Summary
This is a Phase I, randomized, double blinded, clinical trial in up to 240 males and non-pregnant females, 18-45 years of age, inclusive, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety, reactogenicity and immunogenicity of either the 2018/2019 seasonal Fluzone or Flublok Quadrivalent Influenza Vaccine (QIV) manufactured by Sanofi Pasteur (SP) given without adjuvant or with one of two adjuvant formulations, AF03 or Advax-CpG55.2. Eight Vaccine and Treatment Evaluation Unit (VTEU) sites will be included in the study. Study duration is approximately 18 months, and subject participation duration is 12 months. The primary objectives of this study are: 1) to assess the safety and reactogenicity of 2018/2019 Fluzone and Flublok with and without AF03 or Advax-CpG55.2 adjuvant; 2) to assess the serum hemagglutination inhibition (HAI) antibody responses against 2018/2019 QIV strains from baseline (Day 1) to approximately Day 29 after receipt of 2018/2019 Fluzone and Flublok with and without AF03 or Advax-CpG55.2 adjuvant; 3) to assess the serum neuraminidase inhibition antibody (NAI) responses by enzyme-linked lectin assay (ELLA) against NA antigens in the 2018/2019 QIV from baseline (Day 1) to approximately Day 29 after receipt of 2018/2019 Fluzone and Flublok with and without AF03 or Advax-CpG55.2 adjuvant; 4) to assess the influenza neutralizing (Neut) antibody titer responses against 2018/2019 QIV strains from baseline (Day 1) to approximately Day 29 after receipt of 2018/2019 Fluzone and Flublok with and without AF03 or Advax- CpG55.2 adjuvant.Phase:

2. Are able to understand and comply with planned study procedures and be available for
all study visits.
3. Must agree to the collection of venous blood per protocol.
4. Are males or non-pregnant females, 18 to 45 years of age, inclusive at time of
enrollment.
5. Are in good health*. *As determined by medical history and physical examination to
evaluate acute or currently ongoing chronic medical or psychiatric diagnoses or
conditions, defined as those that have been present for at least 90 days, which would
affect the assessment of the safety of subjects or the immunogenicity of study
vaccinations. Chronic medical diagnoses or conditions should be stable for the last 60
days (no hospitalizations, emergency room or urgent care for condition, or invasive
medical procedure and no adverse symptoms that need medical intervention such as
medication change/supplemental oxygen). This includes no change in chronic
prescription medication, dose or in the 60 days prior to enrollment. Any prescription
change that is due to change of health care provider, insurance company, etc., or that
is done for financial reasons, as long as in the same class of medication, will not be
considered a deviation of this inclusion criterion. Subjects may be on chronic or as
needed (prn) medications if, in the opinion of the site PI or appropriate
sub-investigator, they pose no additional risk to subject safety or assessment of
reactogenicity and immunogenicity and do not indicate a worsening or treatment of
continued symptoms of medical diagnosis or condition. Note: Low dose topical,
corticosteroids as outlined in the Subject Exclusion Criteria as well as herbals,
vitamins and supplements are permitted.

U/L; amylase (Total) 35-121 U/L, for subjects to qualify for randomization and
vaccination.
11. Women of childbearing potential* must use an acceptable contraception method** from at
least 30 days before the first study vaccination until 60 days after the second study
vaccination.
