Guinea-Bissau Halts US-Funded Infant Vaccine Study

A planned US-funded vaccine trial involving 14,000 newborns in Guinea-Bissau was suspended last month due to significant public and expert outrage over its ethical implications. Danish researchers intended to compare the health outcomes of babies receiving the hepatitis B vaccine at birth versus six weeks later over five years.

Concerns were voiced by international health experts and former Guinea-Bissau health minister Magda Robalo, who stated the study was unethical for withholding a known effective intervention from infants. The national public health institute was reportedly not fully informed, raising questions about regulatory oversight.
