Meningococcal disease is caused by a germ. There are many different types of this germ. The Meningococcal germ can cause diseases such as infection of the brain lining (Meningitis). The likelihood of experiencing Meningococcal disease for any individual is low; however, adolescents and young adults have an increased risk of disease compared to older people. This study is being done with healthy adolescents and young adults to see if an investigational vaccine might help the body make antibodies and fight off different germs that cause meningococcal disease.
