Eligibility | Inclusion Criteria: - Healthy women =18 and =49 years of age. - Participants who are willing and able to comply with scheduled visits, investigational plan, laboratory tests, lifestyle considerations, and other study procedures, including completion of the e-diary from Day 1 to Day 7 following administration of investigational product. - Healthy females at enrollment who are determined by medical history, physical examination, and clinical judgment of the investigator to be eligible for inclusion in the study. - Expected to be available for the duration of the study and who can be contacted by telephone during study participation. - Capable of giving personal signed informed consent. Exclusion Criteria: - Pregnant female participants; breastfeeding female participants; positive urine pregnancy test for women of childbearing potential (WOCBP) at Visit 1 (prior to vaccination) - History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis) to any component of the investigational product or any diphtheria toxoid-containing or CRM197-containing vaccine. - History of microbiologically proven invasive disease caused by group B streptococcus. - Immunocompromised participants with known or suspected immunodeficiency. - Bleeding diathesis or condition associated with prolonged bleeding that would in the opinion of the investigator contraindicate intramuscular injection. - Other acute or chronic medical or psychiatric condition, including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study. - Previous vaccination with any licensed or investigational GBS vaccine, or planned receipt during the participant's participation in the study (through the 1-month follow-up visit [Visit 2]). - Vaccination within 5 years with tetanus and diphtheria toxoids and acellular pertussis-containing vaccines (Tdap) before investigational product administration. - Participants who receive treatment with immunosuppressive therapy, including cytotoxic agents or systemic corticosteroids - Vaccination with diphtheria- or CRM197-containing vaccine(s) from 6 months before investigational product administration, or planned receipt through the 1-month follow-up visit. - Receipt or planned receipt of blood/plasma products or immunoglobulin, from 60 days before investigational product administration through the 1-month follow-up visit - Participation in other studies involving investigational drug(s) within 28 days prior to study entry and/or during study participation |
