Health Indicator Report of Immunizations: recommended immunizations by age 24 months

Notes

This data is from the National Immunization Survey (NIS). NIS reports these vaccine coverage estimates for 24-month-old children by birth year (i.e. 2023 survey data contains estimates for the 24 month old children from birth year 2021).

Data Source

National Immunization Survey, National Center for Health Statistics, U.S. Centers for Disease Control and Prevention

Data Interpretation Issues

The National Immunization Survey (NIS) is conducted by the Centers for Disease Control and Prevention (CDC) and uses a random-digit-dialing sample of landline and cellular telephone numbers to find households throughout the U.S. with children who are or will be 19-35 months within a few weeks of being selected to participate in the survey. Data are used to monitor vaccination coverage among 2-year-old children at the national, state, selected local levels, and some in U.S. territories. Interviewers ask parents or guardians to tell them which vaccines (with dates) appear on the child's "shot card" kept in the home, and they also collect demographic and socioeconomic information. At the end of the interview, they ask for permission to contact the child's vaccination providers. Vaccine providers are then contacted by mail to verify each child's vaccinations. The NIS uses a nationally representative sample, and provides estimates of coverage that are weighted to represent the entire population, nationally, and by region, state, and selected large metro areas. The large sample size (approximately 15,000) allows them to stratify (that is, subdivide) the data so that they can examine vaccination rates among different groups, for instance by income level, race, education level of mothers, and other factors. In previous years NIS Child data was reported for 19-35 month old children by survey year. However, in 2019 NIS began reporting immunization estimates based on the birth year. At the time of the change, the birth year estimates were made available back to birth year 2013 and are displayed in an accompanying data view in this Indicator Report.

How Are We Doing?

Coverage levels in Utah have generally increased in the past 8 years from 67.2% of 2-year-old children fully immunized in 2013 to 79.0% in 2020. It should be noted that the estimate for this measure decreased from 79.0% in 2020 to 74.9% in 2023. However, the estimate of coverage in children aged 24 months for 2023 is preliminary and will be revised with the coming year's survey estimate as more children in this birth cohort are added to the survey results. These data typically fluctuate from year to year and it is useful to look at 5-10 year trends to gain a clear understanding of how well children are being immunized in Utah.

How Do We Compare With the U.S.?

The Utah coverage rate for 4:3:1:3:3:1:4 immunization among 24-month-old children with the birth year 2021 was 74.9% while the United States coverage rate was 66.1%. Utah ranked 5th out of 50 states for this measure.

What Is Being Done?

The Utah Department of Health and Human Services Immunization Program conducts annual assessments of private and public health care providers' immunization records to obtain state immunization levels. During these site visits, Utah Immunization Program provider representatives also train clinic staff on appropriate vaccine storage, handling, and administration according to the Advisory Committee on Immunization Practices (ACIP) recommended practices. Utah also has immunization coalitions that are working to maintain or improve current levels of immunization and to increase public awareness of immunizations. The Utah Statewide Immunization Information System (USIIS) provides a mechanism for health care providers to track patient immunizations and send reminder cards to Utah parents whose children are due for immunizations. The USIIS also includes adult immunizations such as pneumonia, tetanus, and influenza. Due to the increased costs of vaccine, public health clinics are now able to provide publicly purchased vaccine only to those who meet eligibility criteria and don't have insurance coverage.

Available Services

Vaccines for Children (VFC) Program: This program provides vaccines to participating providers for children birth through 18 years of age who meet at least one of the following criteria: *Enrolled in Medicaid *Enrolled in the Utah Children's Health Insurance Program *Not insured: A child who has no health insurance coverage *American Indian or Alaska Native: As defined by the Indian Health Care Improvement Act (25 U.S.C. 1603) *Under-insured: A child who has commercial (private) health insurance but the coverage does not include vaccines, a child whose insurance covers only selected vaccines (VFC-eligible for non-covered vaccines only), or a child whose insurance caps vaccine coverage at a certain amount. Once that coverage amount is reached, the child is categorized as under-insured. Under-insured children are eligible to receive VFC vaccine only through a Federally Qualified Health Center (FQHC) or Rural Health Clinic (RHC).[[br]] [[br]] Information about VFC is available on our website at: [https://immunize.utah.gov/vaccines-for-children-program/].
