Dosage
:
Adults and children over 36 months of age: 0.5ml
Children from 6 to 35 months of age: clinical data are limited. Doses of 0.25 ml or 0.5 ml have been used.
Administrations
: For children who have not previously been vaccinated, a second dose should be given after an interval of at least 4 weeks. If half a dose (0.25 ml) is to be administered, discard half the contained volume (up to the mark indicated on the syringe barrel), before injection. Immunisation should be carried out by intramuscular or deep subcutaneous injection. The vaccine should be allowed to reach room temperature before use. Shake before use. Seroprotection is generally obtained within 2 to 3 weeks. The duration of postvaccinal immunity to homologous strains or to strains closely related to the vaccine strains varies but is usually 6-12 months.
Hypersensitivity to the active substances, to any of the excipients and to residues, e.g. eggs, chicken proteins, such as ovalbumin. The vaccine may contain residues of the following substances, e.g. kanamycin and neomycin sulphate, formaldehyde, cetyltrimethylammonium bromide (CTAB) and polysorbate 80. Immunisation shall be postponed in patients with febrile illness or acute infection.
Antibody response in patients with endogenous (due to illness) or iatrogenic (due to medicine) immunosuppression (poor immune response) may be insufficient. As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of a rare anaphylactic event following the administration of the vaccine. Influvax Tetra should under no circumstances be administered intravascularly.
