一项由丹麦研究人员主导的肝炎B疫苗试验已在几内亚比绍获得批准，该项目因得到美国卫生部长肯尼迪的支持而备受关注。1丹麦南部大学伦理委员会本周投票通过了该试验，计划在几内亚比绍招募14000名新生儿参与，其中一半将在出生时接种疫苗，另一半则延迟6周后接种。1几内亚比绍卫生部长昆欣·南托特表示该项目此前在国际抗议后被暂停，现已获得通过。1
这项试验的伦理问题引发了广泛争议。1丹麦伦理委员会评审员斯蒂格·博尔森·汉森于周五因伦理问题辞职抗议。1美国疾病控制与预防中心已在本年度预算中为该项目拨款160万美元。1专家保罗·奥菲特指出，肯尼迪无法在美国进行此试验，因为存在重大伦理问题。1几内亚比绍约18%的成人携带肝炎B病毒，原计划2027年开始为全部新生儿接种肝炎B疫苗，已推迟至2028年。1
A disputed hepatitis B vaccine trial led by Danish researchers and supported by U.S. Health Secretary Robert F. Kennedy Jr. has received approval to proceed in Guinea-Bissau.1 The University of Southern Denmark's ethics committee voted this week to authorize the study, which will enroll approximately 14,000 newborns, with half receiving the vaccine at birth and the other half receiving it six weeks later.1
Guinea-Bissau's health minister, Quintin Nantoto, confirmed that the project had previously been suspended following international protests but has now been cleared to move forward.1 The country currently plans to begin vaccinating all newborns against hepatitis B in 2028, delayed from an original target of 2027.1 Approximately 18 percent of Guinea-Bissau's adult population carries the hepatitis B virus.1
The trial has sparked significant ethical concerns. A member of the Danish ethics committee, Stig Bolsen Hansen, resigned on Friday in protest over ethics issues surrounding the study.1 Paul Offit, a prominent vaccine expert, stated that Kennedy would be unable to conduct such a trial in the United States because it presents substantial ethical problems.1 The U.S. Centers for Disease Control and Prevention has allocated $1.6 million in funding for the project in its current budget.1
