Footnotes,"Data from parents and guardians of children and adolescents ages 6 months – 17 years are collected by telephone interview using a random-digit-dialed sample of cell telephone numbers stratified by state, the District of Columbia, five local jurisdictions (Bexar County, TX; Chicago, IL; Houston, TX; New York City, NY; and Philadelphia County, PA), Guam (April-July 2021, April-June 2022, and April-July 2023 only), Puerto Rico, and the U.S. Virgin Islands (April-December 2021 and January-September 2023 only). Data are weighted to represent the non-institutionalized U.S. population of children and adolescents ages 6 months – 17 years and to mitigate possible bias that can result from incomplete sample frames (e.g., exclusion of households with no phone service or only landline telephones) or non-response. The NIS-CCM survey weights adjust for nonresponse and households without mobile telephones. All responses are reported by the parent or guardian for their age-eligible child or adolescent. For more information about the survey, see the NIS website at https://www.cdc.gov/vaccines/imz-managers/nis/about.html#current-surveys. Estimates from NIS-CCM are subject to random error related to taking a sample (see definition of confidence interval below), and possible systematic errors. Systematic errors can result from incomplete sample frame (exclusion of households without cell phones), selection bias (survey respondents may be more likely to be vaccinated than non-respondents), and errors in self or parental reported vaccination status. Estimates are weighted to selected sociodemographic characteristics of the U.S. population to reduce possible bias from incomplete sample frame and selection bias. Estimates from the NIS-CCM may differ from estimates based on other data sources. Monthly estimates from NIS-CCM on this dashboard are based on proportions derived from the interviews that occurred only during the weeks assigned to the monthly analytic period. Due to sampling variability, once coverage reaches a plateau, minor fluctuations in estimates may result in coverage appearing to decrease from the month prior. These monthly estimates of vaccination coverage may differ from weekly estimates of vaccination coverage from NIS-ACM available here: https://www.cdc.gov/respiratory-viruses/data-research/dashboard/vaccination-trends-adults.html and https://www.cdc.gov/vaccines/imz-managers/coverage/covidvaxview/interactive/vaccination-dashboard.html, in which estimates of coverage are calculated for weekly data collection periods using a composite estimation procedure that uses data from completed interviews from the current week combined with data from all prior weeks, and are non-decreasing over time. Estimates for vaccination intent are based on interviews conducted each respective week and are adjusted to the cumulative vaccination coverage estimate for that week."
