The safety and efficacy of Adjupanrix in children less than 6 months have not been established.

Method of administration

Immunisation should be carried out by intramuscular injection.

6.5. Nature and contents of container

One pack containing:

  • one pack of 50 vials (type I glass) of 2.5 ml suspension with a stopper (butyl rubber).
  • two packs of 25 vials (type I glass) of 2.5 ml emulsion with a stopper (butyl rubber).

The volume after mixing 1 vial of suspension (2.5 ml) with 1 vial of emulsion (2.5 ml) corresponds to 10 doses of vaccine (5 ml).

6.6. Special precautions for disposal and other handling

Adjupanrix consists of two containers:

Suspension: multidose vial containing the antigen,

Emulsion: multidose vial containing the adjuvant.

Prior to administration, the two components should be mixed.

Instructions for mixing and administration of the vaccine:

1. Before mixing the two components, the emulsion (adjuvant) and suspension (antigen) should be allowed to reach room temperature (for a minimum of 15 minutes); each vial should be shaken and inspected visually for any foreign particulate matter and/or abnormal physical appearance. In the event of either being observed (including rubber particles from the stopper), do not mix the vaccine.

2. The vaccine is mixed by withdrawing the entire contents of the vial containing the adjuvant by means of a 5 ml syringe and by adding it to the vial containing the antigen. It is recommended to equip the syringe with a 23-G needle. However, in the case this needle size would not be available, a 21-G needle might be used. The vial containing the adjuvant should be maintained in upside down position to facilitate the withdrawal of the full content.

3. After the addition of the adjuvant to the antigen, the mixture should be well shaken. The mixed vaccine is a whitish to yellowish homogeneous milky liquid emulsion. In the event of other variation being observed, do not administer the vaccine.

4. The volume of the Adjupanrix vial after mixing is at least 5 ml. The vaccine should be administered in accordance with the recommended posology (see section 4.2).

5. The vial should be shaken prior to each administration and inspected visually for any foreign particulate matter and/or abnormal physical appearance. In the event of either being observed (including rubber particles from the stopper), do not administer the vaccine.

6. Each vaccine dose of 0.5 ml or 0.25 ml or 0.125 ml is withdrawn into a syringe with appropriate graduation for injection and administered intramuscularly. It is recommended to equip the syringe with a needle gauge not larger than 23-G.

7. After mixing, use the vaccine within 24 hours. The mixed vaccine can either be stored in a refrigerator (2°C-8°C) or at room temperature not exceeding 25°C. If the mixed vaccine is stored in a refrigerator, it should be allowed to reach room temperature (for a minimum of 15 minutes) before each withdrawal.

Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
