About this trial

Infections are one of the key causes of newborn deaths. Among them, Group B Streptococcus (GBS) is the leading cause of sepsis and bacterial meningitis in the first 90 days of life.

Fortunately, GBS vaccines for pregnant women, a powerful tool for fighting infections, are currently in development. Once vaccine trials are completed, these vaccines can stop preventable newborn deaths.

The PReparing for Optimal Phase III/IV maTErnal Group B StreptococCal vaccine Trials in Africa (PROTECT) project, funded by the European \& Developing Countries Clinical Trials Partnership (EDCTP) and European Commission, is supporting medical sites in Kenya, Malawi, Mozambique, and Uganda to establish uniform pregnancy and infant health data collection processes. It is also establishing surveillance of GBS in newborns to determine incidence rates and measure the burden of disease. With better reporting systems, medical sites can participate in vaccine trials and monitor vaccine safety. At the same time, the consortium is working to understand the drivers of vaccine hesitancy and to develop culturally appropriate communication tools to facilitate engagement with vaccines.

The end goal is to set up a network of sites that can monitor vaccine safety for current and future vaccines.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Infants aged less than 90 days old with laboratory-confirmed GBS infection admitted at participating health facilities in Uganda, Malawi, Mozambique, and Kenya.

Infants whose parents or guardians provided written informed consent for their participation.

Residents in the catchment area of participating health facilities.

In Uganda, Kenya and Mozambique, pregnant women at any gestation period aged 18 years and above (reproductive age).

Disqualifiers

Pregnant women who are visiting/non-resident in the research area.

Those who may be unwell and unable to consent to take part in the study.

Trial population

WP2 Pregnancy Exposure Registries study population: Pregnant women and their infants up to hospital discharge at the chosen health facilities in Uganda, Malawi, Mozambique, and Kenya. WP3 GBS surveillance study population: All infants less than 90 days old admitted with GBS infection detected in blood or CSF by culture, or GBS detected in CSF by qPCR, at referral health facilities in the four countries during a period of at least 12 months. WP4 study population: All pregnant women attending the identified health facilities at the time of fieldwork and the health care workers who provide services to these women. It will also consist of stakeholders including, but not limited to, health workers from each country's Ministry of Health, head of facilities, community leaders (community gatekeepers and influencers), older women who give support in the community, male leaders, religious, political, administrative or cultural leaders.
