IID-20 Data Details

Expand All

IID-20 Increase the number of States, the District of Columbia, and other reporting areas that have 80 percent of adolescents with 2 or more age-appropriate immunizations recorded in an immunization information system (IIS) among adolescents aged 11 to 18 years

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
Immunization Information Systems Annual Report (IISAR); Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases (CDC/NCIRD)
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
number
Baseline (Year): 
11 (2012)
Target: 
40
Target-Setting Method: 
Maintain consistency with national programs, regulations, policies, and laws.
Target-Setting Method Justification: 
Approximately 88 percent of grantee immunization information systems collect immunization-related data from birth to death. Vaccines recommended for adolescents (e.g., Tdap, MCV, and HPV) are captured in immunization information systems. Because these are lifespan systems and because of increasing interoperability between electronic health records and immunization information systems, this target is achievable.
Numerator: 

Number of states, the District of Columbia, and other reporting areas that have 80 percent of persons aged 11 to 18 years with 2 or more age-appropriate immunizations recorded in their immunization information system

Comparable Healthy People 2010 Objective: 
Not applicable
Data Collection Frequency: 
Annual
Methodology Notes: 

    54 of 56 CDC immunization information systems awardees (50 states excluding CT and NH, the District of Columbia, and other reporting areas) track immunizations administered to children and adolescents. "Other reporting areas" are defined as the following five cities: Houston, San Antonio, Chicago, Philadelphia, and New York City. These 5 cities operate separately from their state programs. Data from these cities are not included in the state data.

    The following vaccines are included as age-appropriate immunizations for adolescents in this metric: Tdap/Td, HPV, meningococcal, seasonal influenza, pneumococcal, Hepatitis A, Hepatitis B, polio, MMR, and varicella.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2013, the original baseline and baseline year were revised from 14 (2009) to 11 (2012) because some reporting areas were using the old reporting definition (2+ immunizations administered at any age) rather than the new reporting definition (2+ immunizations age-appropriate immunizations). The target was not revised.
