Vaccination Coverage by Age 24 Months Among Children Born in 2016 and 2017 — National Immunization Survey-Child, United States, 2017–2019

Abstract

Immunization has been described as a "global health and development success story," and worldwide is estimated to prevent 2-3 million deaths annually.*In the United States, the Advisory Committee on Immunization Practices (ACIP) currently recommends vaccination against 14 potentially serious illnesses by the time a child reaches age 24 months (1).CDC monitors coverage with ACIP-recommended vaccines through the National Immunization Survey-Child (NIS-Child); data from the survey were used to estimate vaccination coverage at the national, regional, state, territorial, and selected local area levels † among children born in 2016 and 2017.National coverage by age 24 months was ≥90% for ≥3 doses of poliovirus vaccine, ≥3 doses of hepatitis B vaccine (HepB), and ≥1 dose of varicella vaccine (VAR); national coverage was ≥90% for ≥1 dose of measles, mumps, and rubella vaccine (MMR), although MMR coverage was <90% in 14 states.Coverage with ≥2 doses of influenza vaccine was higher for children born during 2016-2017 (58.1%) than for those born during 2014-2015 (53.8%) but was the lowest among all vaccines studied.Only 1.2% of children had received no vaccinations by age 24 months.Vaccination coverage among * https://www.who.int/health-topics/vaccines-and-immunization#tab=tab_1.† Estimates for states, selected local areas, and the territories of Guam and Puerto Rico are available online at https://www.cdc.gov/vaccines/imz-managers/ coverage/childvaxview/data-reports/index.html.Certain local areas that receive federal Section 317 immunization funds are sampled separately and included in the NIS-Child sample every year (Chicago, Illinois; New York, New York; Philadelphia County, Pennsylvania; Bexar County, Texas; and Houston, Texas).Other local areas in Texas were sampled in some survey years from 2017-2019 and not others, including El Paso County (survey years 2017 and 2019); Dallas County (survey years 2017 and 2019); Hidalgo County (survey year 2018); and Tarrant County (survey year 2018).Data collection in Puerto Rico was suspended during 2017 because of the severity of the hurricane season and did not occur at all in 2018.Therefore, estimates for Puerto Rico are based on partial data from 2017 and data collected in the full 2019 survey year.National estimates in this report exclude all territories.
