COVID-19 Primary Series Completion, Booster Dose Eligibility, and Booster Dose Receipt by Age, United States

This site provides historical data beginning June 22, 2022, for the visualization presented on <a href="https://covid.cdc.gov/covid-data-tracker/#vaccinations" target="_blank">COVID-19 Data Tracker’s “Vaccinations in the United States”</a> site titled “Primary Series Completion, Booster Dose Eligibility, and Booster Dose Receipt by Age, United States”.

<b >Fully Vaccinated / Completed Primary Series:</b> <ul><li> For surveillance purposes, COVID Data Tracker counts people as being "fully vaccinated" or as having "completed a primary series" if they received two doses on different days (regardless of time interval) of the two-dose mRNA series or received one dose of a single-dose vaccine. When the vaccine manufacturer is not reported, the recipient is considered fully vaccinated with two doses.</li></ul><b>First Booster Dose:  </b><ul><li>For surveillance purposes, the count and percentage of people who received a first booster dose includes anyone who is fully vaccinated and has received another dose of COVID-19 vaccine since August 13, 2021. This includes people who received a first booster dose and people who received an additional primary series dose as this metric does not distinguish if the recipient is <b><a href='https://www.cdc.gov/coronavirus/2019-ncov/vaccines/recommendations/immuno.html' target="_blank"> immunocompromised and received an additional dose</a></b>.</li><li><b> First booster dose eligibility: </b><ul><li>CDC counts people as being <b>" <a href="https://www.cdc.gov/coronavirus/2019-ncov/vaccines/booster-shot.html" target="_blank">eligible for a first booster dose</a>"</b> if it has been at least 5 months since completion of a Pfizer-BioNTech or Moderna primary series or at least 2 months since receipt of a Janssen (Johnson & Johnson) singe-dose vaccine. </li></ul></li></ul>
<b>Second Booster Dose:</b><ul><li>For surveillance purposes, the count and percentage of people who received a second booster dose includes anyone who is fully vaccinated and has received two subsequent doses of COVID-19 vaccine since August 13, 2021. This includes people who received two booster doses and people who received one additional dose and one booster dose.  </li><li>The count of people who received a second booster dose and the percentage of people with a first booster who received a second booster dose does not account for whether a person is <b><a href='https://www.cdc.gov/coronavirus/2019-ncov/vaccines/recommendations/immuno.html' target="_blank">immunocompromised or time interval since first booster dose</a></b>. </li><li><b>Second booster dose eligibility: </b><ul><li>CDC counts people as being  <b>"<a href="https://www.cdc.gov/coronavirus/2019-ncov/vaccines/booster-shot.html" target="_blank"><b>eligible for a second booster dose</b></a>" </b> if it has been at least 4 months since receiving a first booster dose. </ul></li></li><li><b>Limitations to counting people with a second booster dose: </b>
<ul><li>Due to the aggregate vaccination record reporting method used by Idaho for its residents under the age of 18 years and by Texas for all its residents, CDC counts all 4th doses received by these populations as a second booster dose. This includes immunocompromised individuals who received a three-dose primary series and only one booster dose. This limitation may lead to an undercount of people who received the single-dose J&J/Janssen vaccine as their primary series and two booster doses.</li></ul>

本平台提供自2022年6月22日起的历史数据，用于可视化展示于<a href="https://covid.cdc.gov/covid-data-tracker/#vaccinations" target="_blank">COVID-19数据追踪系统“美国疫苗接种”页面</a>中所示的“初级系列完成情况、加强针接种资格及接种情况按年龄分布，美国”相关内容。<b>完全接种疫苗/完成初级系列：</b>针对监测目的，COVID数据追踪系统将接受过两次不同日（无论时间间隔）的mRNA两剂疫苗系列或接受过单剂疫苗一剂的人士视为“完全接种疫苗”或“完成初级系列”。当未报告疫苗制造商时，接受者被视为接受了两次剂量的完全疫苗接种。<ul><li>第一剂加强针：</li></ul><b>第一剂加强针接种资格：</b><ul><li>美国疾病控制与预防中心（CDC）将至少自完成辉瑞-生物科技或莫德纳初级系列以来已满5个月，或自接种强生（Johnson & Johnson）单剂疫苗以来已满2个月的人士视为“有资格接种第一剂加强针”。</li></ul><b>第二剂加强针：</b><ul><li>针对监测目的，接受过第二剂加强针的人数和百分比包括自2021年8月13日起已完全接种疫苗且接种过两剂COVID-19疫苗的人士。这包括接受过两剂加强针和接受过一剂额外初级系列剂量的人士。</li></ul><b>第二剂加强针接种资格：</b><ul><li>CDC将至少自接种第一剂加强针以来已满4个月的人士视为“有资格接种第二剂加强针”。</li></ul><b>第二剂加强针统计的限制：</b><ul><li>由于爱达荷州对其18岁以下居民和德克萨斯州对其所有居民使用的汇总疫苗接种记录报告方法，CDC将这些人群接受的第四剂疫苗均计为第二剂加强针。这包括接受了三剂初级系列和仅一剂加强针的免疫功能低下个体。此限制可能导致接受单剂强生（J&J/Janssen）疫苗作为其初级系列并接种了两剂加强针的人士被低估。</li></ul>数据代表所有疫苗合作伙伴，包括辖区合作伙伴诊所、零售药店、长期护理设施、透析中心、联邦紧急事务管理署和卫生资源与服务管理局合作伙伴站点以及联邦实体设施。
