Brucella abortus vaccine

Brucellosis is a controlled disease in terms of the Animal Disease Act, (Act 35 /1984). Any occurrence or suspected occurrence of brucellosis must be reported immediately to the local state veterinarian.

This vaccine may only be used by or under the supervision of persons registered in terms of, or authorised in terms of, Section 23 (1) (c) of the Veterinary and Para- Veterinary Professions Act, 1982 (Act 19 of 1982).

INDICATIONS

For use in healthy female cattle as an aid in the prevention of infection and abortion caused by Brucella abortus.

COMPOSITION

This lyophilised vaccine contains the RB-51 strain of Brucella abortus.

STORAGE

  • Store between 2 °C and 8 °C.
  • Protect from light.

WARNINGS

  • DO NOT VACCINATE PREGNANT ANIMALS.
  • Withdrawal period:

Meat – do not slaughter for human consumption within 21 days of administration.

Milk – if adult cows are vaccinated, milk should be pasteurized or boiled before use for human consumption. Consult the state veterinarian if you are intending to vaccinate adult cattle.

  • If an anaphylactic reaction occurs administer adrenaline or an equivalent.
  • In the case of accidental human exposure contact your physician.
  • KEEP OUT OF REACH OF CHILDREN, UNINFORMED PERSONS AND ANIMALS.
  • Although this vaccine has been extensively tested under a large variety of conditions, failure thereof may ensue as a result of a wide range of reasons. If this is suspected, seek veterinary advice and notify the registration holder.

Warning to Medical Practitioners

This organism is rifampicin resistant. Alternative antibiotic therapy will therefore be essential should a patient be infected.

An immunologic response to the RB-51 strain is not detected on routinely available serological tests used for the diagnosis of Brucella abortus infections.

A reasonable interim course of post-exposure prophylaxis for adults would be doxycycline 100 mg orally twice daily for 21 days, with the addition of other suitable antimicrobials if evidence of infection appears.

PRECAUTIONS

  • Do not eat, drink or smoke during administration of RB-51.
  • Wash and disinfect hands after vaccination.
  • Care should be taken to avoid direct contact and self-injection.
  • Use entire contents when first rehydrated.
  • Dispose of any unused vaccine as well as all vaccine containers and vaccination equipment according to local waste disposal regulations.

PREGNANCY AND LACTATION

Do not vaccinate pregnant cattle due to the risk of abortion and potential shedding of the RB-51 strain in calving fluids and milk.

For further information, please consult your veterinarian or MSD Animal Health’s technical advisors.
