4 CLINICAL PARTICULARS

4.1 Therapeutic Indications

For prophylaxis in circumstances where exposure to Bacillus anthracis may be expected or anticipated.

4.2 Posology and Method of Administration

Primary Immunisation: Four doses each 0.5 mL.

The first three doses should be administered at intervals of three weeks. The fourth dose should follow some six months after the third.

Booster injection: One dose of 0.5 mL administered annually.

Paediatric population

The safety and efficacy of Anthrax Vaccine in children has not been established. No data are available.

There is no evidence on which to recommend a different dose or doses for children or the elderly, although the vaccine will rarely be administered to these groups.

In cases where one or more of the recommended doses has been missed, it is recommended that expert advice is sought and/or official guidance is consulted regarding the appropriate dose regimen that should be followed in order to provide protection.

Method of Administration:

Anthrax Vaccine should be administered by intramuscular injection, preferably into the deltoid muscle.

4.3 Contraindications

  • Previous hypersensitivity reaction to an Anthrax Vaccine.
  • Known hypersensitivity to any of the ingredients in Anthrax Vaccine listed in

    Section 6.1.

  • Vaccination should be postponed in subjects suffering from acute severe febrile illness unless it is considered urgent to protect the individual. The presence of a minor infection is not a contra-indication for vaccination.

4.4 Special Warnings and Precautions for Use

As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of a rare anaphylactic event following administration of the vaccine.

Anthrax Vaccine contains thiomersal as a preservative, which may elicit hypersensitivity reactions. Anthrax Vaccine must not be administered to subjects who are known to be hypersensitive to thiomersal (see sections 4.3 and 6.1).

In subjects with an impaired immune system, an adequate immune response may not be obtained. If possible, vaccination should be delayed until the completion of any immunosuppressive treatment. Subjects with chronic immunodeficiency may be vaccinated but the immune response may be impaired.

As with any vaccine, a protective immune response may not be elicited in all vaccinees.

4.5 Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed.

Anthrax Vaccine must not be mixed with any other vaccine or other medicinal product in the same syringe. If necessary, Anthrax Vaccine may be given at the same time as other vaccines. Other injectable vaccines should be administered by separate injections into different anatomical sites and, ideally, into different limbs. Subjects who are receiving immunosuppressive therapy, including high dose corticosteroids, may be given Anthrax Vaccine but may not mount an adequate immune response.

4.6 Fertility, Pregnancy and Lactation

Pregnancy

Anthrax Vaccine should not be given to pregnant women unless the possible benefits of vaccination are considered to outweigh any potential risks to the foetus.

Breast-feeding

There is no information on administration of Anthrax Vaccine to breast-feeding women.

Vaccination should be avoided unless it is considered essential.

Fertility

No studies have been conducted on the effect of the Anthrax Vaccine on fertility.
