BISSAU, Guinea-bissau, January 22, 2026 09:17:00 – A new study in Guinea-Bissau is carefully tracking childhood vaccinations, but researchers emphasize that no child will receive fewer doses than they would through standard public health programs. It’s a delicate balance: gathering crucial data without disrupting essential healthcare access, adn it raises a familiar question – how do we best protect vulnerable populations while also learning from real-world conditions?
Vaccine Study Prioritizes Full Immunization Schedules
Researchers are monitoring vaccine efficacy in Guinea-Bissau, ensuring children receive all recommended doses.
- The study aims to gather data on vaccine effectiveness in a real-world setting.
- No child participating in the study will receive fewer vaccines than they would outside of it.
- Mothers known to be infected with hepatitis B will be offered vaccination.
- Many mothers in Guinea-Bissau are unaware of their hepatitis B status due to limited testing.
“No participating child receives fewer vaccines than they would outside the study,” stated Christine Stabell Bell, chair of the Bandim Health Project. This assurance is central to the ethical considerations of the research, which is unfolding in a region with meaningful healthcare challenges.
Hepatitis B and Maternal Screening
Vaccination against hepatitis B will be offered to mothers confirmed to be infected, explained Frederik Schaltz-Buchholzer, the lead investigator from Bandim. Tho, widespread testing gaps mean many mothers are unaware of their status, complicating preventative efforts.
