Weekly Respiratory Virus Vaccination Data, Children 6 Months-17 Years and Adults 18 Years and Older, National Immunization Survey

data.cdc.gov | Last Updated 10 May 2024

The weekly respiratory virus vaccination data come from the National Immunization Survey-Adult COVID Module (NIS-ACM), National Immunization Survey-Child COVID Module (NIS-CCM), and the National Immunization Survey-Flu (NIS-Flu). The NIS-ACM provides data on Influenza (flu), COVID-19, and RSV vaccination for adults aged ≥18 years in the United States. The NIS-CCM provides data on COVID-19 vaccination for children aged 6 months-17 years in the United States. The NIS-Flu provides data on Influenza vaccination for children aged 6 months-17 years in the United States National Immunization Survey data are collected by telephone interview using a random-digit-dialed sample of cellular 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), and Guam, Puerto Rico, and the United States Virgin Islands. Data are weighted to represent the non-institutionalized United States population and mitigate possible bias that can result from incomplete sample frame (exclusion of households with no phone service or only landline telephones) or non-response. All responses are self-reported, or reported by a parent for children 6 months-17 years. For more information about the surveys, see https://www.cdc.gov/vaccines/imz-managers/nis/about.html#current-surveys. Estimates should be interpreted with caution when there is a small sample size or wide confidence interval.

n_unweightedn_unweightedtextThe unweighted number of respondents in the denominator used to calculate the proportion estimates.
suppression_flagsuppression_flagtextUp-to-date estimates are suppressed (missing) and have a value of 1 for this field if the cumulative sample size across all weeks is less than 30 or if the most recent week sample size is less than 5. Four-level vaccination and intent estimates are suppressed (missing) and have a value of 1 for this field if direct estimate sample size for a specific week is less than 30 or if the up-to-date estimate is suppressed. If the estimate was not suppressed, this field has a value of 0.
