About
This page provides an update on receipt of vaccination and intent for vaccination among children for COVID-19 and influenza based on weekly updated National Immunization Survey (NIS) findings. NIS estimates are based on survey responses rather than vaccine administration records.
Vaccines
CDC recommends that all people aged 6 months and older stay up to date on COVID-19 vaccines and receive a seasonal flu vaccine. CDC also recommends nirsevimab, a monoclonal antibody product, for all infants younger than 8 months who are born during – or entering – their first RSV season, as well as some older babies.

Data Notes
- Source: National Immunization Survey-Flu (NIS-Flu) and National Immunization Survey-Child COVID Module (NIS-CCM, October 2023-December 2023 only).
- The data shown for the week ending June 30, 2024, includes the additional day of data collected on June 30, 2024.
- Starting January 2, 2024, intent for child influenza vaccination was no longer collected by the NIS-Flu.
- COVID-19 vaccination coverage and intent estimates through December 30, 2023 were based on survey interviews from the NIS-CCM. The NIS-CCM was discontinued at the end of December 2023. Starting in January 2024, COVID-19 vaccination and intent survey questions were included in the NIS-Flu and estimates reported here are based on that data.
- Data collection for influenza vaccination of children from NIS-Flu started October 1, 2023.
- Additional information available at: About the National Immunization Surveys.
- Vaccination coverage estimates are based on all interviews through the current week and represent approximately the cumulative percent vaccinated by mid-week. Each week, estimates for prior weeks are recalculated using the additional interviews conducted that week (combined with all previous interviews). Estimates for vaccination intent are based on interviews conducted that week and are adjusted to the cumulative vaccination coverage estimate for that week.
- Confidence Intervals (CI) describe the level of uncertainty around an estimate because a sample was taken via a survey. 95% CIs represent the range of values that would result if the data collection had been repeated many times. For a 95% CI, if the sampling method is repeated many times, the value would fall within this interval at least 95% of the time. Wider CIs reflect larger random error in estimates resulting from survey sampling.
- COVID-19 vaccination coverage estimates presented in this report represent uptake or intent for uptake of the updated 2023-2024 COVID-19 vaccine; uptake of the bivalent or other historic COVID-19 vaccination types are not included in estimates.
- Estimates from the NIS-CCM and NIS-Flu may differ from estimates based on other data sources, and are subject to errors resulting from incomplete sample frame (exclusion of households without cell phones), selection bias (survey respondents may be more likely to be vaccinated than non-respondents), and errors in self or parental reported vaccination status. Estimates are weighted to selected sociodemographic characteristics of the U.S. population to reduce possible bias from incomplete sample frame and selection bias.
