SARS-CoV-2 疫苗接种后月经出血变化趋势
Trends in menstrual bleeding changes after SARS-CoV-2 vaccination

导读
这篇论文通过大规模问卷调查研究了接种 SARS-CoV-2 疫苗后月经出血变化的情况,发现相当比例的受访者报告了经量变化、周期推迟等现象。作者强调该调查设计无法与一般人群比较发生率,所描述的关联并非因果关系,且此类月经变化通常不代表生育能力受损。
HN 关注点:疫苗对月经的影响这一曾被忽视的研究空白,以及疫苗试验仅监测 7 天不良事件的做法是否合理。

亲历亲历者证实社区早有观察,批评当时月经研究被忽视、质疑即被污名化
我接种疫苗时正在备孕,这结果不意外。备孕社区非常数据导向,大家一直在报告基础体温升高、排卵推迟、月经推迟。当时关于月经的研究少得令人失望——我们被告知疫苗绝对安全,甚至质疑一下就被扣上‘反疫苗’的帽子。一年多后科学界才证实论坛上早就流传的说法。疫苗可能是安全的,但除了确认流产率不变,没人真正关心它对月经和怀孕的影响。

As someone who was trying to conceive while the vaccine rolled out, this isn’t surprising. People were regularly reporting basal temperature spikes, delayed ovulation, and delayed periods. This is a community that is extremely data-oriented, since with the right measurements you’re able to predict your fertile (or non-fertile) window. I was disappointed to see how little research there was into menstruation at the time. We were told that the vaccine was perfectly safe, and even questioning the vaccine made you ‘anti-vax.’ Now over a full year later the scientific community is confirming what random message boards have been saying all along. It may be safe, but nobody really cared to look at the impact on menstruation or pregnancy beyond confirming that the rate of miscarriage is unchanged.
质疑质疑疫苗试验仅监测 7 天不良事件的标准是否充分
‘疫苗试验方案通常只监测 7 天内的重大不良事件’——这让我震惊。七天?难道没有理由认为疫苗可能在超过一周后才出现不良反应吗?

"Vaccine trial protocols do not typically monitor for major adverse events for more than 7 days" I am stunned by this. Seven days? Is there really no reason to think that a vaccine candidate might have adverse effects more than a week later?
补充指出科学家当时已解释病毒和疫苗改变月经并不罕见
当初人们开始讨论时,我听到的说法是其他病毒和疫苗本来就常常改变月经周期,所以这并不奇怪也不值得恐慌。

When people first talked about it, I was hearing scientists saying that both other viruses and vaccines often change periods, and thus it wasn’t surprising/alarming
补充引用论文原文澄清:调查非因果、发生率不可外推、不影响生育
这项调查的性质意味着无法将样本中的发生率与一般人群比较(样本中 40% 有某经历不代表现实中也是 40%)。这些关联不是因果性的,只是为进一步研究提供证据。我们强调这类月经变化通常不代表生育能力的变化。

> What else should I know about this research? > The nature of this survey means that we cannot compare the incidence of different experiences here with the general population (meaning, 40% of this sample having an experience does not mean that is the rate of that experience out in the world). The associations described here are not causal but provide evidence to better study these trends further. We emphasize that menstrual bleeding changes of this nature are generally not indicative of changes to fertility.
