Approximately 600 participants will be randomized to receive a single dose of low, mid, or high concentration of IVT GBS-06, or a placebo (saline control) at Day (D)1, administered IM by injecting 0.5 mL into the deltoid muscle. The three dose levels denote the amount of capsular polysaccharide (CPS) for each of the six serotypes per 0.5 mL. These four study groups will be enrolled simultaneously to allow for parallel assessments of overall IVT GBS-06 safety and tolerability. Participants will be randomized in a 1:1:1:1 ratio to one of the dose levels or placebo. This study will utilize a sentinel-cohort design in which 20 participants overall (i.e., N=5 per treatment arm) at the US site will be randomized, vaccinated, and evaluated for safety prior to opening enrolment of additional participants in USA and in South Africa. This study targets representation from both study populations and therefore at least 220 participants will be recruited from each of the two sites and will allow competitive enrollment across the two study sites for the remaining 160 participants to reach 600 within target enrollment period."}, "eligibilityModule"=>{"sex"=>"FEMALE", "stdAges"=>["ADULT"], "maximumAge"=>"49 years", "minimumAge"=>"18 years", "genderBased"=>true, "genderDescription"=>"Women between the ages of 18 to 49.", "healthyVolunteers"=>true, "eligibilityCriteria"=>"Inclusion Criteria:\n\n1.
