Guinea-Bissau has suspended a U.S.-funded hepatitis B vaccine study, citing ethical concerns and insufficient scientific review, despite pushback from U.S. health officials. The controversial study, led by Danish researchers, has ignited debate about ethical research practices in developing nations, particularly in light of recent changes to the U.S. vaccination schedule, prompting international collaboration to review the trial's merits. This decision comes amidst political instability in Guinea-Bissau, highlighting the complexities of conducting medical research in countries with fragile governance.
