4. Clinical particulars
4.1 Therapeutic indications

Rabies Vaccine BP is indicated for pre- exposure prophylaxis and for post-exposure prophylaxis against rabies in all age groups (see Sections 4.2 and 5.1).

The use of Rabies Vaccine BP should be based on official recommendations.

4.2 Posology and method of administration

Posology

The recommended dose is 1mL of reconstituted vaccine.

Pre-exposure prophylaxis

The primary pre-exposure immunisation course consists of 3 injections at D0, D7 and either D21 or D28.

For individuals at continued risk, booster doses should be given in line with official recommendations.

The need for serology testing to detect the presence of rabies virus-neutralising antibodies (≥0.5 IU/ml) should be assessed and conducted, if appropriate, in accordance with official recommendations.

Post-exposure prophylaxis

Post-exposure prophylaxis should be initiated as soon as possible after suspectedrabies exposure. In all cases, proper wound care (thorough flushing and washing of all bite wounds and scratches with soap or detergent and copious amounts of water and/or virucidal agents) must be performed immediately or as soon as possible after exposure). It must be performed before administration of rabies vaccine or rabies immunoglobulin, when they are indicated.

The rabies vaccine administration must be performed strictly in accordance with the category of exposure, the patient immune status, and the animal status for rabies (according to local official recommendations, see Table 1 for WHO recommendations).

Table 1: WHO category of severity of exposure

Category of exposure

Type of exposure to a domestic or wild animal suspected or confirmed to be rabid or animal unavailable for testing

Recommended post-exposure prophylaxis

I

Touching or feeding of animals

Licks on intact skin

(no exposure)

None, if reliable case history is availablea

II

Nibbling of uncovered skin

Minor scratches or abrasions without bleeding

(exposure)

Administer vaccine immediately

Stop treatment if animal remains healthy throughout an observation period of 10 daysb or is proven to be negative for rabies by a reliable laboratory using appropriate diagnostic techniques.

Treat as category III if bat exposure involved.

III

Single or multiple transdermalc bites or scratches, contamination of mucous membrane or broken skin with saliva from animal licks, exposures due to direct contact with bats.

(severe exposure)

Administer rabies vaccine immediately, and rabies immunoglobulin, preferably as soon as possible after initiation of post-exposure prophylaxis.

Rabies immunoglobulin can be injected up to 7 days after administration of first vaccine dose.

Stop treatment if animal remains healthy throughout an observation period of 10 days or is proven to be negative for rabies by a reliable laboratory using appropriate diagnostic techniques.

a If an apparently healthy dog or cat in or from a low-risk area is placed under observation, treatment may be delayed.

b This observation period applies only to dogs and cats. Except for threatened or endangered species, other domestic and wild animals suspected of being rabid should be euthanized and their tissues examined for the presence of rabies antigen by appropriate laboratory techniques.

c Bites especially on the head, neck, face, hands and genitals are category III exposures because of the rich innervation of these areas.

Post-exposure prophylaxis of previously non-immunised individuals

Vaccine should be administered on D0, D3, D7, D14 and D28 (5 injections of 1mL).

For category III exposure (see Table 1), rabies immunoglobulin should be given in association with vaccine. In this case, the vaccine should be administered contra-laterally, if possible.

Vaccination should not be discontinued unless the animal is declared not rabid according to a veterinarian assessment (supervision of animal and/or laboratory analysis).

Post-exposure prophylaxis of previously immunised individuals

Previously immunised individuals should receive one dose of vaccine intramuscularly on both days 0 and 3. Rabies immunoglobulin is not indicated in such cases.

According to WHO recommendation, previously immunised individuals are patients who can document previous complete PrEP (pre-exposure prophylaxis) or PEP (post-exposure prophylaxis) and people who discontinued a PEP series after at least two doses of a cell culture rabies vaccine.

Special population- immunocompromised individuals

• Pre-exposure prophylaxis

For immunocompromised individuals, serology testing of neutralizing antibodies should be performed 2 to 4 weeks after the vaccination to assess the possible need for an additional dose of the vaccine.

• Post-exposure prophylaxis

For immunocompromised individuals, only a full vaccination schedule should be administered. Rabies immunoglobulin should be given in association with the vaccine for both categories II & III exposures (see Table 1).

Paediatric population

Paediatric individuals should receive the same dose as adults (1mL).

Method of Administration

The vaccine is for intramuscular administration only. The vaccine should be administered into the deltoid muscle for adults and children or the anterolateral area of the thigh muscle in infants and toddlers. For instructions on the reconstitution of the vaccine before administration, see section 6.6.

4.3 Contraindications

Pre Exposure

Known systemic hypersensitivity reaction to any component of Rabies Vaccine BP or after previous administration of the vaccine or a vaccine containing the same components as Rabies Vaccine BP.

Vaccination must be postponed in case of febrile and/or acute disease.

Post Exposure

Since declared rabies infection generally results in death, there are no contraindications to post exposure vaccination.

4.4 Special warnings and precautions for use

As with any vaccine, vaccination with Rabies Vaccine BP may not protect 100% of vaccinated individuals.

In subjects with a history of allergy there may be an increased risk of side-effects and this possibility should be taken into account.

As with all vaccines, appropriate facilities and medication such as epinephrine (adrenaline) should be readily available for immediate use in case of anaphylaxis or hypersensitivity following injectionThe vaccine may contain traces of neomycin and betapropiolactone which are used during the manufacturing process. Caution must be exercised when the vaccine is administered to subjects with hypersensitivity to betapropiolactone, neomycin, and other antibiotics of the same class.

If Rabies Immunoglobulin is indicated in addition to Rabies Vaccine BP, then it must be administered at a different anatomical site to the vaccination site.

Rabies Vaccine BP should not be administered to patients with bleeding disorders such as haemophilia or thrombocytopenia, or to persons on anticoagulant therapy unless the potential benefit clearly outweighs the risk of administration. If the decision is taken to administer Rabies Vaccine BP in such persons, it should be given with caution with steps taken to avoid the risk of haematoma formation following injection.

The tip caps of the pre-filled syringes contain a natural rubber latex derivative, which may cause severe allergic reactions in latex sensitive individuals.

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded

Paediatric population

The potential risk of apnoea and the need for respiratory monitoring for 48-72 h should be considered when administering the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation) and particularly for those with a previous history of respiratory immaturity.

4.5 Interaction with other medicinal products and other forms of interaction

Immunosuppressive treatments, including long-term systemic corticosteroid therapy, may interfere with antibody production and cause the failure of the vaccination. It is therefore advisable to perform a serological test 2 to 4 weeks after the last injection (see also Section 4.2).

There are no clinical data available on the concurrent administration of Rabies Vaccine BP with other vaccines. Official recommendations should be followed with regard to co-administration with other vaccines or drugs.

Separate injection sites and separate syringes must be used in case of concomitant administration with any other medicinal product, including rabies immunoglobulins.

As rabies immunoglobulin interferes with development of immune response to the vaccine, the recommendation of administration of rabies immunoglobulin must be strictly followed.

4.6 Fertility, pregnancy and lactation

Pregnancy

Data on limited number of exposed pregnancies do not allow a conclusion on the potential risk of Rabies HDCV for pregnancy or for the health of the foetus/newborn child. Due to the severity of disease, pregnancy is not considered a contraindication to post exposure prophylaxis. If there is substantial risk of exposure to rabies, pre-exposure prophylaxis may also be indicated during pregnancy.

Breastfeeding

Due to the severity of the disease, breast feeding is not considered a contraindication and treatment must not be discontinued. It is not known whether this vaccine is excreted in human breast milk, thus no recommendation on continuation/discontinuation of breastfeeding can be made.

Fertility

Rabies Vaccine BP has not been evaluated for impairment of male or female fertility.

4.7 Effects on ability to drive and use machines

No adverse effects reported.

4.8 Undesirable effects

Summary of the safety profile

In clinical studies, more than 1,600 subjects, including approximately 600 children and adolescents, received at least one dose of Rabies Vaccine BP.

The adverse reactions were generally of mild intensity and appeared within 3 days after vaccination. Most reactions resolved spontaneously within 1 to 3 days after onset.

Most frequent adverse reactions in all age groups were injection site pain, headache, malaise and myalgia.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Rabies vaccines, ATC Code: J07BG01.

Mechanism of action

Protection after vaccination is provided by the induction of rabies neutralizing antibodies (RNA).

Clinical studies were conducted to assess the immunogenicity of the vaccine in both pre-exposure and post-exposure situations. A rabies neutralizing antibody titer ≥ 0.5 IU/ml, is considered to confer protection.

Pre-exposure prophylaxis

In clinical trials assessing a 3-dose regimen (D0, D7, D28 (or D21))in both adults and children, almost all subjects achieved an adequate immune response with rabies neutralizing antibody titers ≥ 0.5 IU/mL by 2 weeks after the end of the primary series.

A ten-year follow-up in 17 subjects who received a 3-dose regimen (D0, D7, D28) followed by a booster dose 1 year later has shown persistence of immune response with rabies neutralizing antibody titers ≥ 0.5 IU/mL up to 10 years in 96.2% (CI95% 88.8; 100) of subjects.

Post exposure prophylaxis

In clinical trials assessing the 5-dose Essen regimen (D0, D3, D7, D14, D28) in both children and adults, with or without immunoglobulin, Rabies Vaccine BP elicited adequate rabies neutralizing antibody titers (≥ 0.5 IU/mL) in almost all subjects by D14 and in all of them by D42.

In a phase 2 trial, 124 healthy seronegative adults received the 5-dose Essen regimen (D0, D3, D7, D14, D28) IM and human rabies immunoglobulin at D0. All vaccinees reached a rabies neutralizing antibody titer ≥ 0.5 IU/mL by D14 with a maximum level on D42. One year later, protective level of rabies neutralizing antibodies was maintained in 98.3% (CI95% 93.9; 99.8) of subjects.

In a clinical trial simulating post-exposure prophylaxis, 47 previously immunised adult subjects received 2 doses of Rabies Vaccine BP 3 days apart (D0 and D3), 1 year after primary immunisation. Protective rabies neutralizing antibody titer (≥ 0.5 IU/mL) was reached by D7 in all subjects.

Paediatric population

Immunogenicity of the pre-exposure schedule (3 doses on D0, D7 and D28 by IM route) has been assessed at D42 in 112 subjects from 2 to 17 years of age included in VRV06 study, and in 190 subjects from 5 to 13 years of age included in RAC03396 study. All vaccinees reached a rabies neutralizing antibody titer ≥ 0.5 IU/ml at D42.
