Extension Study to Evaluate the Immunogenicity and Safety of the Second Dose of GBS Trivalent Vaccine in Healthy Non-Pregnant Subjects.

Percentage of subjects who reach pre-defined sequential serotype-specific serum antibody levels for serotype Ia at Day 61 post-vaccination, as measured by Enzyme-linked immunosorbent Assay (ELISA).

Percentage of subjects who reach pre-defined sequential serotype-specific serum antibody levels for serotype Ib at day 61 post-vaccination. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

Percentage of subjects who reach pre-defined sequential serotype-specific serum antibody levels for serotype III at day 61 post-vaccination. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

Threshold for Erythema, Swelling and Induration: None (0 mm), Any (>= 1 mm).

The number of subjects with any unsolicited AEs from the day of vaccination in study V98_06E1 to Day 31. An unsolicited adverse event is an adverse event that was not solicited using a Subject Diary and that was spontaneously communicated by a subject who has signed the informed consent. Potential unsolicited AEs may be medically attended (defined as symptoms or illnesses requiring hospitalization, or emergency room visit, or visit to/by a health care provider), or were of concern to the subject. Possibly Related AE definition: the administration of the investigational vaccine and AE are considered reasonably related in time and the AE could be explained by exposure to the investigational vaccine or by other causes. Probably Related AE definition: exposure to the investigational vaccine and AE are reasonably related in time and no alternative explanation has been identified.

An SAE is defined as any untoward medical occurrence that at any dose results in one or more of the following: Death; life-threatening; that does not refer to an event which hypothetically might have caused death if it were more severe; required or prolonged hospitalization; persistent or significant disability/incapacity; congenital anomaly/or birth defect; any important and significant medical event that may not be immediately life-threatening or resulting in death or hospitalization but, based upon appropriate medical judgement, may jeopardize the subject or may require intervention to prevent one of the other outcomes listed above. "Medically attended adverse event" is defined as an adverse event that leads to a visit to a healthcare provider and "AEs leading to withdrawal" are defined as adverse events leading to study or vaccine withdrawal.

Percentage of subjects who reach pre-defined sequential serotype-specific serum antibody levels for serotype Ia at Day 31 post-vaccination, as measured by ELISA.

Percentage of subjects who reach pre-defined sequential serotype-specific serum antibody levels for serotype Ib at day 31 post-vaccination. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

Percentage of subjects who reach pre-defined sequential serotype-specific serum antibody levels for serotype III at day 31 post-vaccination. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

The Geometric Mean ELISA Antibody Concentrations of GBS Serotype Ia in All Subjects were estimated for at Day 1, Day 31 and Day 61.

The Geometric Mean Antibody Concentrations of GBS Serotype Ib in All Subjects were estimated for at Day 1, Day 31 and Day 61. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

The Geometric Mean Antibody Concentrations of GBS Serotype III in All Subjects were estimated for at Day 1, Day 31 and Day 61. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

The Geometric Mean ELISA Antibody Concentrations of GBS Serotype Ia in subjects with prevaccination serotype-specific GBS antibody less than LLQ were estimated for at Day 1, Day 31 and Day 61.

The Geometric Mean Antibody Concentrations of GBS Serotype Ib in subjects with prevaccination serotype-specific GBS antibody less than LLQ were estimated for at Day 1, Day 31 and Day 61. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

The Geometric Mean Antibody Concentrations of GBS Serotype III in subjects with prevaccination serotype-specific GBS antibody less than LLQ were estimated for at Day 1, Day 31 and Day 61. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

The Geometric Mean ELISA Antibody Concentrations of GBS Serotype Ia in subjects with prevaccination serotype-specific GBS antibody equal or greater than LLQ were estimated for at Day 1, Day 31 and Day 61.

The Geometric Mean Antibody Concentrations of GBS Serotype Ib in subjects with prevaccination serotype-specific GBS antibody equal or greater than LLQ were estimated for at Day 1, Day 31 and Day 61. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

The Geometric Mean Antibody Concentrations of GBS Serotype III in subjects with prevaccination serotype-specific GBS antibody equal or greater than LLQ were estimated for at Day 1, Day 31 and Day 61. As the singleton ELISA was no longer in use at the time of serotypes Ib and III testing, results for both serotypes were tested using multiplex immunoassay.

Geometric Mean ELISA Anti-Diphtheria Antibody Concentrations (95%CI) in All Subjects at Day 1 Pre-vaccination in the V98_06 study or V98_06E1 for the Naive Group and at Day 61 Post-vaccination in Study V98_06E1. Anti-diphtheria antibody testing was not performed in this study because no diphtheria vaccine was administered in the study and also because data from other Cross Reactive Material(CRM)-based vaccines demonstrate that administration has not resulted in a decline in anti-diphtheria antibody concentrations.
