COVID-19 Vaccinations by Race/Ethnicity and Age - ARCHIVED

NOTE: As of 2/16/2023 this table is no longer being updated. For information on COVID-19 Updated (Bivalent) Booster Coverage, go to https://data.ct.gov/Health-and-Human-Services/COVID-19-Updated-Bivalent-Booster-Coverage-By-Race/8267-bg4w.

Important change as of June 1, 2022

As of June 1, 2022, we will be using 2020 DPH provisional census estimates* to calculate vaccine coverage percentages by age at the state level. 2020 estimates will replace the 2019 estimates that have been used. Caution should be taken when making comparisons of percentages calculated using the 2019 and 2020 census estimates since observed difference may result from the shift in the denominator. The age groups in the state-level data tables will also be changing as a result of the switch to the new denominator.

_________________________________________________________________________________________

This table shows the number and percent of people that have initiated COVID-19 vaccination, are fully vaccinated and had additional dose 1 by race / ethnicity and age group.

All data in this report are preliminary; data for previous dates will be updated as new reports are received and data errors are corrected. The age groups in the state-level data tables will also be changing as a result of the switch to the new denominator.

Population size estimates are based on 2019 DPH census estimates until 5/26/2022. From 6/1/2022, 2020 DPH provisional census estimates are used.

In the data shown here, a person who has received at least one dose of COVID-19 vaccine is considered to have initiated vaccination. A person is considered fully vaccinated if he/she has completed a primary vaccination series by receiving 2 doses of the Pfizer, Novavax or Moderna vaccines or 1 dose of the Johnson & Johnson vaccine. The fully vaccinated are a subset of the people who have received at least one dose.

A person who completed a Pfizer, Moderna, Novavax or Johnson & Johnson primary series (as defined above) and then had an additional monovalent dose of COVID-19 vaccine is considered to have had additional dose 1. The additional dose may be Pfizer, Moderna, Novavax or Johnson & Johnson and may be a different type from the primary series. For people who had a primary Pfizer or Moderna series, additional dose 1 was counted starting August 18th, 2021. For people with a Johnson & Johnson primary series additional dose 1 was counted starting October 22nd, 2021. For most people, additional dose 1 is a booster. However, additional dose 1 may represent a supplement to the primary series for a people who is moderately or severely immunosuppressed. Bivalent booster administrations are not included in the additional dose 1 calculations.

The percent with at least one dose many be over-estimated, and the percent fully vaccinated and with additional dose 1 may be under-estimated because of vaccine administration records for individuals that cannot be linked because of differences in how names or date of birth are reported.

Race and ethnicity data may be self-reported or taken from an existing electronic health care record. Reported race and ethnicity information is used to create a single race/ethnicity variable. People with Hispanic ethnicity are classified as Hispanic regardless of reported race. People with a missing ethnicity are classified as non-Hispanic. People with more than one race are classified as multiple races.

A vaccine coverage percentage cannot be calculated for people classified as NH Other race or NH Unknown race since there are not population size estimates for these groups. Data quality assurance activities suggest that in at least some cases NH Other may represent a missing value. Vaccine coverage estimates in specific race/ethnicity groups may be underestimated as result of the classification of records as NH Unknown Race or NH Other Race.

Connecticut COVID-19 Vaccine Program providers are required to report information on all COVID-19 vaccine doses administered to CT WiZ, the Connecticut Immunization Information System. This includes doses given to residents of CT and to residents of other states vaccinated in CT. Data on doses administered to CT residents out-of-state are being added to CT WiZ jurisdiction-by-jurisdiction. Doses administered by some Federal entities (including Department of Defense, Department of Correction, Department of Veteran’s Affairs, Indian Health Service) are not yet reported to CT WiZ. Data reported here reflect the vaccination records reported to CT WiZ. However, once CT residents who have received doses in each jurisdiction are added to CT WiZ, the records for residents of that jurisdiction vaccinated in CT are removed. For example, when CT residents vaccinated in NYC were added, NYC residents vaccinated in CT were removed.

Note: This dataset takes the place of the original "COVID-19 Vaccinations by Race/Ethnicity" dataset (https://data.ct.gov/Health-and-Human-Services/COVID-19-Vaccinations-by-Race-Ethnicity/xkga-ifz3 ), which will not be updated after 5/20/2021 and “COVID-19 Vaccinations by Race / Ethnicity” dataset (https://data.ct.gov/Health-and-Human-Services/COVID-19-Vaccinations-by-Race-Ethnicity/ybkg-w5x2), which will not be updated after 10/20/2021.

自2022年6月1日起的重要变更

自2022年6月1日起，我们将采用2020年DPH临时人口普查估计值*来计算各州按年龄段的疫苗接种覆盖率百分比。2020年的估计值将取代之前使用的2019年估计值。在比较使用2019年和2020年人口普查估计值计算出的百分比时，应注意，观察到的差异可能源于分母的变化。由于转向新的分母，州级数据表中的年龄组也将发生变化。

_________________________________________________________________________________________

本表显示了按种族/民族和年龄组划分的已开始接种COVID-19疫苗、全程接种并额外接种第一剂疫苗的人数和百分比。

本报告中所有数据均为初步数据；随着新报告的接收和数据错误的纠正，以往日期的数据将进行更新。由于转向新的分母，州级数据表中的年龄组也将发生变化。

人口规模估计值基于2019年DPH人口普查估计值，直至2022年5月26日。从2022年6月1日起，使用2020年DPH临时人口普查估计值。

在此显示的数据中，已接种至少一剂COVID-19疫苗的人被视为已开始接种。如果某人通过接种辉瑞、Novavax或Moderna疫苗的2剂或强生疫苗的1剂完成了初级疫苗接种系列，则被视为全程接种。全程接种者是至少接种过一剂疫苗的人群的子集。

完成了辉瑞、Moderna、Novavax或强生初级系列（如上所述）并随后接种了额外的单价第一剂COVID-19疫苗的人被视为已接种额外第一剂。额外剂量可以是辉瑞、Moderna、Novavax或强生，且可能与初级系列不同。对于接种了辉瑞或Moderna初级系列的人，额外第一剂的计数始于2021年8月18日。对于接种了强生初级系列的人，额外第一剂的计数始于2021年10月22日。对于大多数人来说，额外第一剂是加强剂。然而，对于中度或重度免疫抑制的人群，额外第一剂可能代表对初级系列的补充。二价加强剂接种不包括在额外第一剂的计算中。

由于无法将某些个人的疫苗接种记录链接起来，因为姓名或出生日期的报告方式不同，因此至少一剂的人数可能会被高估，而全程接种并额外接种第一剂的人数可能会被低估。由于种族和民族数据可能为自我报告或来自现有的电子健康记录，因此报告的种族和民族信息用于创建一个单一的种族/民族变量。具有西班牙裔民族身份的人无论报告的种族如何均被视为西班牙裔。民族信息缺失的人被视为非西班牙裔。具有多个种族的人被视为多个种族。

无法为被归类为NH其他种族或NH未知种族的人群计算疫苗接种覆盖率百分比，因为这些群体没有人口规模估计值。数据质量保证活动表明，在至少某些情况下，NH其他可能代表缺失值。由于将记录归类为NH未知种族或NH其他种族，特定种族/民族群体的疫苗接种覆盖率估计值可能被低估。

康涅狄格州COVID-19疫苗接种计划提供者必须向康涅狄格州WiZ（康涅狄格州免疫信息系统）报告所有向CT WiZ提供的COVID-19疫苗剂量的信息。这包括向康涅狄格州居民和其他在康涅狄格州接种疫苗的州居民提供的剂量。正在将康涅狄格州居民在州外接种疫苗的剂量添加到CT WiZ的按司法管辖区划分的管辖范围内。一些联邦机构（包括国防部、矫正部、退伍军人事务部、印第安人卫生服务）尚未向CT WiZ报告剂量。此处报告的数据反映报告给CT WiZ的疫苗接种记录。然而，一旦将每个司法管辖区接种疫苗的CT居民添加到CT WiZ，在该司法管辖区接种疫苗的该辖区居民的记录将被删除。例如，当在纽约市接种疫苗的CT居民被添加到CT WiZ时，在康涅狄格州接种疫苗的纽约市居民的记录将被删除。

注意：本数据集替代了原始的“按种族/民族划分的COVID-19疫苗接种”数据集（https://data.ct.gov/Health-and-Human-Services/COVID-19-Vaccinations-by-Race-Ethnicity/xkga-ifz3），该数据集在2021年5月20日之后将不再更新，以及“按种族/民族划分的COVID-19疫苗接种”数据集（https://data.ct.gov/Health-and-Human-Services/COVID-19-Vaccinations-by-Race-Ethnicity/ybkg-w5x2），该数据集在2021年10月20日之后将不再更新。
