POSOLOGY AND METHOD OF ADMINISTRATION 

Posology

Primary Vaccination::

Subjects 9 months of age and over one 0.5 mL single injection of the reconstituted vaccine.

Booster

- Paediatric population

If a long term protection is required, one 0.5 mL dose of IMOJEV® should be given as a long booster dose after primary vaccination. The booster dose should be given preferably 12 months after primary vaccination and can be given up to 24 months after primary vaccination. One 0.5 mL dose of Imojev can also be given as a booster vaccination in children who were previously given an inactivated Japanese encephalitis vaccine for primary vaccination, in accordance with the recommended timing for the booster of the inactivated Japanese encephalitis vaccine.

*Immunity is maintained at a high level at least 4 years after the booster dose when the vaccine used for primary vaccination is JE-CV (Imojev)

- Adult population:

The need for and timing of a possible booster dose have not yet been determined.

Method of administration

Once the freeze-dried vaccine has been completely reconstituted using the diluent provided, it is administered via the subcutaneous route.

In subjects 2 years of age and over, the recommended injection site is the deltoid region of

the upper arm.

In subjects between 9 and 24 months of age, the recommended injection site is the anterolateral aspect of the thigh or the deltoid region.

Do not administer by intravascular injection

IMOJEV® must not be mixed with any other injectable vaccine(s) or medicinal product(s)

Instructions for reconstitution and administration

Using aseptic technique, IMOJEV® vaccine is reconstituted by injecting all the 0.4% sodium chloride solution into the vial of freeze-dried vaccine, using the syringe and one of the needles provided in the carton. The vial is gently swirled. After complete dissolution, a 0.5 ml dose of the reconstituted suspension is withdrawn into this same syringe. For injection, the syringe is fitted with the second needle provided in the package.

The product should be used once reconstituted.

CONTRAINDICATIONS

IMOJEV® should not be administered to anyone with a history of severe allergic reaction to any component of the vaccine or after previous administration of the vaccine or a vaccine

containing the same components or constituents.

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

Congenital or acquired immune deficiency impairing cellular immunity, including immunosuppressive therapies such as chemotherapy, high doses of systemic corticosteroids given generally for 14 days or more.

IMOJEV® must not be administrated to persons with symptomatic HIV infection or with

asymptomatic HIV infection when accompanied by evidence of impaired immune function.

SPECIAL WARNINGS AND SPECIAL 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. For patients following a treatment with high doses of systemic corticosteroids given for 14 days or more, it is advisable to wait for at least one month or more following the interruption of therapy before carrying out the vaccination until immune function has recovered. Do not administer by intravascular injection.

INTERACTIONS

Separate injection sites and separate syringes should be used when other vaccines are concomitantly administered with IMOJEV®.

From 12 months of age, IMOJEV may be administered at the same time with MMR vaccine. No studies on concomitant administration with vaccine against measles either stand alone or combined.

For children living in areas where risk for measles is high, IMOJEV® may be administered at the same time as measles vaccine, either stand alone or combined with mumps and/or rubella vaccines, from 9 months of age.

IMOJEV® may be administered to adults at the same time as yellow fever vaccine

In the case of immunosuppressive therapy or corticosteroid therapy see contraindication and special warning and precautions for use

Administering the vaccine in subjects who have previously received immunoglobulins:

In order to avoid any neutralisation of the attenuated viruses contained in the vaccine, vaccination must generally not be performed within 6 weeks, and preferably not within      3 months of injection of immunoglobulins or blood products containing immunoglobulins,

such as blood or plasma.

PREGNANCY AND LACTATION

Animal studies did not indicate direct or indirect harmful effects with respect to pregnancy,

embryo-foetal development, parturition or post-natal development 

As with all live attenuated vaccines, pregnancy constitutes a contra-indication

Animal studies did not indicate direct or indirect harmful effects with respect to lactation. It is not known whether this vaccine is excreted in human milk.

IMOJEV® vaccination is contraindicated in breastfeeding women.
