Group B Strep Clinical Trial

Despite preventive measures, group B strep infection continues to threaten the health of infants around the world. Your participation in a new research study could help us find a vaccine.

Group B strep (GBS) is a bacterium that causes a variety of infections, especially in pregnant women and infants. Although GBS infections may be relatively minor in adults, GBS can cause more serious illness in infants, including sepsis, meningitis, pneumonia, and death. This study is evaluating if an investigational GBS vaccine is safe, and if it can help produce antibodies in pregnant women and their infants which would help them fight the infection and prevention of GBS disease.
