For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Suspension for injection in prefilled syringe.



The vaccine, after shaking gently, is a slightly whitish and opalescent liquid.



4. Clinical Particulars



4.1 Therapeutic Indications



Prophylaxis of influenza, especially in those who run an increased risk of associated complications.



The use of Inactivated Influenza Vaccine (Split Virion) BP should be based on official recommendations.



4.2 Posology And Method Of Administration



Adults and children from 36 months: 0.5 ml.



Children from 6 months to 35 months: clinical data are limited. Dosages of 0.25 ml or 0.5 ml have been used.



For children who have not previously been vaccinated, a second dose should be given after an interval of at least 4 weeks.



Immunisation should be carried out by intramuscular or deep subcutaneous injection.



For instructions for preparation, see section 6.6.



4.3 Contraindications



Hypersensitivity to the active substances, to any of the excipients and to residues e.g. eggs, such as ovalbumin, chicken proteins.



The vaccine may contain other residues of the following substances: neomycin, formaldehyde and octoxinol 9.



Immunisation shall be postponed in patients with febrile illness or acute infection.



4.4 Special Warnings And Precautions For Use



As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of an anaphylactic event following the administration of the vaccine.



Inactivated Influenza Vaccine (Split Virion) BP should under no circumstances be administered intravascularly.



Antibody response in patients with endogenous or iatrogenic immunosuppression may be insufficient.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Inactivated Influenza Vaccine (Split Virion) BP may be given at the same time as other vaccines. Immunisation should be carried out on separate limbs. It should be noted that the adverse reactions may be intensified.



The immunological response may be diminished if the patient is undergoing immunosuppressant treatment.



Following influenza vaccination, false positive results in serology tests using the ELISA method to detect antibodies against HIV1, Hepatitis C and especially HTLV1 have been observed. The Western Blot technique disproves the false-positive ELISA test results. The transient false positive reactions could be due to the IgM response by the vaccine.



4.6 Pregnancy And Lactation



The limited data from vaccinations in pregnant women do not indicate that adverse foetal and maternal outcomes were attributable to the vaccine. The use of this vaccine may be considered from the second trimester of pregnancy. For pregnant women with medical conditions that increase their risk of complications from influenza, administration of the vaccine is recommended, irrespective of their stage of pregnancy.



Inactivated Influenza Vaccine (Split Virion) BP may be used during lactation.



4.7 Effects On Ability To Drive And Use Machines



The vaccine is unlikely to produce an effect on the ability to drive and use machines.



4.8 Undesirable Effects



ADVERSE REACTIONS OBSERVED FROM CLINICAL TRIALS:



The safety of trivalent inactivated influenza vaccines is assessed in open label, uncontrolled clinical trials performed as annual update requirement, including at least 50 adults aged 18 – 60 years of age and at least 50 elderly aged 61 years or older. Safety evaluation is performed during the first 3 days following vaccination.



The following undesirable effects have been observed during clinical trials with the following frequencies:
