Abstract

On April 13, 2021, the CDC announced that the administration of Johnson and Johnson's COVID-19 vaccine would be paused due to a rare blood clotting side effect in ~ 0.0001% of people given the vaccine. Most people who are hesitant to get a COVID-19 vaccine list potential side effects as their main concern (PEW, 2021); thus, it is likely that this announcement increased vaccine hesitancy among the American public. Two days after the CDC's announcement, we administered a survey to a group of 2,046 Americans to assess their changes in attitudes toward COVID-19 vaccines. The aim of this study was to investigate whether viewing icon arrays of side effect risk would prevent increases in COVID-19 vaccine hesitancy due to the announcement. We found that using icon arrays to illustrate the small chance of experiencing the blood clotting side effect significantly prevented increases in aversion toward the Johnson and Johnson vaccine as well as all other COVID-19 vaccines.

图标阵列可减少对 COVID-19 疫苗副作用的担忧：一项随机对照研究。

2021 年 4 月 13 日，美国疾病预防控制中心宣布，由于约 0.0001% 的接种者出现罕见的血液凝固副作用，强生公司的 COVID-19 疫苗将暂停接种。大多数犹豫是否接种 COVID-19 疫苗的人都将潜在的副作用列为主要顾虑（PEW，2021 年）；因此，这一公告很可能增加了美国公众对疫苗的犹豫。在疾病预防控制中心发布公告两天后，我们对 2046 名美国人进行了调查，以评估他们对 COVID-19 疫苗态度的变化。本研究的目的是调查查看副作用风险图标阵列是否会防止因该公告而导致 COVID-19 疫苗犹豫不决的增加。我们发现，使用图标阵列来说明发生血液凝固副作用的几率很小，这极大地防止了对强生疫苗以及所有其他 COVID-19 疫苗厌恶情绪的增加。
