Weekly Cumulative Influenza Vaccination Coverage and Comparison Between 2025–26 and Previous Seasons± by Jurisdiction, Children 6 Months–17 Years, United States

• Weekly Cumulative Influenza Vaccination Coverage and Comparison Between 2025–26 and Previous Seasons by Jurisdiction, Children 6 Months–17, United States. • Weekly Influenza vaccination coverage and parental intent for vaccination among children is calculated using data from the National Immunization Survey–Flu (NIS–Flu) (https://www.cdc.gov/nis/about/index.html). NIS–Flu is a national random-digit-dialed cellular telephone survey of households with children ages 6 months–17 years conducted during October-June. The respondent to a NIS–Flu 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. • The NIS-Flu data posted on the dashboard below are currently a few days behind the data that are posted on the Respiratory Illnesses Data Channel (https://www.cdc.gov/respiratory-viruses/data/index.html). This lag is due to the time it takes to review data by geographic and sociodemographic characteristics and summarize the findings.
