Guinea vaccine trial suspended over ethics

By Newz.Africa Health Desk | Bissau, Guinea-Bissau | 30 January 2026 | Guinea vaccine

Guinea-Bissau has suspended a US-funded hepatitis B vaccine study. The health minister said the trial lacked proper ethical review. The move has drawn attention to sovereignty in global health research and the protection of vulnerable populations.

Guinea vaccine study halted by minister

The health minister, appointed earlier this month, announced the suspension on 25 January. According to the ministry statement, the trial design failed to meet national ethical standards. The study, led by Danish researchers, planned to withhold hepatitis B vaccines from some newborns.

Ethics questioned by experts

African health experts criticised the design. They said withholding vaccines in a country with high hepatitis B prevalence was unacceptable. Per WHO data, hepatitis B affects more than 8% of the population in West Africa. The Guinea-Bissau Medical Association added that ethical oversight must be strengthened to protect infants.

Trial starts sovereignty debate

The suspension has raised wider questions about who sets research agendas in lower-income countries. Local leaders argue studies must align with community needs. According to the African Union health commission, national review boards should have final authority. The future of the trial now depends on a sovereign review process.
