Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: PHASE1/PHASE2
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~1. Male and female adults, 18 to 49 years of age, inclusive.~2. Healthy as judged by the Investigator or designee and determined by medical history, complete general history/symptom-directed physical examination, vital signs, screening laboratories, and medical history conducted no more than 30 days prior to study vaccine administration.~3. BMI of ≥18 and ≤32.~4. Comprehension of the study requirements, expressed availability for the required study period, and ability to attend scheduled visits.~5. Accessible by phone on a consistent basis.~6. Give his/her consent to participate in this study (by signing the ICF). In the opinion of the Investigator, competence and willingness to provide written, informed consent for participation after reading the informed consent form. The subject must have adequate opportunity to discuss the study with an Investigator or qualified designee.~7. If female, have a negative serum pregnancy test result prior to immunization.~8. Female of childbearing potential (except subjects in a same sex relationship), must use an effective birth control for the 28 days prior to immunization and must agree to continue employing adequate birth control measures for at least 60 days post-immunization and must have no plan to become pregnant for at least 60 days post-immunization. Highly effective birth control includes hormonal contraceptives (e.g., injectable, topical \[patch\], estrogenic vaginal ring, etc.), intra-uterine device (IUD), abstinence (confirmed by Investigator), or male condom plus spermicide. Abstinent subjects should be asked what method(s) they would use, should their circumstances change, and subjects without a well-defined plan should be excluded.~Exclusion Criteria:~1. Presence of significant acute or chronic, uncontrolled medical or neuropsychiatric illness. Uncontrolled is defined as:~   1. Requiring a new medical or surgical treatment within one month prior to study vaccine administration;~  2. Requiring a change in medication dosage in one month prior to study vaccine administration due to uncontrolled symptoms or drug toxicity (elective dosage adjustments in stable subjects are acceptable);~  3. Hospitalization or an event fulfilling the definition of a serious adverse event within one month prior to study vaccine administration.~2. Any medical or neuropsychiatric condition or any history of excessive alcohol use or drug abuse which, in the Investigator's opinion, would render the subject incompetent to provide informed consent or unable to provide valid safety observations and reporting.~3. Any confirmed or suspected immunosuppressive condition or immunodeficiency including history of human immunodeficiency virus (HIV) infection, Hepatitis B or C, or the presence of lymphoproliferative disease.~4. Presence of any febrile illness, oral temperature of \>38.0˚C within 24 hours prior to immunization. Such subjects may be re-evaluated for enrolment after resolution of illness.~5. History of autoimmune disease.~6. Administration of any vaccine (including any other influenza vaccine) within 30 days prior to study enrolment or planned administration within the period from the vaccination up to blood sampling at Day 21 or within 30 days prior to blood sampling at Day 201. Immunization on an emergency basis of a tetanus and diphtheria toxoids adsorbed for adult use (Td) will be allowed provided the vaccine is not administered within two weeks prior to study vaccine administration. Receipt of any other emergency immunizations (e.g., rabies) will result in a case-by-case review by the medical monitor of continued participation.~7. Administration of any adjuvanted or investigational influenza vaccine other than a 'simple' seasonal Trivalent influenza vaccine (TIV) or Quadrivalent influenza vaccine (QIV) within 1 year prior to study enrolment or planned administration prior to the end of this trial (Day 201).~8. Use of any investigational or non-registered product within 30 days prior to study enrolment or planned use during the study period. Subjects may not participate in any other investigational or marketed drug study while participating in this study.~9. Treatment with systemic glucocorticoids at a dose exceeding 10 mg of prednisone per day, or equivalent for more than 7 consecutive days or for 10 or more days in total, within one month of study vaccine administration, any other cytotoxic or immunosuppressant drug, or any globulin preparation within 3 months of vaccination. Low doses of nasal or inhaled glucocorticoids are allowed.~10. Use of high dose inhaled steroids or oral and parenteral high dose steroid medications. Nasal steroids are allowed.~11. Any significant disorder of coagulation or treatment with warfarin derivatives or heparin. Persons receiving prophylactic anti-platelet medications, e.g., low-dose aspirin \[≤ 325 mg/day (1 regular adult aspirin) or ≤ 81 mg/day (1 baby aspirin)\], and without a clinically apparent bleeding tendency are eligible.~12. History of allergy to any of the constituents of the quadrivalent VLP study vaccine, or to the Phosphate-buffered saline (PBS) (used as placebo).~13. History of severe allergic reactions (including anaphylaxis) to any food, medication or bee sting or previous severe asthma.~14. History of tobacco allergy.~15. Continuous use of anti-histamines in the last 4 weeks prior to immunization or use of anti-histamines 48 hours prior to study immunization.~16. Have a rash, dermatological condition, tattoos, or muscle mass at injection site which may interfere with injection site reaction rating.~17. Have received a blood transfusion within 90 days prior to study vaccination.~18. If female, either known pregnancy or urine beta-human chorionic gonadotropin (β-hCG) test results consistent with pregnancy during the screening period and prior to study vaccine administration on Day 0.~19. Female subjects who are lactating.~20. Any vital sign abnormalities: systolic blood pressure, diastolic blood pressure, resting heart rate not well controlled or according to the Investigator's opinion.~21. Cancer or treatment for cancer within 3 years of study vaccine administration. Persons with a history of cancer who are disease-free without treatment for 3 years or more are eligible. Persons with treated and uncomplicated basal cell carcinoma of the skin are eligible.
