For one dose of 0.5ml

This vaccine complies with the WHO recommendations (Northern Hemisphere) and EU decision for the 2016/2017 season.

Agrippal may contain traces of eggs such as ovalbumin or chicken proteins, kanamycin and neomycin sulphate, formaldehyde, cetyltrimethylammonium bromide (CTAB), polysorbate 80 and barium sulphate which are used during the manufacturing process (see section 4.3).

For a full list of excipients see section 6.1.

3. Pharmaceutical form

Suspension for injection in pre-filled syringe.

The vaccine appears as a clear liquid.

4. Clinical particulars
4.1 Therapeutic indications

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

Agrippal is indicated in adults and children from 6 months of age.

The use of Agrippal should be based on official recommendations.

4.2 Posology and method of administration

Posology

Adults: 0.5 ml.

Paediatric population

Children from 36 months onwards: 0.5 ml

Children from 6 months to 35 months: Clinical data are limited. Dosages of 0.25 ml or 0.5 ml may be given. The dose given should be in accordance with the existing national recommendation.

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

Children less than 6 months: the safety and efficacy of Agrippal in children less than 6 months have not been established.

No data are available.

Method of administration

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

For instructions for preparation of the medicinal product before administration, see section 6.6.

4.3 Contraindications

Hypersensitivity to the active substances, to any of the excipients listed in section 6.1 or residues (e.g. egg or chicken proteins such as ovalbumin).

Known hypersensitivity to any of the following substances, possibly contained as residues: kanamycin and neomycin sulphate, formaldehyde, cetyltrimethylammonium bromide (CTAB), barium sulphate and polysorbate 80.

Previous anaphylactoid reaction to any influenza vaccination.

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.

Agrippal should under no circumstances be administered intravascularly.

Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress-related reactions can occur following, or even before, any vaccination as a psychogenic response to the needle injection. This can be accompanied by several neurological signs such as transient visual disturbance, paraesthesia and tonic-clonic limb movements during recovery. It is important that procedures are in place to avoid injury from faints.

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

Latex-sensitive individuals:

Although no natural rubber latex is detected in the syringe tip cap, the safe use of Agrippal in latex-sensitive individuals has not been established.

4.5 Interaction with other medicinal products and other forms of interaction

Agrippal 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.

A higher frequency of some solicited systemic reactions has been reported in subjects vaccinated with trivalent inactivated influenza vaccine and pneumococcal vaccine compared with trivalent inactivated influenza vaccine alone.

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 results. The transient false positive reactions could be due to the IgM response by the vaccine.

4.6 Fertility, pregnancy and lactation

Pregnancy

Inactivated influenza vaccines can be used in all stages of pregnancy. Larger datasets on safety are available for the second and third trimester, compared with the first trimester; however, data from worldwide use of inactivated influenza vaccines do not indicate any adverse foetal and maternal outcomes attributable to the vaccine.

Breastfeeding

Agrippal may be used during breastfeeding.

Fertility

No fertility data are available.

4.7 Effects on ability to drive and use machines

Agrippal has no or negligible influence on the ability to drive and use machines.

Adverse reactions observed from clinical trials

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

Very common (≥1/10); common (≥1/100, <1/10); uncommon (≥1/1,000, <1/100); rare (≥1/10,000, < 1/1,000); very rare (<1/10,000), including isolated reports.

Vasculitis associated in very rare cases with transient renal involvement.

Skin and subcutaneous tissue disorders

Generalised skin reactions including pruritus, urticaria or non-specific rash.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

4.9 Overdose

Overdosage is unlikely to have any untoward effect.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Not applicable.

5.3 Preclinical safety data

Non-clinical data reveal no special hazard for humans based on animal studies that are appropriate for the safety assessment of vaccines.

6.4 Special precautions for storage

Store in a refrigerator (2°C – 8°C). Do not freeze. Discard if the vaccine has been frozen. Keep the syringe in the outer carton in order to protect from light.

Not all pack sizes may be marketed.

6.6 Special precautions for disposal and other handling

The vaccine should be allowed to reach room temperature before use.

Shake before use. After shaking, the normal appearance of Agrippal is a clear liquid.

Visually inspect Agrippal for the presence of particulate matter or discoloration prior to administration. If either of these conditions exists, do not use the content.

When using a pre-filled syringe supplied without a needle, remove the tip cap from the syringe and then attach a suitable needle for administration.

When administering a half dose (0.25 ml), discard half the contained volume by holding the syringe in an upright position and pushing the plunger until the front edge of the stopper reaches the mark indicated on the syringe barrel. Inject the entire remaining 0.25 ml contents of the syringe.

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