MMGH supported the WHO Initiative for Vaccine Research (IVR) in preparing a report on the considerations for operationalising group B streptococcal (GBS) maternal vaccination as part of a Public Health Value Proposition for GBS vaccines. The report was developed on the basis of an extensive literature review and an online survey gathering information on global and country stakeholder perceptions on GBS disease, its public health importance, and the prioritisation of GBS vaccination as a means to reduce its impact.
