Hepatitis B study in Guinea-Bissau that was to be funded by CDC and that drew global backlash ‘will not move forward’

The US-backed hepatitis B vaccine trial in African newborns that drew global backlash was halted, the lead researcher said on Wednesday.

It was “now clear” that the study “will not move forward in Guinea-Bissau”, Frederik Schaltz-Buchholzer, a Danish researcher, wrote on LinkedIn, adding, “we were not given the necessary governmental approval.”

Guinea-Bissau has not approved the controversial hepatitis B study in newborns that would be funded by the US government and private partners, the African country’s minister of health said on Tuesday.

The study, which would not investigate the safety or effectiveness of vaccines but would instead track “nonspecific” health outcomes like overall mortality or neurodevelopmental conditions, has been championed by Robert F Kennedy Jr, secretary of the US Department of Health and Human Services (HHS) and a longtime anti-vaccine activist.
