S_4_1_therapeutic_indications
Prophylaxis of influenza disease in adults and children from 6 months of age. Influenza vaccine TIV Viatris should be used in accordance with official recommendations.
S_4_2_posology_administration
Posology Adults: 0.5 ml. Paediatric population Children from 6 months to 17 years of age: 0.5 ml. Children less than 9 years of age, who have not previously been vaccinated with a seasonal influenza vaccine: a second dose of 0.5 ml should be given after an interval of at least 4 weeks. Infants less than 6 months of age: the safety and efficacy of Influenza vaccine TIV Viatris have not been established. No data are available. Method of Administration Immunisation should be carried out by intramuscular or deep subcutaneous injection. The preferred sites for intramuscular injection are the anterolateral aspect of the thigh (or the deltoid muscle if muscle mass is adequate) in children 6 months through 35 months of age, or the deltoid muscle in children from 36 months of age and adults. Precautions to be taken before handling or administering the medicinal product: see section 6.6 For instructions for preparation of the medicinal product before administration, see section 6.6.
S_4_3_contraindications
Hypersensitivity to the active substances, to any of the excipients listed in section 6.1 or to any component that may be present as traces such as eggs (ovalbumin, chicken proteins), formaldehyde, cetyltrimethylammonium bromide, polysorbate 80 or gentamicin. Immunisation shall be postponed in patients with febrile illness or acute infection.
S_4_4_warnings_precautions
Traceability In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded. 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. Influenza vaccine TIV Viatris should under no circumstances be administered intravascularly. As with other vaccines administered intramuscularly, Influenza vaccine TIV Viatris should be given with caution to individuals with thrombocytopenia or any coagulation disorder since bleeding may occur following an intramuscular administration to these subjects. 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. Influenza vaccine TIV Viatris is not effective against all possible strains of influenza virus. Influenza vaccine TIV Viatris is intended to provide protection against those strains of virus from which the vaccine is prepared and to closely related strains. As with any vaccine, a protective immune response may not be elicited in all vaccinees. Antibody response in patients with endogenous or iatrogenic immunosuppression may be insufficient. Interference with serological testing: see section 4.5. Sodium and potassium content This medicine contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially ‘sodium- free’. This medicine contains potassium, less than 1 mmol (39 mg) per dose, i.e. essentially “potassium- free”.

S_4_6_pregnancy_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 influenza vaccine do not indicate any adverse fetal and maternal outcomes attributable to the vaccine. Breast-feeding Influenza vaccine TIV Viatris may be used during breast-feeding. Fertility No fertility data are available.

S_4_8_undesirable_effects
a. Summary of safety profile Data for Influvac sub-unit Tetra are relevant to Influenza vaccine TIV Viatris sub-unit TIV because both vaccines are manufactured using the same process. The safety of Influenza vaccine TIV Viatris was evaluated in several clinical trials and similar rates of solicited adverse reactions were observed in recipients of quadrivalent or trivalent formulations. Most reactions usually occurred within the first 3 days following vaccination and resolved spontaneously within 1 to 3 days after onset. The intensity of these reactions was generally mild. In all age groups, the most frequently reported local adverse reaction was vaccination site pain. The most frequently reported systemic adverse reactions in adults and children from 6 to 17 years of age were fatigue and headache, and for children from 3 to 5 years of age drowsiness, irritability and loss of appetite. The most frequently reported systemic adverse reactions in children from 6 months to 35 months of age were irritability/fussiness. In rare cases, allergic reactions may evolve to shock, angioedema (see section 4.4). b. Tabulated summary of adverse reactions The following have been observed during clinical trials with Influvac sub-unit Tetra or are resulting from post-marketing experience with Influenza vaccine TIV Viatris sub-unit TIV and Influvac sub-unit Tetra with the following frequencies: very common (=1/10); common (=1/100, <1/10); uncommon (=1/1,000, <1/100); and not known (adverse reactions from post-marketing experience; cannot be estimated from the available data).

S_5_1_pharmacodynamics
Pharmacotherapeutic group: Influenza vaccine, ATC Code: J07BB02. Mechanism of action Influenza vaccine TIV Viatris provides active immunisation against three influenza virus strains: an A/(H1N1) strain, an A/(H3N2) strain, and a B strain. It induces humoral antibodies against the haemagglutinins. These antibodies neutralise influenza viruses. Specific levels of haemagglutination-inhibition (HI) antibody titre post-vaccination with inactivated influenza virus vaccines have not been correlated with protection from influenza illness but the HI antibody titres have been used as a measure of vaccine activity. An immune response 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. Pharmacodynamic effects Data for Influvac sub-unit Tetra are relevant to Influenza vaccine TIV Viatris because both vaccines are manufactured using the same process. Efficacy and immunogenicity of Influenza vaccine TIV Viatris in children 6 - 35 months of age The efficacy of Influvac sub-unit Tetra was evaluated in a randomised, observer blind, non-influenza vaccine-controlled study (INFQ3003) conducted during 3 influenza seasons 2017 to 2019 in Europe and Asia. Healthy subjects aged 6 - 35 months received two doses of Influvac sub-unit Tetra (N=1005) or non-influenza control vaccine (N=995) approximately 28 days apart. Vaccine efficacy was assessed for the prevention of reverse transcription polymerase chain reaction (RT-PCR) -confirmed influenza A and/or B disease due to any influenza strain. All RT-PCR-positive specimens were further tested for viability in cell culture and to determine whether the circulating viral strains matched those in the vaccine.
