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.
2021 年 4 月 13 日，由于接受疫苗注射的人群中约有 0.0001%出现罕见的血栓副作用，美国疾病控制与预防中心（CDC）宣布暂停使用强生公司的 COVID-19 疫苗。大多数对接种 COVID-19 疫苗犹豫不决的人将潜在的副作用列为他们主要关注的问题（PEW，2021 年）；因此，这一声明很可能增加了美国公众对疫苗的犹豫。在 CDC 宣布两天后，我们对一组 2046 名美国人进行了调查，以评估他们对 COVID-19 疫苗的态度变化。这项研究的目的是调查查看副作用风险的图标数组是否可以防止因该声明而导致对 COVID-19 疫苗的犹豫情绪增加。我们发现，使用图标数组来说明经历血栓副作用的小概率，可显著降低对强生公司和所有其他 COVID-19 疫苗的厌恶感。
