The director-general of the World Health Organization said Wednesday that a U.S.-funded study of the hepatitis B vaccine in Guinea-Bissau would be “unethical” if it proceeds as planned.
“Of course, a sovereign country can decide whatever they want, but as far as WHO’s position is concerned, it’s unethical to proceed with this study,” Tedros Adhanom Ghebreyesus said during a WHO news conference.
