4 Clinical Particulars

4.1 Therapeutic Indications

Q-Vax Vaccine is indicated for the immunisation of susceptible adults at identifiable risk of infection with Q fever.
Abattoir workers (and those closely associated with the meat industry), farmers, veterinarians, stockyard workers, shearers, animal transporters and many others exposed to cattle, sheep or goats or their products should be considered for vaccination.
Note also that Q fever has occurred among persons culling and processing kangaroos and that laboratory personnel handling potentially infected veterinary specimens, or visiting abattoirs, are at risk.
Q-Vax Skin Test is indicated for the prescreening of potential vaccine recipients for prior sensitisation to Q fever antigens.
It is essential to test for sensitisation to Q fever antigens using Q-Vax Skin Test in every individual prior to immunisation (see Section 4.4 Special Warnings and Precautions for Use).

4.2 Dose and Method of Administration

Q-Vax Vaccine.

Q-Vax Vaccine should not be administered until the results of serology and skin testing are known (see Section 4.4 Special Warnings and Precautions for Use). Q-Vax should be given only to those who have no demonstrable evidence of sensitisation to Q fever antigens.
The dose of Q-Vax Vaccine is 0.5 mL given by subcutaneous (not intramuscular) injection. The container should be gently shaken before use.
The vaccine should never be administered intravenously.
No information is available on paediatric use.
Revaccination must never be undertaken due to the possibility of severe hypersensitivity reactions.

Q-Vax Skin Test.

Preparation.

Skin Test solution should be prepared by diluting 0.5 mL of the Q-Vax Skin Test in 14.5 mL of sodium chloride injection (to a final volume of 15 mL). The diluted Q-Vax Skin Test should be freshly prepared, stored at 4°C and used within six hours.

Administration.

The dose administered for skin testing is 0.1 mL of the diluted Q-Vax Skin Test. This should be injected intradermally into the volar surface of the mid-forearm.

4.3 Contraindications

Q-Vax should not be administered to:
Persons who have a history of Q fever.
Persons who have been previously vaccinated with Q fever vaccine.
Persons who have a history of likely exposure followed by an illness strongly suggestive of Q fever.
Persons with positive serology for Q fever antibody or a positive Q fever skin test.
Persons with known hypersensitivity to egg proteins or any component of the medicinal product.

4.4 Special Warnings and Precautions for Use

Prior to immunisation, all potential vaccinees must have a serum antibody estimation and a skin test reported; administration of Q-Vax to those who are already sensitised to Q fever antigens can cause serious hypersensitivity reactions.
As with other injectable vaccines, including Q-Vax Skin Test solution, appropriate medical treatment and supervision should always be available in case of anaphylactic reactions. Adrenaline should always be readily available whenever the injection is given.
Q-Vax should never be administered intravenously.
There is no information available on the efficacy and safety of Q-Vax in immunodeficient or immunosuppressed individuals.
Those who have a confirmed positive antibody test or a positive skin reaction must not be given Q-Vax (see Prevaccination testing).
If the skin test is negative or equivocal and antibodies are present at low titres (reported as a borderline laboratory test result), it cannot be concluded that the subject has adequate protective immunity against Q fever. The low level presence of antibodies may be nonspecific or due to technical factors of the assay. The risk/ benefit decision of being vaccinated or not should be individually assessed and discussed with the subject, in order to decide whether potential adverse events following vaccination outweigh the potential risk to that subject from Q fever infection and its associated complications.
It should be noted that a very small number of people may have had Q fever in the past and yet show no response to serological or skin testing. Such persons may have severe reactions to Q-Vax. For this reason, subjects should be carefully questioned regarding the possibility of previous exposure to Q fever and the duration of such exposure.
Workers who are at risk of contracting Q fever should be immunised prior to commencement of work or as soon as possible after they commence work as the risk of infection is highest in the first few years.
Vaccination during the incubation period of Q fever does not prevent the onset of the disease.
Despite the significant efficacy of Q-Vax in clinical trials, cases of Q fever following vaccination have been reported (see Section 5.1 Pharmacodynamic Properties, Clinical trials).

Prevaccination testing.

Serology. People who are being considered for Q fever vaccination must have serum antibody testing. Subjects in whom antibodies are unequivocally positive should not be given Q-Vax (see Section 4.4 Special Warnings and Precautions for Use).
Skin test.

Preparation.

Skin Test solution should be prepared by diluting 0.5 mL of the Q-Vax Skin Test in 14.5 mL of sodium chloride injection (to a final volume of 15 mL). The diluted Q-Vax Skin Test should be freshly prepared, stored at 4°C and used within six hours.

Administration.

The dose administered for skin testing is 0.1 mL of the diluted Q-Vax Skin Test. This should be injected intradermally into the volar surface of the mid-forearm.
A positive reaction is indicated by any induration at the site of injection read seven days after the test dose. Any person with a positive reaction must not be vaccinated.

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Q fever is caused by Coxiella burnetii, an obligate, intracellular, Gram-negative coccobacillus. The C. burnetii is shed in the products of conception, and on the neonate of the infected animal. It may also be present in the udder and milk of infected animals and is passed on within their faeces and urine. Infection is transmitted to humans primarily by inhalation of infected airborne particles or dust during the handling or processing of these materials or by close proximity to infected animals and their products.
Administration of inactivated Coxiella burnetii in Q-Vax vaccine stimulates production of an immune response in the vaccinated individual. The immune response provides protection against clinical illness in a high proportion of vaccinated individuals, but may not be effective in some individuals.
Early antibody response to the vaccine is predominantly with the IgM subclass; IgG antibodies appear later. Although the seroconversion rate is low (50-80%) and antibody levels are transient, cell mediated immunity develops. Clinical trials have demonstrated a high degree of efficacy (see Section 5.1 Pharmacodynamic Properties, Clinical trials). As Q fever is often asymptomatic or misdiagnosed due to its non-specific nature, many abattoir workers develop immunity to Q fever without an obvious illness.
The duration of protective immunity following immunisation is unknown, but is believed to be in excess of five years.
Revaccination must never be undertaken due to the possibility of severe hypersensitivity reactions (see Section 4.3 Contraindications).

Clinical trials.

A randomised, blind, controlled study comparing Q-Vax and influenza vaccine for the prevention of Q fever amongst 200 workers in three Queensland abattoirs was undertaken, using sequential analysis for determining the efficacy of Q-Vax. A statistically significant difference in the incidence of symptomatic Q fever was noted 15 months after commencement of vaccination, with 7 cases in those given the control vaccine and no cases in those given Q-Vax. At 15 months, 24% of those who had not been vaccinated and had not developed symptomatic infection had serological evidence of exposure to Q fever, indicating subclinical infection.
A retrospective cohort study in three South Australian abattoirs was undertaken to compare the incidence of Q fever in vaccinated and unvaccinated subjects between 1985 and 1990. There were two cases of Q fever amongst 2555 vaccinated employees compared with 55 cases in 1365 unvaccinated subjects. Both cases of Q fever in the vaccinated group occurred within two weeks of receiving the vaccine. For workers who were vaccinated, the mean duration of employment following vaccination was 1.9 years; 203 workers were employed for all five years of the study. Protection against clinical infection over this period was demonstrated.
Although the dose in each of these studies was nominally 30 microgram, one batch which contained only 20 microgram in each dose was shown to be as effective. However, as with all vaccines, 100% effectiveness for generation of protective immunity against Q fever cannot be guaranteed (see Section 4.4 Special Warnings and Precautions for Use).
