Eligibility Criteria

Age17 Years - 35 Years
Sexmale
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Active duty, male subject, 17-35 years of age, inclusive, at the time of screening.

  • Free of known significant health problems as established by the requirements to be enrolled in a military training program before entering into the study.
  • Agrees to be reachable by phone, email or letter at 6 months post-vaccination.

You may not qualify if:

  • Presence of clinically significant SSTI (e.g., cellulitis, abscess) at screening or other skin or skin structure infections that would confound the interpretation of clinical response.
  • Reports a history of allergic response(s), anaphylaxis, or other serious reactions to previous vaccinations.
  • Reports a history of allergies to yeast
  • Reports a history of anaphylaxis or other serious reactions to aluminum.
  • Reports a history of autoimmune disease (psoriasis, etc.)
  • Seropositive for HIV antibody.
  • Reports the use of any immunosuppressive drugs, including systemic corticosteroids (more than 14 days at a dose of \>20 mg/day prednisone or equivalent), within 4 weeks prior to dosing.
  • Reports receiving any blood products within 3 months prior to dosing.
  • Reports donating blood/plasma within 28 days prior to dosing.
  • Illness causing temperature ≥ 100.4°F
  • Evidence of abnormal, unresolved laboratory results in the subject's medical record for the following tests: hemoglobin, white blood cell count, platelet count, creatinine, and alanine aminotransferase
  • Any other medical and/or social reason which, in the opinion of the investigator(s), would increase the subject's risk of having an adverse reaction as a result of participation in the study.
