Controversial US-funded Hepatitis B vaccine study cancelled due to ethics concerns.
A highly contentious $1.6m US-funded study on administering hepatitis B vaccines to newborns in Guinea-Bissau has been abruptly halted, according to senior officials at the Africa Centres for Disease Control and Prevention (CDC). The study, backed by Robert F Kennedy Jr, a prominent vaccine skeptic, had drawn widespread criticism over its questionable methodology.
In a statement made during a press conference on Thursday morning, Yap Boum, a senior official at the CDC, confirmed that the trial was cancelled due to concerns about the ethics of the design. "The way the study was designed was a big challenge," Boum stated, adding that the Africa CDC would only proceed with the trial if it was redesigned to address these issues.
Guinea-Bissau officials initially claimed that the trial would still move forward but maintained that the redesign would be crucial in ensuring the study's ethics. The original plan had involved withholding vaccines from 7,000 newborns and administering them to another 7,000 at random, raising significant concerns about depriving some children of vital protection against a potentially deadly disease.
Critics argue that such an approach would put children's lives at risk, with experts likening the trial to infamous medical experiments in the past. Paul Offit, an infectious diseases physician, described it as "a very damaging study" that could have long-lasting consequences.
A study by Emory University's Boghuma Titanji found no evidence to support the claim that adding multiple vaccines would interfere with their effects. However, she did emphasize the importance of designing trials led by African scientists and powered by questions from Africans, rather than exploiting scarce vaccine resources.
The cancellation has been hailed as a victory for advocacy groups pushing back against unethical research practices in Africa.
