Child Coverage and Parental Intent for Vaccination

COVID-19 Vaccination Coverage and Intent for Vaccination, Children 6 months through 17 years, United States

Weekly estimates of COVID-19 vaccination coverage and parental intent for vaccination among children through December 31, 2023 were calculated using data from the National Immunization Survey-Child COVID Module (NIS-CCM). Beginning January 2, 2024, the NIS-CCM was discontinued, and questions regarding receipt of COVID-19 vaccination among children were added to the NIS-Flu. The NIS-CCM and NIS-Flu are random-digit dial cellular telephone surveys of households with children ages 6 months through 17 years. The respondent to a NIS survey is a parent or guardian who said they were knowledgeable about the child’s vaccination history. All estimates are based upon parental report of receipt of vaccination and month of that vaccination.

Note: Confidence Intervals (CI) describe the level of uncertainty around an estimate because a sample was taken. 95% CIs represent the range of values that would result if the data collection had been repeated many times. For a 95% confidence interval, if the sampling method is repeated many times, the true value would fall within this interval at least 95% of the time. Wider CIs reflect larger random error in estimates resulting from survey sampling.

Estimates from the NIS may differ from estimates based on other data sources, and in addition to random error associated with taking a sample, are subject to errors resulting 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.

Health insurance status is not available from NIS-flu and was removed from the list of demographics beginning January 2, 2024.

*National estimates include 50 states and Washington D.C. The Office of Intergovernmental and External Affairs hosts 10 Regional Offices that directly serve state and local organizations; information about Regions and which states are included in each region is available

^†Up to date with the updated 2023-24 COVID-19 vaccine is defined as receipt of at least one vaccination since September 14, 2023 for children ≥5 years; for children <5 years, up-to-date status was defined based on the current recommendations that also take into account number of doses and brand of vaccine. Up to date status was determined by survey questions on month and year of most recent COVID vaccine, and for children <5 years, total number of COVID vaccinations received and brand of most recent COVID vaccine. Vaccination coverage estimates are based on all interviews through the current week and represent approximately the cumulative percent vaccinated by mid-week. Each week, estimates for prior weeks are recalculated using the additional interviews conducted that week (combined with all previous interviews).

^‡Cumulative vaccination coverage estimates are suppressed when the cumulative sample size is <30 or current week sample size is <5. Vaccination intent estimates for a given week are suppressed when the sample size for that week is <30.

^§Estimates for parental vaccination intent are based on interviews conducted during that week and are adjusted to the cumulative vaccination coverage estimate for that week.
