IID-9 Decrease the percentage of children in the United States who receive 0 doses of recommended vaccines by age 19 to 35 months

About the Data: National

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

Data Source: 
National Immunization Survey (NIS); Centers for Disease Control and Prevention, National Center for Immunization and Respiratory Diseases and National Center for Health Statistics (CDC/NCIRD and CDC/NCHS)
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent
Baseline (Year): 
0.8 (2012)
Target: 
Not applicable
Target-Setting Method: 
This measure is being tracked for informational purposes. If warranted, a target will be set during the decade.
Numerator: 

Number of children aged 19 to 35 months who receive zero doses of any recommended vaccines (including DTaP, Hib, measles-containing vaccine, polio, HepB, varicella, PCV, HepA, rotavirus, or influenza)

Denominator: 

Number of children aged 19 to 35 months

Comparable Healthy People 2010 Objective: 
Not applicable
Questions Used to Obtain the National Baseline Data: 

    From the 2013 National Immunization Survey Provider-Immunization History Questionnaire:

    [NUMERATOR:]

    Specify month, day, and year that each vaccine was given, either by the office or another provider, and type of vaccine, as documented in the records.

Data Collection Frequency: 
Annual
Methodology Notes: 

    The National Immunization Survey (NIS) uses a quarterly, random-digit-dialed sample of telephone numbers to reach households with children aged 19–35 months in the 50 states and selected local areas and territories, followed by a mail survey sent to the children's vaccination providers to collect vaccination information. Data are weighted to represent the population of children aged 19–35 months, with adjustments for households with multiple telephone lines and mixed telephone use (landline and cellular), household nonresponse, and exclusion of households without telephone service. Beginning in 2011, surveys include landline and cellular telephone households.

    This measure tracks the proportion of children aged 19 to 35 months receiving zero doses of any recommended vaccines (including DTaP, Hib, measles-containing vaccine, polio, HepB, varicella, PCV, HepA, rotavirus, or influenza).

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 2014, 2008 through 2011 data were revised to correct errors in programming, in particular the estimates by sex and country of birth. The baseline estimate for the total population and target remained the same. In 2015, the baseline year was revised from 2008 to 2012 due to expanding the sampling frame from landline phones only to a dual frame sample including landline and cell phones. The baseline statement was changed from "0.6 percent of children aged 19 to 35 months in 2008 in the United States received 0 doses of recommended vaccines by age 19 to 35 months" to "0.8 percent of children aged 19 to 35 months in 2012 in the United States received 0 doses of recommended vaccines by age 19 to 35 months." The target remains unchanged.
