Adults:
Dosage: For adults and children over 36 months of age, the recommended dose is 0.5 ml. For children aged 6 to 35 months, clinical data remain limited, and either a 0.25 ml or 0.5 ml dose has been used. Children who have not been vaccinated before should receive a second dose at least 4 weeks after the first. If a half dose (0.25 ml) is needed, discard half of the volume in the syringe (up to the mark on the barrel) before giving the injection. The vaccine is given by intramuscular or deep subcutaneous injection. Let it warm to room temperature and shake it well before use. Protection typically develops within 2 to 3 weeks of vaccination. Immunity to the matching or closely related strains usually lasts 6 to 12 months, though this can vary.

Cautions & Contraindications
Warnings & Precautions
Antibody response may be inadequate in patients whose immune system is weakened, whether from an underlying illness or from medicines that suppress immunity. As with any injectable vaccine, appropriate medical treatment and supervision should always be on hand in the rare event of an anaphylactic reaction after vaccination. Under no circumstances should Vaxigrip Tetra be given by intravascular injection.
Contraindications
Hypersensitivity to the active substances, to any of the excipients, or to residual substances such as eggs and chicken proteins (including ovalbumin). Trace residues from manufacturing may also be present, including kanamycin and neomycin sulphate, formaldehyde, cetyltrimethylammonium bromide (CTAB), and polysorbate 80, and can trigger reactions in sensitive individuals. Vaccination should be delayed in anyone currently experiencing a febrile illness or acute infection until they have recovered.
