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

Estimates should be interpreted with caution when there is a small sample size or wide confidence interval.
