- 内容摘要
- 特朗普的行政令要求将儿童疫苗接种计划缩减至11剂
- 世卫组织表示，疫苗接种时间安排是基于对疾病风险和免疫系统发育的全面评估
- 医生警告称，减少疫苗推荐接种数量可能会提升疾病感染风险，并让家长感到困惑
日内瓦8月11日电（路透社）——美国总统唐纳德·特朗普签署行政令，要求减少美国推荐的儿童疫苗接种数量后，世界卫生组织于周二为制定儿童免疫接种计划的科学流程进行了辩护。
周一，特朗普签署行政令，呼吁将儿童疫苗接种计划缩减至11剂。特朗普称，此举将为美国儿童提供“黄金标准”的保护，并让美国与其他推荐接种疫苗更少的发达国家保持一致。

疫苗专家表示，其他推荐接种疫苗更少的发达国家面临的疾病风险各不相同，医疗体系也存在差异。
这项行政令推进了美国卫生与公众服务部部长小罗伯特·F·肯尼迪长期以来的目标，他曾质疑疫苗安全性，并宣扬疫苗与自闭症存在关联的言论，尽管科学研究和公共卫生机构均未发现两者存在关联的证据。
世卫组织发言人塔里克·亚萨雷维奇在日内瓦的新闻发布会上表示，疫苗接种建议基于世卫组织、各国当局和独立专家团体60多年的研究成果。
亚萨雷维奇在日内瓦对记者表示，各类疫苗的接种时间是通过广泛的科学评估确定的，评估内容包括人群在何时最易感染特定疾病，以及免疫系统的发育阶段。
亚萨雷维奇表示，各国通常依靠由多学科专家组成的国家免疫技术咨询小组，为政府和疫苗项目管理者提供独立的、基于证据的建议。他说，这些小组在制定国家免疫计划时，会参考世卫组织免疫战略咨询专家组（SAGE）的指导意见。
“世卫组织出台的标准均基于科学依据，”亚萨雷维奇说道。
“我们希望所有国家都能运用我们现有的最佳科学证据。”
麻疹、腮腺炎、风疹疫苗拆分接种
特朗普的行政令遭到了医学协会、公共卫生专家和疫苗制造商的批评，他们称没有新的科学证据支持此次调整，现行的美国疫苗接种计划反映了数十年来的研究成果以及美国人的具体健康需求，并驳斥了与其他国家进行比较的说法。

医生们警告称，减少推荐接种的疫苗数量可能会让更多儿童面临可预防疾病的感染风险，并让家长在儿童何时应接种疫苗的问题上产生困惑。
特朗普的行政令还建议将麻疹、腮腺炎、风疹联合疫苗（MMR）拆分为三剂单独注射。疫苗制造商默克公司表示，尚无已发表的科学证据证明拆分疫苗接种具有益处，并警告称，要求分多次就诊可能会增加疫苗接种延迟或遗漏的风险。

- Summary
- Trump’s order calls for childhood schedule of 11 vaccinations
- WHO says vaccine timing reflects extensive review of disease risk and immune system development
- Doctors warn fewer recommendations could raise disease risk and confuse parents
GENEVA, Aug 11 (Reuters) – The World Health Organization on Tuesday defended the science-based process used to determine childhood immunisation schedules after U.S. President Donald Trump signed an executive order aimed at reducing the number of recommended childhood vaccinations in the United States.
On Monday, Trump signed an executive order calling for a reduced childhood vaccination schedule of 11 immunisations. Trump said the move would provide U.S. children with “gold-standard” protection and align the United States more closely with other developed countries that recommend fewer shots.

Vaccine experts say that other developed countries that may recommend fewer shots face different disease risks and have different healthcare systems.
The order advances a long-standing objective of U.S. Health Secretary Robert F. Kennedy Jr., who has questioned vaccine safety and promoted claims linking vaccines to autism even though scientific studies and public health authorities have found no evidence of a link.
WHO spokesperson Tarik Jašarević told a press briefing in Geneva that vaccination recommendations were based on more than 60 years of research by WHO, national authorities and independent expert groups.

The timing of individual vaccines was determined through extensive scientific review of when people were most vulnerable to particular diseases and the development of the immune system, Jašarević told reporters in Geneva.
Jašarević said countries typically relied on national immunisation technical advisory groups made up of multidisciplinary experts who provided independent, evidence-based recommendations to governments and vaccination programme managers. Those groups, he said, draw on guidance from WHO’s Strategic Advisory Group of Experts on Immunization (SAGE) when establishing national schedules.
“What comes out from WHO is science-based,” Jašarević said.
“We hope that all countries will use this best scientific evidence that we have.”
SEPARATE SHOTS FOR MEASLES, MUMPS AND RUBELLA
Trump’s executive order has drawn criticism from medical associations, public health experts and vaccine manufacturers, who say there is no new scientific evidence to justify the changes and that the existing U.S. schedule reflects decades of evidence and the specific health needs of Americans, rejecting the comparison to other countries.

Physicians have warned that reducing the number of recommended vaccinations could leave more children vulnerable to preventable diseases and create confusion among parents about when children should be immunised.
The Trump order also recommends separating the combined measles, mumps and rubella (MMR) vaccine into three individual injections. Vaccine maker Merck has said there is no published scientific evidence showing a benefit from splitting the shot and warned that requiring separate visits could increase the risk of delayed or missed vaccinations.
