针对新冠肺炎的疫苗已经以前所未有的时间开发出来。然而，任何疫苗的有效性都取决于愿意接种疫苗的人口比例。这项基于人群的观察性研究检查了在整个疫情期间接种新冠肺炎疫苗的意图。2020年11月，对参加了解美国研究的7547名美国成年人的全国代表性样本的纵向数据进行了多项Logistic回归分析。在2020年4月至10月进行的13项评估中，参与者报告愿意、犹豫不决和不愿接种新冠肺炎疫苗。公众对接种新冠肺炎疫苗的态度也用4分的利克特量表进行了评估。疫苗接种意愿从4月份的71%下降到10月份的53.6%。这是由于未决定接种疫苗的参与者比例增加(从10.5%增加到14.4%)和不愿意接种疫苗的样本比例增加(从18.5%增加到32%)。未决定/不愿意接种的人群亚组为：无学位者(RR=2.47，95%CI=2.04，3.00；不愿：RR=1.92，95%CI=1.67，2.20)；黑人参与者(未决定：RR=2.18，95%CI=1.73，2.74；不愿：RR=1.98，95%CI=1.63，2.42)；女性参与者(未决定：RR=1.41，95%CI=1.20，1.65；不愿：RR=1.29，95%CI=1.14，1.46)。年龄较大或收入较高的参与者最不可能犹豫不决或不愿接种疫苗。对疫苗潜在副作用的担忧是常见的。在疫情大流行期间，接种新冠肺炎疫苗的意愿迅速下降，近一半的美国人尚未决定或不愿接种疫苗。
Vaccines against COVID-19 have been developed in unprecedented time. However, the effectiveness of any vaccine is dictated by the proportion of the population willing to be vaccinated. This observational population-based study examines intentions to be vaccinated against COVID-19 throughout the pandemic. In November 2020, longitudinal data from a nationally representative sample of 7,547 U.S. adults enrolled in the Understanding America Study were analyzed using multinomial logistic regression. Participants reported being willing, undecided, and unwilling to get vaccinated against COVID-19 across 13 assessments conducted from April to October 2020. Public attitudes to vaccination against COVID-19 were also assessed on a 4-point Likert-type scale. Willingness to vaccinate declined from 71% in April to 53.6% in October. This was explained by an increase in the percentage of participants undecided about vaccinating (from 10.5% to 14.4%) and the proportion of the sample unwilling to vaccinate (from 18.5% to 32%). The population subgroups most likely to be undecided/unwilling to vaccinate were those without a degree (undecided: RR=2.47, 95% CI=2.04, 3.00; unwilling: RR=1.92, 95% CI=1.67, 2.20), Black participants (undecided: RR=2.18, 95% CI=1.73, 2.74; unwilling: RR=1.98, 95% CI=1.63, 2.42), and female participants (undecided: RR=1.41, 95% CI=1.20, 1.65; unwilling: RR=1.29, 95% CI=1.14, 1.46). Participants who were older or were on higher incomes were least likely to be undecided or unwilling to vaccinate. Concerns about potential side effects of a vaccine were common. Intentions to be vaccinated against COVID-19 have declined rapidly during the pandemic, and close to half of Americans are undecided or unwilling to be vaccinated.
