一项随机对照试验显示，最近关于COVID-19疫苗的网上错误信息导致英国和美国成年人接种疫苗的意愿下降。（SARS-CoV-2）将是2019年抗击冠状病毒疾病的下一个重要步骤（COVID-19）大流行，但实现高吸收率将是一项挑战，并可能受到网上错误信息的阻碍。为了为成功的疫苗接种活动提供信息，我们在英国和美国进行了一项随机对照试验，以量化接触COVID-19疫苗的在线错误信息如何影响接种疫苗以保护自己或他人的意图。在这里，我们表明，截至2020年9月，在这两个国家，“肯定”接种疫苗的人比群体免疫可能需要的人要少，而且，相对于事实信息，最近的错误信息导致意向下降6.2个百分点在那些表示他们肯定会接受疫苗的人中，英国和美国分别有6.4个百分点（第95百分位数区间3.9至8.5）和6.4个百分点（第95百分位数区间4.0至8.8）。我们还发现，一些社会人口群体受到暴露于错误信息的不同影响。最后，我们发现，听起来科学的错误信息与疫苗接种意愿的下降更密切相关。
A randomized controlled trial reveals that exposure to recent online misinformation around a COVID-19 vaccine induces a decline in intent to vaccinate among adults in the UK and the USA.Widespread acceptance of a vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) will be the next major step in fighting the coronavirus disease 2019 (COVID-19) pandemic, but achieving high uptake will be a challenge and may be impeded by online misinformation. To inform successful vaccination campaigns, we conducted a randomized controlled trial in the UK and the USA to quantify how exposure to online misinformation around COVID-19 vaccines affects intent to vaccinate to protect oneself or others. Here we show that in both countries-as of September 2020-fewer people would 'definitely' take a vaccine than is likely required for herd immunity, and that, relative to factual information, recent misinformation induced a decline in intent of 6.2 percentage points (95th percentile interval 3.9 to 8.5) in the UK and 6.4 percentage points (95th percentile interval 4.0 to 8.8) in the USA among those who stated that they would definitely accept a vaccine. We also find that some sociodemographic groups are differentially impacted by exposure to misinformation. Finally, we show that scientific-sounding misinformation is more strongly associated with declines in vaccination intent.
