A Clinical Study to Assess the Safety of a New Influenza Vaccine

Inclusion Criteria

• Male or female, 18 through 49 years of age (not yet reached their 50th birthday) at the time of investigational product administration
• Healthy by medical history and physical examination
• Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act in the United States of America, European Union [EU] Data Privacy Directive in the EU) obtained from the subject/legal representative prior to performing any protocol-related procedures, including screening evaluations
• Female subjects of child-bearing potential, (ie, unless at least 2 years postmenopausal, surgically sterile [eg, bilateral tubal ligation, bilateral oophorectomy, or hysterectomy], has sterile male partner, or practices abstinence) must use an effective method of avoiding pregnancy (including oral, transdermal, or implanted contraceptives, intrauterine device, female condom with spermicide, diaphragm with spermicide, cervical cap, or use of a condom with spermicide by the sexual partner) for 30 days prior to administration of investigational product, and must agree to continue using such precautions for 60 days after investigational product administration. In addition, the subject must also have a negative urine or blood pregnancy test at screening and, if screening and Day 1 do not occur on the same day, on the day of vaccination prior to randomization.
• Males, unless surgically sterile must use an effective method of birth control with a female partner and must agree to continue using such contraceptive precautions for at least 30 days after dosing with investigational product (from Study Day 1 through Study Day 31)
• Subject available by telephone
• Ability to understand and comply with the requirements of the protocol, as judged by the investigator
• Ability to complete follow-up period of 180 days after dosing as required by the protocol

Exclusion Criteria

• History of hypersensitivity to any component of the vaccine, including egg or egg protein or serious, life threatening, or severe reactions to previous influenza vaccinations
• History of hypersensitivity to gentamicin
• Any condition for which the inactivated influenza vaccine is indicated, including chronic disorders of the pulmonary or cardiovascular systems (eg, asthma), chronic metabolic diseases (eg, diabetes mellitus), renal dysfunction, or hemoglobinopathies that required regular medical follow-up or hospitalization during the preceding year Note: A history of asthma that requires regular medical follow-up or hospitalization during the preceding 2 years is exclusionary. Investigator judgment is required to determine whether or not a subject has a history of asthma; however, for adult subjects, a remote history of wheezing or a remote diagnosis of asthma that the investigator does not consider to be relevant to current health does not need to be considered to be a history of asthma. For example, childhood asthma that has not required treatment in adulthood is not necessarily exclusionary
• Acute febrile (> 100.0°F oral or equivalent) and/or clinically significant respiratory illness (eg, cough or sore throat) within 14 days prior to randomization
• Any known immunosuppressive condition or immune deficiency disease, including human immunodeficiency virus (HIV) infection, or ongoing immunosuppressive therapy
• History of Guillain-Barré syndrome
• A household contact who is severely immunocompromised (eg, hematopoietic stem cell transplant recipient, during those periods in which the immunocompromised individual requires care in a protective environment); additionally, subject should avoid close contact with severely immunocompromised individuals for at least 21 days after receipt of investigational product
• Receipt of any investigational agent within 30 days prior to randomization, or expected receipt through 30 days after the dose of investigational product
• Receipt of any non-study vaccine within 30 days prior
