One 0.5‑mL dose |
a One dose or two doses (0.5‑mL each) depending on vaccination history as per the annual Advisory Committee on Immunization Practices (ACIP) recommendation on prevention and control of influenza with vaccines. If two doses, administer each 0.5‑mL dose at least 4 weeks apart.
Shake well before administration. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If either of these conditions exists, the vaccine should not be administered.
Attach a sterile needle to the prefilled syringe and administer intramuscularly.
The preferred site for intramuscular injection is the deltoid muscle of the upper arm. Do not inject in the gluteal area or areas where there may be a major nerve trunk.
Do not administer this product intravenously, intradermally, or subcutaneously.
FLUARIX is a suspension for injection. Each 0.5-mL dose is supplied in single-dose prefilled TIP‑LOK® syringes.
Do not administer FLUARIX to anyone with a history of severe allergic reactions (e.g., anaphylaxis) to any component of the vaccine, including egg protein, or following a previous administration of any influenza vaccine [see Description (11)].
If Guillain‑Barré syndrome (GBS) has occurred within 6 weeks of receipt of a prior influenza vaccine, the decision to give FLUARIX should be based on careful consideration of the potential benefits and risks.
The 1976 swine influenza vaccine was associated with an increased frequency of GBS. Evidence for a causal relation of GBS with subsequent vaccines prepared from other influenza viruses is inconclusive. If influenza vaccine does pose a risk, it is probably slightly more than one additional case/one million persons vaccinated.
Syncope (fainting) can occur in association with administration of injectable vaccines, including FLUARIX. Syncope can be accompanied by transient neurological signs such as visual disturbance, paresthesia, and tonic-clonic limb movements. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope.
Prior to administration, the healthcare provider should review the immunization history for possible vaccine sensitivity and previous vaccination‑related adverse reactions. Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of FLUARIX.
If FLUARIX is administered to immunosuppressed persons, including individuals receiving immunosuppressive therapy, the immune response may be lower than in immunocompetent persons.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared with rates in the clinical trials of another vaccine, and may not reflect the rates observed in practice. There is the possibility that broad use of FLUARIX could reveal adverse reactions not observed in clinical trials.
Adults
In adults, the most common (≥10%) local adverse reactions and general adverse events observed with FLUARIX were pain and redness at the injection site, muscle aches, fatigue, and headache.
FLUARIX has been administered to 10,317 adults aged 18 through 64 years and 606 subjects aged 65 years and older in 4 clinical trials.
One of the 4 clinical trials was a randomized, double-blind, placebo-controlled trial that evaluated a total of 952 subjects: FLUARIX (N = 760) and placebo (N = 192). The population was aged 18 through 64 years (mean: 39.1), 54% were female and 80% were white. Solicited events were collected for 4 days (day of vaccination and the next 3 days) (Table 2). Unsolicited events that occurred within 21 days of vaccination (Day 0 to 20) were recorded using diary cards supplemented by spontaneous reports and a medical history as reported by subjects.

b NCT00197288.
Unsolicited adverse events that occurred in ≥1% of all recipients of FLUARIX or the comparator influenza vaccine in the 21-day post-vaccination period included headache (2.8% versus 2.3%), back pain (1.5% versus 0.4%), pain in extremity (1.2% versus 0.7%), pharyngolaryngeal pain (1.2% versus 0.9%), cough (1.1% versus 0.9%), fatigue (1.1% versus 0.7%), nasopharyngitis (1.0% versus 1.3%), nausea (0.4% versus 1.0%), arthralgia (0.3% versus 1.0%), and injection site pruritus (0.2% versus 1.0%).
A double-blind, placebo-controlled trial in subjects aged 18 through 64 years randomized (2:1) to receive FLUARIX (N = 5,103) or placebo (N = 2,549) was conducted to evaluate the efficacy of FLUARIX. In the total population, 60% were female and 99.9% were white. In a subset (FLUARIX [N = 305] and placebo [N = 155]), unsolicited events that occurred within 21 days of vaccination (Day 0 to 20) were recorded on diary cards. The percentage of subjects reporting at least one unsolicited event was similar among the groups (24.3% for FLUARIX and 22.6% for placebo). Unsolicited adverse events that occurred in ≥1% of recipients of FLUARIX and at a rate greater than placebo included injection site pain (5.2% versus 1.3%), dysmenorrhea (1.3% versus 0.6%), and migraine (1.0% versus 0.0%).
Incidence of Adverse Events Reported in ≥1% of Subjects in Non-US Clinical Trials: The following additional adverse events have been observed in adults in non-US clinical trials with FLUARIX. No adverse events were observed at an incidence of >10%.
General Disorders and Administration Site Conditions: Injection site ecchymosis, injection site induration, malaise.
Infections and Infestations: Rhinitis.
Musculoskeletal and Connective Tissue Disorders: Musculoskeletal pain, neck pain.
Skin and Subcutaneous Tissue Disorders: Sweating.
Serious Adverse Events: In the 4 clinical trials in adults (N = 10,923), there was a single case of anaphylaxis reported with FLUARIX (<0.01%).
Children
In children aged 5 years through 17 years, the most common (≥10%) local and general adverse events were similar to those in adults but also included swelling at the injection site. In children aged 3 years through 4 years, the most common (≥10%) local and general adverse events included pain, redness, and swelling at the injection site, irritability, loss of appetite, and drowsiness.
A single-blind, active-controlled US trial evaluated subjects aged 6 months through 17 years who received FLUARIX (N = 2,081) or FLUZONE (N = 1,173), a US‑licensed trivalent, inactivated influenza vaccine (Sanofi Pasteur SA) (Trial 005). Children aged 6 months through 8 years with no history of influenza vaccination received 2 doses approximately 28 days apart. Children aged 6 months through 8 years with a history of influenza vaccination and children aged 9 years and older received 1 dose. Children aged 6 months through 35 months received 0.25 mL of FLUARIX or comparator influenza vaccine, and children aged 3 years and older received 0.5 mL of FLUARIX or comparator influenza vaccine.
Trial subjects were aged 6 months through 17 years and 49% were female; 68% were white, 18% were black, 3% were Asian, and 11% were of other racial/ethnic groups.
Solicited local and general adverse events were collected using diary cards for 4 days (day of vaccination and the next 3 days). Unsolicited adverse events that occurred within 28 days of vaccination (Day 0 to 27) after the first vaccination in all subjects and 21 days (Day 0 to 20) after the second vaccination in unprimed subjects were recorded using diary cards.
The frequencies of solicited adverse events for children aged 3 years through 4 years and for children aged 5 years through 17 years were similar for FLUARIX and the comparator vaccine (Table 4).

In children who received a second dose of FLUARIX or the comparator vaccine, the incidences of adverse events following the second dose were similar to those observed after the first dose.
Unsolicited adverse events that occurred in ≥1% of recipients of FLUARIX aged 6 months through 17 years included upper respiratory tract infection (5.5%), pyrexia (4.8%), cough (4.7%), vomiting (3.2%), headache (2.8%), rhinorrhea (2.7%), diarrhea (2.5%), pharyngolaryngeal pain (2.4%), nasopharyngitis (2.3%), otitis media (2.0%), nasal congestion (1.8%), upper abdominal pain (1.4%), and upper respiratory tract congestion (1.0%). The incidences of these events were similar in recipients of the comparator vaccine.
Worldwide voluntary reports of adverse events received for FLUARIX since market introduction of this vaccine are listed below. This list includes serious events or events which have causal connection to FLUARIX. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to the vaccine.

FLUARIX should not be mixed with any other vaccine in the same syringe or vial.
There are insufficient data to assess the concurrent administration of FLUARIX with other vaccines. When concomitant administration of other vaccines is required, the vaccines should be administered at different injection sites.
Pregnancy Category B. A reproductive and developmental toxicity study has been performed in female rats at a dose approximately 56 times the human dose (on a mg/kg basis) and revealed no evidence of impaired female fertility or harm to the fetus due to FLUARIX. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, FLUARIX should be given to a pregnant woman only if clearly needed.
In a reproductive and developmental toxicity study, the effect of FLUARIX on embryo-fetal and pre-weaning development was evaluated in pregnant rats. Animals were administered FLUARIX by intramuscular injection once prior to gestation, and during the period of organogenesis (gestation Days 6, 8, 11, and 15), 0.1 mL/rat/occasion (approximately 56-fold excess relative to the projected human dose on a body weight basis). No adverse effects on mating, female fertility, pregnancy, parturition, lactation parameters, and embryo-fetal or pre-weaning development were observed. There were no vaccine-related fetal malformations or other evidence of teratogenesis.
Pregnancy Registry
GlaxoSmithKline maintains a surveillance registry to collect data on pregnancy outcomes and newborn health status outcomes following vaccination with FLUARIX during pregnancy. Women who receive FLUARIX during pregnancy should be encouraged to contact GlaxoSmithKline directly or their healthcare provider should contact GlaxoSmithKline by calling 1-888-452-9622.
It is not known whether FLUARIX is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when FLUARIX is administered to a nursing woman.
The immune response to FLUARIX has been evaluated in children aged 6 months through 4 years. In a randomized, controlled trial, serum hemagglutination-inhibition (HI) antibody titers were lower in children aged 6 months through 35 months compared with a US-licensed vaccine. Based on these data, FLUARIX is not approved for use in children younger than 3 years. Immune responses in children aged 3 years through 4 years receiving FLUARIX or a US-licensed vaccine have been evaluated [see Clinical Studies (14.2)]. Safety has been evaluated in children aged 6 months through 17 years. The frequencies of solicited and unsolicited adverse events for children aged 3 years through 4 years and for children aged 5 years through 17 years were similar for FLUARIX and the comparator vaccine [see Adverse Reactions (6.1)].
A randomized, single-blind, active-controlled trial evaluated immunological non‑inferiority in a cohort of subjects aged 65 years and older who received FLUARIX (N = 606) or another US‑licensed trivalent, inactivated influenza vaccine (N = 604) (Sanofi Pasteur SA). In subjects receiving FLUARIX or the comparator vaccine, geometric mean antibody titers (GMTs) post-vaccination were lower in geriatric subjects than in younger subjects (aged 18 through 64 years). FLUARIX was non‑inferior to the comparator vaccine for each of the 3 influenza strains based on mean antibody titers and seroconversion rates. [See Clinical Studies (14.2).] Solicited local and general adverse events were similar for FLUARIX and the comparator vaccine among geriatric subjects (Table 3). For both vaccines, the frequency of solicited events in subjects aged 65 years and older was lower than in younger subjects (Table 3). [See Adverse Reactions (6.1).]
FLUARIX, Influenza Vaccine, for intramuscular injection, is a sterile colorless and slightly opalescent suspension. FLUARIX is a vaccine prepared from influenza viruses propagated in embryonated chicken eggs. Each of the influenza viruses is produced and purified separately. After harvesting the virus-containing fluids, each influenza virus is concentrated and purified by zonal centrifugation using a linear sucrose density gradient solution containing detergent to disrupt the viruses. Following dilution, the vaccine is further purified by diafiltration. Each influenza virus solution is inactivated by the consecutive effects of sodium deoxycholate and formaldehyde leading to the production of a “split virus.” Each split inactivated virus is then suspended in sodium phosphate-buffered isotonic sodium chloride solution. The vaccine is formulated from the 3 split inactivated virus solutions.
FLUARIX has been standardized according to USPHS requirements for the 2015‑2016 influenza season and is formulated to contain 45 micrograms (mcg) hemagglutinin (HA) per 0.5‑mL dose, in the recommended ratio of 15 mcg HA of each of the following 3 strains: A/Christchurch/16/2010 NIB‑74XP (H1N1) (an A/California/7/2009‑like virus), A/Switzerland/9715293/2013 NIB-88 (H3N2), and B/Phuket/3073/2013.
FLUARIX is formulated without preservatives. FLUARIX does not contain thimerosal. Each 0.5-mL dose also contains octoxynol-10 (TRITON® X-100) ≤0.085 mg, α-tocopheryl hydrogen succinate ≤0.1 mg, and polysorbate 80 (Tween 80) ≤0.415 mg. Each dose may also contain residual amounts of hydrocortisone ≤0.0016 mcg, gentamicin sulfate ≤0.15 mcg, ovalbumin ≤0.05 mcg, formaldehyde ≤5 mcg, and sodium deoxycholate ≤50 mcg from the manufacturing process.
The tip caps and plungers of the prefilled syringes of FLUARIX are not made with natural rubber latex.
Influenza illness and its complications follow infection with influenza viruses. Global surveillance of influenza identifies yearly antigenic variants. For example, since 1977, antigenic variants of influenza A (H1N1 and H3N2) viruses and influenza B viruses have been in global circulation.
Specific levels of hemagglutination-inhibition (HI) antibody titer post-vaccination with inactivated influenza virus vaccines have not been correlated with protection from influenza illness but the HI antibody titers have been used as a measure of vaccine activity. In some human challenge trials, HI antibody titers of ≥1:40 have been associated with protection from influenza illness in up to 50% of subjects.1,2 Antibody against one influenza virus type or subtype confers little or no protection against another virus. Furthermore, antibody to one antigenic variant of influenza virus might not protect against a new antigenic variant of the same type or subtype. Frequent development of antigenic variants through antigenic drift is the virological basis for seasonal epidemics and the reason for the usual incorporation of one or more new strains in each year’s influenza vaccine. Therefore, inactivated influenza vaccines are standardized to contain the hemagglutinins of strains (i.e., typically 2 type A and 1 type B), representing the influenza viruses likely to circulate in the United States in the upcoming winter.
Annual revaccination is recommended because immunity declines during the year after vaccination, and because circulating strains of influenza virus change from year to year.3
The efficacy of FLUARIX was evaluated in a randomized, double-blind, placebo-controlled trial conducted in 2 European countries during the 2006-2007 influenza season. Efficacy of FLUARIX, containing A/New Caledonia/20/1999 (H1N1), A/Wisconsin/67/2005 (H3N2), and B/Malaysia/2506/2004 influenza strains, was defined as the prevention of culture-confirmed influenza A and/or B cases, for vaccine antigenically matched strains, compared with placebo. Healthy subjects aged 18 through 64 years (mean: 39.9 years) were randomized (2:1) to receive FLUARIX (N = 5,103) or placebo (N = 2,549) and monitored for influenza-like illnesses (ILI) starting 2 weeks post-vaccination and lasting for approximately 7 months. In the overall population, 60% of subjects were female and 99.9% were white. Culture-confirmed influenza was assessed by active and passive surveillance of ILI. Influenza-like illness was defined as at least one general symptom (fever ≥100°F and/or myalgia) and at least one respiratory symptom (cough and/or sore throat). After an episode of ILI, nose and throat swab samples were collected for analysis; attack rates and vaccine efficacy were calculated (Table 5).

a NCT00363870.
b There were no vaccine matched culture-confirmed cases of A/New Caledonia/20/1999 (H1N1) or B/Malaysia/2506/2004 influenza strains with FLUARIX or placebo.
c Vaccine efficacy for FLUARIX exceeded a pre-defined threshold of 35% for the lower limit of the 2-sided 95% CI.
d Of the 22 additional cases, 18 were unmatched and 4 were untyped; 15 of the 22 cases were A (H3N2) (11 cases with FLUARIX and 4 cases with placebo).
In a post-hoc, exploratory analysis by age, vaccine efficacy (against culture-confirmed influenza A and/or B cases, for vaccine antigenically matched strains) in subjects aged 18 through 49 years was 73.4% (95% CI: 59.3, 82.8) [number of influenza cases: FLUARIX (n = 35/3,602) and placebo (n = 66/1,810)]. In subjects aged 50 through 64 years, vaccine efficacy was 13.8% (95% CI: ‑137.0, 66.3) [number of influenza cases: FLUARIX (n = 14/1,501) and placebo (n = 8/739)]. As the trial lacked statistical power to evaluate efficacy within age subgroups, the clinical significance of these results is unknown.
Adults
In a randomized, double-blind, placebo-controlled trial conducted in healthy subjects aged 18 through 64 years (mean: 39.1 years) in the United States, the immune responses to each of the antigens contained in FLUARIX were evaluated in sera obtained 21 days after administration of FLUARIX (N = 745) and were compared to those following administration of a placebo vaccine (N = 190). In the overall population, 54% of subjects were female and 80% were white. For each of the influenza antigens, the percentage of subjects who achieved seroconversion, defined as at least a 4‑fold increase in serum hemagglutination-inhibition (HI) titer over baseline to ≥1:40 following vaccination, and the percentage of subjects who achieved HI titers of ≥1:40 are presented in Table 6. The lower limit of the 2-sided 95% CI for the percentage of subjects who achieved seroconversion or an HI titer of ≥1:40 exceeded the pre-defined lower limits of 40% and 70%, respectively.

c Seroconversion defined as at least a 4-fold increase in serum titers of HI antibodies to ≥1:40.
Non-Inferiority Trial: In a randomized, single-blind, active-controlled US trial, immunological non-inferiority of FLUARIX (N = 923) was compared with FLUZONE (N = 922), a US‑licensed trivalent, inactivated influenza vaccine (Sanofi Pasteur SA). Subjects aged 18 through 64 years and 65 years and older were evaluated for immune responses to each of the vaccine antigens 21 days following vaccination [see Use in Specific Populations (8.5)]. In the overall population, 59% of subjects were female and 91% were white. The co-primary immunogenicity endpoints were GMTs of serum HI antibodies and the percentage of subjects who achieved seroconversion, defined as at least a 4-fold increase in serum HI titer over baseline to ≥1:40, following vaccination. The primary immunogenicity analyses were performed on the According-to-Protocol (ATP) cohort which included all eligible and evaluable subjects with results of at least one serological assay. For each of the influenza antigens, the GMTs and the percentage of subjects who achieved seroconversion are presented in Table 7. FLUARIX was non-inferior to the comparator influenza vaccine based on antibody GMTs (upper limit of the 2-sided 95% CI for the GMT ratio [comparator influenza vaccine/FLUARIX] ≤1.5) and seroconversion rates (upper limit of the 2-sided 95% CI on difference of the comparator influenza vaccine minus FLUARIX ≤10%).

Children
The immune response of FLUARIX was compared to FLUZONE, a US‑licensed trivalent, inactivated influenza vaccine (Sanofi Pasteur SA), in a single-blind, randomized trial in a subset of children aged 6 months through 4 years (Trial 005). The immune responses to each of the antigens contained in FLUARIX formulated for the 2006-2007 season were evaluated in sera obtained after 1 or 2 doses of FLUARIX (N = 426) and were compared to those following administration of the comparator influenza vaccine (N = 445). Further details on the clinical trial design and demographic information have been previously described [see Adverse Reactions (6.1)].
Non-inferiority of the immune response for FLUARIX to comparator influenza vaccine for subjects aged 6 months through 4 years was not demonstrated mainly due to lower antibody response to FLUARIX compared to the comparator influenza vaccine in subjects aged 6 months through 35 months. In subjects aged 3 years through 4 years, FLUARIX met at least one of the pre-specified criteria for demonstration of non-inferiority (GMT and seroconversion rate) for the influenza A strains but not for the influenza B strain. Seroconversion rates and the percentage of subjects with HI titers ≥1:40 were analyzed as secondary endpoints. In subjects aged 3 years through 4 years, the lower limit of the 95% Confidence Interval of the seroconversion rate for FLUARIX or the comparator influenza vaccine exceeded 40% for all 3 strains; also in this age group, the lower limit of the 95% Confidence Interval of the rate with HI titer ≥1:40 for FLUARIX or the comparator influenza vaccine exceeded 70% for both A strains (Table 8).
