@Belinda Smith : 本期节目讨论了罗伯特·肯尼迪小儿子(RFK Jr.)的反疫苗立场及其对美国公共卫生的潜在影响。RFK Jr. 长期以来一直宣扬疫苗会导致自闭症的理论,该理论已被科学界广泛驳斥。他的观点对公众健康构成严重威胁,尤其是在他被提名为美国卫生部长的情况下。 我们需要关注的是,这种不实信息对公众健康造成的损害,以及如何通过科学证据来反驳这些不准确的论述。我们需要强调疫苗接种的重要性,以及其在预防疾病方面的作用。 此外,我们需要讨论如何应对和解决反疫苗运动,以及如何确保公众能够获得准确可靠的健康信息。 @Julie Leask : 我是悉尼大学的公共卫生研究员Julie Leask教授。我将解释为什么MMR疫苗如此重要,以及Andrew Wakefield的研究是如何将该疫苗与自闭症错误地联系起来的。 MMR疫苗预防麻疹、腮腺炎和风疹,这三种疾病都可能导致严重的健康问题甚至死亡。该疫苗安全有效,并且在全球范围内挽救了无数人的生命。 然而,Andrew Wakefield的一项研究曾声称MMR疫苗与自闭症之间存在联系,这项研究存在严重的缺陷,并且已经被撤稿。这项研究的结论是错误的,并且导致了疫苗接种率的下降,从而增加了疾病爆发的风险。 我们需要强调的是,没有科学证据支持疫苗会导致自闭症的观点。我们需要通过教育和宣传来纠正公众的误解,并确保每个人都能获得安全有效的疫苗接种。 @Fiona Pepper : 关于RFK Jr.的提名,目前存在巨大的争议。近20,000名医生和医护人员签署了一封反对其提名的信函。此外,来自两党的资深美国政界人士也公开表示反对。最终,美国参议院将决定是否接受他的提名。他的确认听证会日期尚未确定,最早可能在1月底举行。 我们需要关注的是,政治决策对公共卫生政策的影响,以及如何确保科学证据在决策中发挥关键作用。我们需要确保那些对公共卫生有深入了解的人能够担任重要的公共卫生职位。

Deep Dive

Chapters
This chapter explores the history of the debunked link between childhood vaccines and autism, focusing on Andrew Wakefield's discredited 1998 study published in The Lancet. It discusses the study's methodology, ethical concerns, and the lasting impact of the misinformation despite its retraction. The chapter also highlights the recent resurgence of this theory due to political figures.
  • Andrew Wakefield's 1998 study linking MMR vaccine to autism was retracted due to flawed methodology and ethical breaches.
  • The study's publication led to a significant drop in vaccination rates and subsequent measles outbreaks.
  • The misinformation continues to resurface, fueled by prominent figures.
  • Numerous studies have shown no link between MMR vaccine and autism.

Shownotes Transcript

Robert F Kennedy Jr is tipped to lead the US Department of Health and Human Services. Over the years, RFK Jr has repeatedly pushed the claim that childhood vaccines cause autism spectrum disorder — a theory that's been well and truly debunked.

So where did this idea come from? What's bowel disease got to do with it? And what might the US expect with an anti-vaxxer at the helm of health and human services?
