Bisogni insoddisfatti dei vaccini influenzali Da più di un decennio, la maggior parte delle patologie influenzali stagionali sono state causate da quattro ceppi di influenza (due sottotipi A e due lineage B).1-4 Non esistono dati che descrivano un possibile effetto cross-protettivo tra i lineage B come dimostrato invece tra tipi di A15 E’ difficile per le autorità sanitarie prevedere quale dei due lineage B includere nei vaccini influenzali trivalenti (TIV), e nelle ultime dieci stagioni il lineage B contenuto nei TIV è stato diverso da quello circolante (circa 50%).3,5,6 Quando il lineage contenuto nei TIV non ha concordanza con quello che predomina nella circolazione questi vaccini sono meno efficaci e l’impatto della patologia è maggiore.6–11 GSK’s QIVs è il primo vaccino antinfluenzale inattivato autorizzato per rispondere al bisogno identificato di ridurre il B-lineage mismatch.12 1 US CDC.

Vaccine lineage Composizione del vaccino per l’emisfero settentrionale e ceppi circolanti di tipo B in Europa, in America ed in Liguria In Liguria, un completo o parziale mismatching del tipo B, nell’ultima decade, si è osservato, oltre che nella stagione 2001/021, negli inverni 2004/05, 2005/06, 2007/08 e 2008/09, quasi sempre riconducibile alla co-circolazione dei 2 lineage 1.

New England Journal of Medicine 2013 Ogni anno, nel vaccino antiinfluenzale trivalente è incorporato soltanto un singolo antigene del lineage B che si prevede circolerà in quella stagione. Questa scelta nella metà delle volte ha portato a mismacth del B-lineage, rispetto al reale circolante. Una potenziale soluzione per ridurre al minimo la possibilità di una mancata corrispondenza del B-lineage è quello di includere entrambi i B-lineage nell’annuale vaccino contro l'influenza, come è stato recentemente suggerito dal Advisory Committee on Immunization Pratices del Centers for Disease Controll and Prevention e dalla World Health Organization. 16 Baden LR.

USA “There are two antigenically distinct lineages of influenza B viruses, referred to as Victoria and Yamagata lineages. Immunization against influenza B virus strains of one lineage provides only limited cross-protection against strains in the other lineage. Given this, and the challenge of predicting which B virus lineage will predominate during a given season, inclusion of two B virus strains (one from each lineage) in seasonal influenza vaccines may improve protection against circulating seasonal B virus strains.” “It is expected that the supply of IIV4 might be limited. Quadrivalent vaccines are designed to provide broader protection against circulating influenza B viruses in seasons during which the B virus contained in trivalent vaccines is not an optimal match to the predominant circulating B viruses. However, vaccination should not be delayed if only IIV3 is available. No preference is expressed for IIV4 over IIV3.” IIV3 = trivalent inactivated influenza vaccine; IIV4 = quadrivalent inactivated influenza vaccine US ACIP.

UK “until most, if not all, influenza vaccine manufacturers are supplying quadrivalent vaccines, it is unlikely that the number of doses of quadrivalent influenza vaccines available would meet the total demand for influenza vaccines” “Quadrivalent inactivated influenza vaccines are likely to provide better protection against influenza B compared with trivalent inactivated influenza vaccines” 1 “Live attenuated influenza vaccine (LAIV) was more effective against infection than inactivated influenza vaccines in children. Thus, LAIV should remain the vaccine of choice for children aged two to less than 18 years” 1 “The available quadrivalent inactivated vaccine should be the preferred vaccine for those aged three years and older who cannot receive LAIV”1 Update June 2014 JCVI minutes (not yet in Green Book): “After consideration of the data the Committee concluded that, all other factors being equal, QIV was preferable to trivalent inactivated influenza vaccine (TIV). However conclusions could not be drawn on the cost-effectiveness of QIV over TIV, from data provided by the sole manufacturer of QIV.” 2 QIV = quadrivalent inactivated influenza vaccine 1. UK JCVI.

Objective: Health economic models aim at simulating the clinical and economic impact of an immunization program Is the intervention worth the money? What is the most appropriate alternative? For QIV they are required since: Limited real-life data (i.e. effectiveness data) Epidemiological data of influenza B not available for all countries/ regions Limited number of QIV clinical trials/ immunogenicity To explore QIV’s impact on indirect protection (‘herd protection’) Cost of influenza and its complications Epidemiology (attack rate, excess hospitalizations and deaths) Demographics (pop. size, life expectancy, utility, % of at-risk people) Jit M, et al. Hum Vaccin Immunother. 2013; 4: 834-40. Vaccines coverage rates and vaccine price Health economics model Vaccine effectiveness What is an economic evaluation?

Decision Modelling for Health Economic Evaluation. Oxford, United Kingdom: Oxford University Press; 2007.(page 122 & 123) Key questions tackled by modeling the impact and benefits of QIV What is the additional health benefit of QIV vs. trivalent influenza vaccine (TIV) each year at the population level, in terms of: Cases avoided Hospitalizations avoided Public health benefits of QIV Deaths avoided Vaccine impact on blocking the chain of transmission Herd effect: Interaction between age groups What are the additional influenza related costs avoided with QIV versus TIV: Cost of influenza cases, GP visits, hospitalizations, productivity losses avoided Is it cost-effective to fund QIV every year instead of TIV? What is the incremental cost of QIV versus TIV over 1 year? Economic impact of QIV compared to its benefits Overall conclusions Two influenza B lineages have been co-circulating in the last decade A substantial mismatch has occurred between the influenza B virus represented in the seasonal vaccine and the circulating strain Fluarix Tetra® (D-QIV) has shown superior immunogenicity compared with TIV for the additional B strain with a similar safety profile to TIV Fluarix Tetra® (D-QIV) offers broader coverage than TIV, and has also been estimated to be costeffective compared to TIV in a UK model For UK only Prescribing Information – Refer to SmPC before prescribing.

Qualitative and quantitative composition: Each 0.5 ml dose contains Influenza virus (inactivated, split) of the following strains*: A/California/7/2009 (H1N1)pdm09-like strain used (NIB-74xp) derived from A/Christchurch/16/2010 15 micrograms HA**, A/Texas/50/2012 (H3N2) derived strains used (NYMC X223A) 15 micrograms HA**, B/Massachusetts/02/2012 derived strain used (NYMC BX-51B) (Yamagata lineage) 15 micrograms HA**, B/Brisbane/60/2008 (Victoria lineage) 15 micrograms HA**. This vaccine complies with the WHO recommendation (northern hemisphere) and EU decision for the 2014/2015 season. Fluarix Tetra may contain traces of eggs (such as ovalbumin, chicken proteins), formaldehyde, gentamicin sulphate and sodium deoxycholate which are used during the manufacturing process. *propagated in fertilized hens’ eggs from healthy chicken flocks. **haemagglutinin. Uses: Fluarix Tetra is indicated for active immunisation of adults and children from 3 years of age for the prevention of influenza disease caused by the two influenza A virus subtypes and the two influenza B virus types contained in the vaccine. Dosage and administration: Adults: 0.5 ml (0.5ml = 1 dose). Paediatric population: Children from 36 months onwards: 0.5 ml. For children aged < 9 years, who have not previously been vaccinated, a second dose should be given after an interval of at least 4 weeks. Children less than 3 years: the safety and efficacy of Fluarix Tetra in children less than 3 years have not been established. Immunisation should be carried out by intramuscular injection. Contraindications: Hypersensitivity to the active substances, to any of the excipients or to any component that may be present as traces such as eggs (ovalbumin, chicken proteins), formaldehyde, gentamicin sulphate and sodium deoxycholate. Immunisation shall be postponed in patients with febrile illness or acute infection. Special precautions and special warnings: It is good clinical practice to precede vaccination by a review of the medical history (especially with regard to previous vaccination and possible occurrence of undesirable events) and a clinical examination. 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. Antibody response in patients with endogenous or iatrogenic immunosuppression may be insufficient. Fluarix Tetra is not effective against all possible strains of influenza virus. Fluarix Tetra 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. Fluarix Tetra should under no circumstances be administered intravascularly. As with other vaccines administered intramuscularly, Fluarix Tetra should be given with caution to individuals with thrombocytopenia or any coagulation disorder since bleeding may occur following an intramuscular administration to these subjects. Syncope (fainting) can occur following, or even before, any vaccination especially in adolescents 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. Interaction with other medicinal products and other forms of interaction: No interaction studies have been performed. If Fluarix Tetra is to be given at the same time as another injectable vaccine, the vaccines should always be administered at different injection sites. 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. Pregnancy/lactation: 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. Fluarix Tetra may be used during breastfeeding. Undesirable effects reported in clinical trials: See SPC for full details. Very common: irritability, myalgia, injection site pain, fatigue. Common: appetite loss, drowsiness, headache, gastrointestinal symptoms (including nausea, vomiting, diarrhoea and/or abdominal pain), arthralgia, injection site redness, injection site swelling, shivering, fever Uncommon: dizziness, rash, injection site hematoma, injection site pruritus. In addition, the following adverse reactions were reported in previous Fluarix trials: Common: sweating, injection site induration. Undesirable effects reported during post marketing surveillance: There has been no post-marketing exposure to Fluarix Tetra. However, as all three of the influenza strains contained in Fluarix™ are included in Fluarix Tetra, the following adverse events that have been observed for Fluarix™ during post-marketing surveillance may occur in patients receiving Fluarix Tetra post-approval. Rare: transient lymphadenopathy, allergic reactions (including anaphylactic reactions), urticaria, pruritus, erythema, angioedema, influenza-like illness, malaise, neuritis, acute disseminated encephalomyelitis, Guillain-Barré syndrome. Spontaneous reports of Guillain-Barré syndrome have been received following vaccination with Fluarix; however, a causal association between vaccination and Guillain-Barré syndrome has not been established. Overdose: Overdosage is unlikely to have any untoward effect. Legal category: POM. Presentation: 0.5 ml suspension in prefilled syringe (Type I glass) with a plunger stopper (grey butyl rubber) with or without fixed needle – pack size of 1 or 10.Special precautions for storage: Store in a refrigerator (2 °C – 8 °C).

NAME OF THE MEDICINE Fluarix Tetra influenza vaccine (split virion, inactivated) DESCRIPTION Fluarix Tetra is an inactivated and purified split influenza vaccine. The antigen composition and strains for the 2014 influenza season corresponds to the following types: A/California/7/2009 (H1N1)pdm09-like virus A/Texas/50/2012 (H3N2)-like virus B/Massachusetts/2/2012-like virus The vaccine presents as a colourless to slightly opalescent suspension. The syringe should be shaken and inspected visually for any foreign particulate matter and/or variation of physical aspect prior to administration. In the event of either being observed, discard the vaccine. Any unused product of waste material should be disposed of in accordance with local requirements. Fluarix Tetra is for single use in one patient only. OVERDOSAGE Insufficient data are available. PRESENTATION AND STORAGE CONDITIONS Fluarix Tetra is presented in pre-filled syringes as pack sizes of 1 or 10. MA Nos. Australia: PM-2012-02287-3-2; Hong Kong/Macau: HK62235; Taiwan No. 000939 B/Brisbane/60/2008-like virus Fluarix Tetra is prepared using whole virus cultivated in embryonated hens' eggs. The virus is concentrated and purified by clarification, adsorption and centrifugation. The purified whole virus is then treated with the detergent sodium deoxycholate and again centrifuged, and the resulting antigen suspension is inactivated with formaldehyde. Suspension for injection. Fluarix Tetra is a colourless to slightly opalescent suspension. INDICATIONS Fluarix Tetra is a quadrivalent vaccine indicated for active immunisation of adults and children from 3 years of age for the prevention of influenza disease caused by the influenza virus types A and B contained in the vaccine. The use of Fluarix Tetra should be based on official recommendations CONTRAINDICATIONS Fluarix Tetra should not be administered to individuals with known hypersensitivity after previous administration of Fluarix Tetra or influenza vaccines or to any component of the vaccine. PRECAUTIONS Fluarix Tetra should under no circumstances be administered intravascularly. 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. As with other vaccines, vaccination with Fluarix Tetra should be postponed in individuals suffering from an acute severe febrile illness. The presence of a minor infection, such as a cold, should not result in the deferral of vaccination. It may be expected that in patients receiving immunosuppressive treatment or patients with immunodeficiency, an adequate immune response may not be elicited. Fluarix Tetra is not effective against all possible strains of influenza virus. Fluarix Tetra is intended to provide protection against those strains of virus from which the vaccine is prepared and to closely related strains. Patients with a history of Guillain-Barre Syndrome (GBS) with an onset within six weeks of an influenza vaccination may be at increased risk of again developing GBS if given influenza vaccine. Such risk should be weighed against the benefits to the individual patient of influenza vaccination. DOSAGE AND ADMINISTRATION Fluarix Tetra should under no circumstances be administered intravascularly. Dosage Fluarix Tetra should be administered as a single 0.5 ml injection. Children 3 years to less than 9 years of age who have not previously been vaccinated against influenza should receive a second dose of 0.5 ml after an interval of at least 4 weeks. Administration Vaccination should be carried out by intramuscular injection preferably into the deltoid muscle or anterolateral thigh (depending on the muscle mass).
