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 2024The 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.
