• Weekly Cumulative Percentage of Children 6 Months–17 Years Who Are Up to Date with COVID-19 Vaccines and Comparison Between 2025–26 and Previous Seasons, by Jurisdiction.

• 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) (https://www.cdc.gov/nis/about/index.html). The NIS-CCM was discontinued at the end of 2023 and questions regarding COVID-19 vaccination status and intent were added to the National Immunization Survey-Flu (NIS-Flu) (https://www.cdc.gov/nis/about/index.html).

• NIS-CCM and NIS-Flu are national random-digit dial cellular telephone surveys of households with children ages 6 months through 17 years; NIS-Flu is 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.

• Weekly comparisons to previous season should take into account differences between seasons in vaccine availability dates. 2023–24 COVID-19 vaccines were first available mid-September 2023, and 2024–25 and 2025–26 COVID-19 vaccines were first available at the end of August 2024 and 2025, respectively. 

• 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.
