National Immunization Survey Adult COVID Module (NIS-ACM): Vaccination Status and Intent by Demographics

National Immunization Survey Adult COVID Module (NIS-ACM): CDC is providing information on COVID-19 vaccine confidence to supplement vaccine administration data. These data represent trends in vaccination status and intent by demographics.

Following collection of August 2021 survey data, an error in data processing led to incorrect categorization of some survey respondents; some respondents who should have been categorized as MSA: Principal City instead were categorized as MSA: Non-Principal City. Data downloaded during the period September 12, 2021 through September 30, 2021 may have incorrect estimates by MSA status, SVI of county of residence, and political leaning of county of residence.

国家免疫调查成人COVID模块（NIS-ACM）：美国疾病控制与预防中心（CDC）提供有关COVID-19疫苗接种信心的信息，以补充疫苗接种数据。这些数据反映了疫苗接种状况及意愿的群体趋势。在2021年8月收集的调查数据之后，数据处理过程中出现错误，导致部分受访者分类错误；一些本应被归类为MSA：主要城市受访者却被错误地归类为MSA：非主要城市。2021年9月12日至9月30日期间下载的数据可能存在MSA状态、居住县的健康服务可及性指数（SVI）以及居住县的政治倾向等方面的估计误差。
