair vaccine used for?
Gudair vaccine is used in sheep and goats to protect them from a wasting disease known as Johne’s disease. Johne’s disease is caused by Mycobacterium paratuberculosis.
What is contained in Gudair vaccine?
Each dose of Gudair vaccine contains:
- Inactivated Mycobacterium paratuberculosis organisms
- Mineral Oil
- Thiomersal (preservative)
The oil typically forms a depot at the injection site to act as a potent adjuvant in stimulating a cell-mediated immune response to the mycobacteria. The action of the adjuvant and antigen combination in this vaccine produces a reaction similar to that elicited by Freund’s complete adjuvant.
Accidental self-injection
Gudair vaccine contains mineral oil and inactivated mycobacterium paratuberculosis (Freund’s-like). Even when a small amount of the vaccine is accidentally injected into a human, intense swelling and a persistent granulomatous inflammatory reaction can occur. If injected into a finger joint or tendon sheath, the product may track along the tendon. The swelling and inflammation post injection may compromise blood supply and result in necrosis. In rare cases this can lead to the loss of a digit. Given the potential for serious side effects, all persons should seek prompt medical attention. Every case is different, and the correct medical advice is a matter for the treating physician.
Some common strategies recommended by healthcare professionals
We are aware of the following treatment strategies being frequently recommended by physicians in the past:
- Superficial skin exposure, eye exposure and oral ingestion:
-
Skin contact: wash the contaminated area with warm soapy water
- Eye splash: remove contact lens, and rinse eyes thoroughly with cool water from a running tap or a cup/jug and continue to flush for at least 15 minutes
- Oral ingestion: rinse the mouth out with cool water
- Needle-stick injuries without known injection of vaccine:
-
Doctors have recommended that the wound be allowed to bleed freely and that the wound orinjection site not be squeezed or otherwise interfered with. Doctors have recommended that the wound then be cleaned thoroughly with warm water and then kept clean and dry
- Doctors have also considered that, following appropriate immediate local cleansing, corticosteroids may decrease the severity of any local reaction
- Doctors have frequently determined the patient’s tetanus immunisation status and administered a booster or primary series, as appropriate
- Commonly, if there is no pain or swelling 24 hours post exposure, doctors have continued to monitor for at least a month and treat any clinical symptoms accordingly
- Actual injection of Gudair vaccine:
- Doctors have observed that acute pain and inflammation is usually still evident 24 hours after the suspected injection occurred
- In cases of self-injection, doctors have considered that prompt surgical attention has been required
and, in those case, the doctors have: - incised the wound to remove the vaccine, especially where there is involvement of finger pulp or tendon
- in the case of a lesion that has progressed to necrosis or granulomatous ulceration,
physicians have performed surgical debridement to remove residual vaccine material - Doctors have stated that meticulous technique has been required to stop inadvertent spread
of the product during surgery
Given the nature of this Freund’s-like vaccine, Zoetis recommends that any healthcare professional
speak with a surgeon who has experience with the treatment of cases of accidental self-injection
of Gudair to ensure the appropriate treatment is advised.
