Brief summary

The study is a prospective single site exploratory study to examine the impact of Food and Drug Administration (FDA) approved seasonal flu vaccine on the immune responses of H5N1 vaccine previously received with or without the AS03 adjuvant.

Detailed description

Influenza, caused by the influenza virus, is a contagious respiratory disease that can result in mild to severe illness. It is estimated that up to 80,000 deaths and approximately 200,000 Americans are hospitalized annually due to complications. Vaccination is the most effective way of controlling flu and preventing its illness and complications; however, antibody responses to seasonal influenza vaccines decrease over time and only target a small number of antibody binding sites In 2015, the Hope Clinic of the Emory Vaccine Center completed a study analyzing human immune responses to a pandemic H5N1, or bird flu vaccine, either alone or combined with the GlaxoSmithKline adjuvant system 03 (AS03). Participants that took part in the 2013 HIPCVAX-010 Systems Biology of Influenza A (H5N1) Virus Monovalent Vaccine with and without AS03 Adjuvant study will be enrolled in this study to assess the effect of seasonal influenza vaccine in shaping the immune responses. The study aims to address important immunological mechanisms that can assist scientists in the creation of a universal influenza vaccine.

Inclusion criteria

* Participated in HIPCVAX-010 Systems Biology of Influenza A (H5N1) Virus Monovalent Vaccine with and without AS03 Adjuvant study. * Capable of informed consent and provision of written informed consent before any study procedures. * Capable of attending all study visits according to the study schedule. * Are in good health, as determined by medical history and targeted physical exam related to this history. * Female subjects of childbearing age must have a negative urine pregnancy test before study vaccination, and must use at least one form of contraception to avoid pregnancy for 28 days before and 28 days after Fluarix Quadrivalent administration.

Number of Participants With a Four-fold Increase in Stem-specific Antibody Titers (H5, Hemagglutinin Antibody) Against H5N1 at Day 29 After Vaccination With the Seasonal Influenza Vaccine Among All the Participants in Both ArmsBaseline (Day 1) before vaccination and Day 29 post vaccinationAntibody Titers (hemagglutinin inhibition antibody titers) are measured through immunologic assays from blood draw at Baseline (Day1) before study vaccination and are repeated on Day 29. Participants with four fold increase in titer levels will be recorded.

Number of Solicited (AE's) Grade 2 and Above at Day 8 After Vaccination With the Seasonal Influenza Vaccine Among the Participants in Both Armsup to Day 8 post vaccinationTo evaluate safety, grade 2 and above solicited AE's are recorded from Day 1 post vaccination to Day 8 post vaccination.Solicited adverse events include local (pain, erythema and induration) and systemic (chills, loss of appetite, headache, fatigue, myalgia, arthralgia, nausea, fever (body temperature ≥ 38°C (100.4°F)).
Number of Unsolicited Adverse Events (AE's) Grade 2 and Above at Day 29 After Vaccination With the Seasonal Influenza Vaccine Among the Participants in Both ArmsUp to Day 29 post vaccinationTo evaluate safety, grade 2 and above unsolicited AE's are recorded from Day 1 post vaccination to Day 29 post vaccination. Unsolicited AE information is volunteered or noted in an unsolicited manner and not as a required data element through a case report form.
Number of Serious Adverse Events at Day 365 Among the Participants in Both ArmsUp to 365 days post vaccinationSerious adverse events are recorded from Day 1 post vaccination to Day 365 post vaccination. A serious adverse event is any adverse event that results in death, is life threatening, results in a persistent or significant disability/incapacity, results in hospitalization or prolongs an existing hospitalization, is a congenital anomaly/birth defect, or is considered an other important medical event based on medical judgement.
