* All coverage estimates are for children reported to be vaccinated July 2017 through May 2018. Coverage estimates for children living in Guam included interviews April through
June 2018. All other estimates are for children with interviews October 2017 through June 2018.

^† Month of vaccination was imputed for respondents with missing month of vaccination data. Percentages are weighted to the U.S. population. For more information on imputation and
statistical methods see Estimates of Flu Vaccination Coverage among Children — United States, 2017–18 Flu Season.

^‡ Estimates not reliable because relative standard error is >0.3.

^§ “Rest of State” refers to the population of a state that does not reside in an area in which an influenza vaccination coverage estimate was calculated. For example,
Illinois-Rest of State refers to the population of Illinois excluding the City of Chicago.

^|| Estimates might not be reliable because confidence interval half-width is >10.

^¶ Data were not collected by the NIS-Flu in Puerto Rico or the U.S. Virgin Islands.
