Guinea-Bissau Vaccine Study Sparks Global Ethics Debate

A U.S.-funded study in Guinea-Bissau, investigating the health effects of hepatitis B vaccine dose timing on infants, has triggered significant ethical concerns. The $1.6 million grant awarded to Danish researchers by the U.S. Centers for Disease Control and Prevention is under scrutiny for its non-competitive nature.

Critics contend that randomizing infants to an "inferior" treatment, even if aligning with local norms, violates ethical research standards and risks undermining public trust in vaccines. This controversy occurs as the U.S. revises its own childhood immunization schedules, adding complexity to the debate.
