Brief Summary
The purpose of this study is to evaluate the safety of a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, compared to the safety of a similar, licensed meningococcal A/C/Y/W-135-DT conjugate vaccine. The investigators will also evaluate the production of antibodies to of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine, as a measure of vaccine effectiveness.

Interventions
NmVac4-A/C/Y/W-135-DT™conjugate is a vaccine in liquid form composed of purified polysaccharides (PS) conjugated to diphtheria toxoid. Single intramuscular 0.5 mL dose contains 4 µg each Serogroup A, C, W-135, Y PS conjugated to approximately 16 µg total diphtheria toxoid.
Eligibility Criteria
You may qualify if:
- Willing and able to give informed consent and comply with all aspects of the evaluation after the nature of the study is explain
- For the purpose of this study, a healthy volunteer is defined as healthy male or female, with no significant chronic conditions
- Age 18 to 50 years old
- Either gender. Abstinence or use of contraception during the eight weeks after vaccination will be required for non menopausal (\< two years post-menopause) or non surgically sterile women
- Persons with antibody titer(s) of \<2 µg/mL to serogroup(s) A, C, Y, or W-135 polysaccharides as measured by ELISA
You may not qualify if:
- Age less than 18 years or over 50 years.
- History of Guillain-Barré syndrome (GBS).
- Pregnancy or lactation.
- History of meningococcal meningitis.
- History of invasive (clinical or laboratory diagnosis) meningococcal disease.
- History of meningococcal meningitis vaccination.
- Screening laboratory abnormalities (in the opinion of the Investigator) that would raise safety concerns for participation in the study.
- Use of immunosuppressive drugs within 30 days prior to study enrollment, not including topical or inhaled steroids/cytotoxic agents.
- History of anaphylactic shock, asthma, urticaria, or other allergic or hypersensitivity reactions following vaccination.
- History of severe allergic disorders or autoimmune connective tissue disorders, including rheumatoid arthritis. A high sensitivity C-Reactive Protein (CRP) test at screening will be used as part of the assessment of autoimmune disorders by the Principal Investigator.
- Use of systemic antibiotics within 72 hours prior to study enrollment.
- History of cirrhosis.
- Positive results of testing for HepBsAg, Hepatitis C or HIV-1 or HIV-2 antibodies.
- Positive results of drug screen (amphetamine, THC, cocaine).
- Persons with antibody titer(s) of \>2 µg/mL to serogroup (s) A, C, Y, or W 135 as measured by ELISA.
