Controversial US study on hepatitis B vaccines in Africa is cancelled

AI Summary
A controversial US-funded study on hepatitis B vaccines in Guinea-Bissau has been cancelled, according to the Africa Centres for Disease Control and Prevention (CDC). The $1.6 million study, funded under the purview of Robert F Kennedy Jr., faced criticism for ethical concerns regarding the withholding of proven hepatitis B vaccines from newborns in a country with a high disease burden. The Africa CDC halted the study due to its problematic design and ethical issues. While officials in Guinea-Bissau expressed interest in continuing the trial, the Africa CDC stated it would only proceed if redesigned to meet ethical standards. The US Department of Health and Human Services (HHS) did not respond to requests for comment.
