- 摘要
- 美国于1月退出联合国卫生机构
- 世卫组织还称美国资助的乙肝疫苗研究不道德
- 几内亚比绍计划中的研究颇具争议
2月11日（路透社）- 世卫组织官员在周三的新闻发布会上表示，美国将参与本月底召开的世界卫生组织会议，以确定即将推出的流感疫苗成分。
华盛顿在一年的警告声中于1月正式退出世卫组织，此前有警告称此举将损害美国乃至全球的公共卫生，该国称其决定反映了联合国卫生机构在新冠疫情管理中的失败。

美国退出后，该国将与世卫组织开展多少合作一直不明朗，而流感疫苗方面的合作是持续联系的一个迹象。
世卫组织流行病和大流行防范主任玛丽亚·范克尔霍夫（Maria Van Kerkhove）表示，全球流感监测和应对网络——一个由130个国家的150多个实验室组成的系统——在追踪季节性和人畜共患流感病毒以及每六个月更新疫苗建议方面发挥着核心作用。
共有七个合作中心，包括美国、英国和澳大利亚的机构。
范克尔霍夫说，由于资金问题，全球流感病毒样本的传播量出现了”轻微下降”，但目前运输已恢复。
几内亚比绍疫苗研究”不道德”——谭德塞
在同一场新闻发布会上，世卫组织总干事谭德塞·阿达诺姆·格布雷耶苏斯（Tedros Adhanom Ghebreyesus）表示，美国资助的在几内亚比绍开展的乙肝疫苗对新生儿影响研究计划备受批评，是不道德的。
“就世卫组织的立场而言，继续这项研究是不道德的，”谭德塞说，但补充说这最终是一个国内决定。
非洲卫生官员1月表示，该研究尚未取消，但将接受进一步的伦理审查。
科学家们反对这项研究，因为在乙肝高发的国家，参与研究的一些新生儿不会获得已知安全且能挽救生命的疫苗。这种疾病在分娩时常由母亲传给孩子，可能导致肝衰竭和癌症。
研究人员称该项目符合伦理，因为几内亚比绍目前不提供出生时接种乙肝疫苗，第一剂在六周时接种。
该研究旨在调查疫苗的潜在”非特异性影响”，包括皮肤疾病和神经发育障碍，如自闭症。

- Summary
- US quit the UN health agency in January
- WHO also calls US-funded hepatitis B vaccine study unethical
- The planned study in Guinea-Bissau has been controversial
Feb 11 (Reuters) – The United States will take part in a World Health Organization meeting at the end of the month to determine the composition of upcoming influenza vaccines, the agency’s official said at a press conference on Wednesday.
Washington officially left the WHO in January after a year of warnings that doing so would hurt public health in the U.S. and globally, saying its decision reflected failures in the U.N. health agency’s management of the COVID-19 pandemic.

It has been unclear how much the country would work with the WHO following the departure, and the collaboration on flu vaccines is a sign of an ongoing link.
Maria Van Kerkhove, the WHO’s director for epidemic and pandemic preparedness, said the global influenza surveillance and response network — a system of more than 150 laboratories across 130 countries — plays a central role in tracking seasonal and zoonotic influenza viruses and updates vaccine recommendations every six months.
There are seven collaborating centers, including facilities in the U.S., the UK and Australia.
Van Kerkhove said there had also been “a slight dip” in the global circulation of influenza virus samples after funding challenges, but shipments had now resumed.
GUINEA-BISSAU VACCINE STUDY ‘UNETHICAL’ – TEDROS
At the same press conference, WHO Director General Tedros Adhanom Ghebreyesus said a planned U.S.-funded research in Guinea-Bissau to study the effects of hepatitis B vaccines on newborns, which has drawn significant criticism, is unethical.
“As far as WHO’s position is concerned, it’s unethical to proceed with this study,” Tedros said, but added that it was ultimately a domestic decision.
African health officials in January said the study has not been canceled, but will undergo further ethical review.
Scientists have opposed the study because some of the newborns involved would not get the vaccine, which is known to be safe and save lives, in a country with high rates of hepatitis B. The disease transmits commonly from mother to child during birth and can cause liver failure and cancer.
The study’s researchers say the project is ethical because the vaccine is not yet administered at birth in Guinea-Bissau, where the first dose is given at six weeks.
The research was due to investigate potential “non-specific effects” of the vaccine, including skin disorders and neuro-developmental disorders, such as autism.
