3. PHARMACEUTICAL FORM

Suspension for injection.

Tetravac is a sterile and whitish turbid suspension.

4. CLINICAL PARTICULARS

4.1 Therapeutic indications

Active immunisation against diphtheria, tetanus, pertussis and poliomyelitis

• for primary vaccination in infants,

• for booster in children who have previously received a primary vaccination with a diphtheria-tetanus-whole-cell or acellular pertussis-poliomyelitis vaccine.

4.2 Posology and method of administration

Posology

Primary vaccination:

Primary immunisation can be given as 3 doses at an interval of 1-2 months starting at the age of 2 or 3 months or as 2 doses at an interval of 2 months starting at the age of 3 months and a third dose at the age of 12 months [according to national vaccination policies].

Booster:

A fourth dose should be administered within the second year of life to children who received Tetravac (or a diphtheria-tetanus-whole-cell or acellular pertussis-poliomyelitis vaccine, whether mixed or not with the freeze-dried conjugate Haemophilus influenzaetype b vaccine) as a three-dose primary series between the ages of 2-6 months.

More data (e.g. epidemiological, clinical trial follow up) are required to establish the need for additional doses of acellular pertussis vaccines.

Tetravac can also be administered to children aged 5-12 years who were previously immunised with an acellular vaccine or four doses of whole-cell vaccine.

Tetravac is a high dose diphtheria vaccine. The use of a low dose diphtheria may be recommended at an earlier age than 12 years in some countries depending on national policies.

Method of administration

Tetravac must be administered intramuscularly. The recommended injection sites are the antero-lateral aspect of the upper thigh in infants and the deltoid muscle in older children.

The intradermal or intravenous routes must not be used. Do not administer by intravascular injection: ensure that the needle does not penetrate a blood vessel.

4.3 Contraindications

Known systemic hypersensitivity reaction to any component of Tetravac listed in section 6.1 or a vaccine containing the same substances or to pertussis vaccines (acellular or whole cell pertussis).

As with other vaccines, the vaccination with Tetravac should be postponed in case of:

4.4 Special warnings and precautions for use

Special warnings

• As each dose may contain undetectable traces of glutaraldehyde, neomycin, streptomycin and polymyxin B, caution should be exercised when the vaccine is administered to subjects with hypersensitivity to these substances.

• The immunogenicity of the vaccine may be reduced by immunosuppressive treatment or immunodeficiency. It is recommended to postpone vaccination until the end of such treatment or disease. Nevertheless, vaccination of subjects with chronic immunodeficiency such as HIV infection is recommended even if the antibody response may be limited.

• If Guillain-Barré syndrome or brachial neuritis has occurred following receipt of prior vaccine containing tetanus toxoid, the decision to give any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks, such as whether or not the primary immunization schedule has been completed. Vaccination is usually justified for infants whose primary immunization schedules are incomplete (i.e., fewer than three doses have been received).

• The potential risk of apnoea and the need for respiratory monitoring for 48-72 h should be considered when administration the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation) and particularly for those with a previous history of respiratory immaturity. As the benefit of vaccination is high in this group of infants, vaccination should never be withheld of delayed.

• Tetravac contains phenylalanine which may be harmful to people with phenylketonuria (PKU).

• Tetravac contains small amounts of ethanol (alcohol), less than 100 mg per dose.

Precautions for use

• Do not administer by intravascular injection: ensure that the needle does not penetrate a blood vessel.

• As with all injectable vaccines, the vaccine must be administered with caution to subjects with thrombocytopenia or a bleeding disorder since bleeding may occur following an intramuscular administration to these subjects.

• Prior to administration of any dose of Tetravac, the parent or guardian of the recipient must be asked about the personal history of the recipient, family history and recent health status, including immunization history, current health status and any adverse event after previous immunizations.

• If any of the following events are known to have occurred in temporal relation to receipt of pertussis-containing vaccine, the decision to give further doses of pertussis-containing vaccine should be carefully considered:

• Temperature of ≥40.0°C within 48 hours not due to another identifiable cause.

• Collapse or shock-like state (hypotonic-hyporesponsive episode) within 48 hours of vaccination.

• Persistent, inconsolable crying lasting ≥ 3 hours, occurring within 48 hours of vaccination.

• Convulsions with or without fever, occurring within 3 days of vaccination.

• Before the injection of any biological, the person responsible for administration must take all precautions known for the prevention of allergic or any other reactions. 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.

4.5 Interaction with other medicinal products and other forms of interaction

Except in the case of a immunosuppressive therapy (see section 4.4), no significant clinical interaction with other treatments or biological products has been reported. A specific interaction study has been done on co-administration of Tetravac, used to reconstitute freeze-dried Act-HIB vaccine (Haemophilus influenzae type b), and MMR.

4.6 Fertility, pregnancy and lactation

Not applicable. This vaccine is intended only for paediatric use.

4.7 Effects on ability to drive and use machines

Not relevant.

4.8 Undesirable effects

The adverse events are ranked under headings of frequency using the following convention:

• Very common: ≥1/10

• Common: ≥1/100 and <1/10

• Uncommon: ≥ 1/1000 and <1/100

• Rare: ≥1/10 000 and <1/1000

• Very rare: <1/10 000

• Not known: cannot be estimated from the available data. Based on spontaneous reporting, these adverse events have been very rarely reported following commercial use of Tetravac. Because events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.

In clinical studies infants who received Tetravac administered alone or simultaneously with Act-HIB^as a primary series the most frequently reported reactions include local reactions at the injection site, abnormal crying, anorexia, and irritability.

These signs and symptoms usually occur within 48 hours following the vaccination and may continue for 48-72 hours. They resolve spontaneously without requiring specific treatment.

After the primary series, the frequencies of injection site reactions tend to increase with the booster dose.

Tetravac safety profile does not differ significantly between the different age groups however some adverse events such as myalgia, malaise and headache are specific to children ≥ 2 years of age.

Hypotonic hyporesponsive episodes have not been reported following the use of Tetravac during clinical studies but have been reported for other pertussis vaccines.

Oedematous reaction affecting one or both lower limbs may occur following vaccination with Haemophilus influenzae type b containing vaccines. If this reaction occurs, it does so mainly after primary injections and is observed within the first few hours following vaccination. Associated symptoms may include cyanosis, redness, transient purpura and severe crying. All events resolve spontaneously without sequelae within 24 hours.

One such case has been reported during clinical trials performed with diphtheria-tetanus-acellular pertussis-poliomyelitis vaccine Tetravac administered simultaneously with the conjugate Haemophilus influenzae type b vaccine in two separate injection sites.

When Tetravac is indicated for administration to children aged from 5 to 12 years as a late booster, reactions to Tetravac in children in this age group are less or equally frequently reported than after administration of DTP-IPV (whole-cell pertussis) or DT-IPV, respectively, at the same age.

There have been very rare reports of brachial neuritis and Guillain-Barré Syndrome after administration of other tetanus toxoid containing vaccines.

Additional information on special populations:

Apnoea in very premature infants (≤ 28 weeks of gestation) (see section 4.4).

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.

4.9 Overdose

Not applicable.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Combined bacterial and viral vaccines (diphtheria-pertussis-poliomyelitis-tetanus),

ATC code: J07C A02

Immune response after primary vaccination:

Immunogenicity studies in infants given three doses of Tetravac starting at 2 months of age have shown that all (100%) developed a seroprotective antibody level (0.01 IU/mL) to both diphtheria and tetanus antigens.

For pertussis, more than 87% of infants achieved a four-fold rise in PT and FHA antibody titres one to two months after completion of the primary vaccination.

At least 99.5% of children had post-immunisation titres above the threshold of 5 (reciprocal of dilution in seroneutralisation) against poliovirus types 1, 2 and 3, and were considered protected against poliomyelitis.

In the Senegal efficacy trial following a 3 dose primary regimen and after 18 months without booster, the protective efficacy of this acellular pertussis vaccine was found to be lower than the Pasteur Mérieux whole cell pertussis control vaccine. However, lower reactogenicity was demonstrated for this acellular pertussis vaccine in 2 controlled clinical studies when compared to this same whole cell pertussis vaccine.

Immune response after booster injection:

Immunogenicity studies in toddlers in the second year of life who had received a 3‑dose primary vaccination series with Tetravac have shown high antibody responses to all components following a fourth dose (booster).

Studies in children 12 to 24 months of age who were given a 3-dose primary immunisation course with whole-cell pertussis vaccines, DTP-IPV (Tetracoq) or DTP-IPV-ACT-HIB (Pentact-HIB/PENTACOQ), have shown that a booster dose with Tetravac is safe and immunogenic for all components of the vaccine.

Studies in children 5 to 12 years of age who were given 4 doses of whole-cell pertussis vaccines, DTP-IPV (Tetracoq) or DTP-IPV-Act-HIB (Pentact-HIB/PENTACOQ), have shown that a booster dose with Tetravac is immunogenic for all components and is well tolerated.
