Why Guinea-Bissau halted a controversial hepatitis vaccine trial for babies
Guinea-Bissau has halted a controversial US-funded hepatitis B vaccine trial that experts said would have withheld lifesaving shots from thousands of infants. The project, led by the Bissau-based Bandim Health Project, failed to secure necessary government approval, and police raided its facilities in October, seizing vaccine batches. Authorities are still investigating whether the trial met the country's safety standards.
