Immunization Evaluation

Each year the Utah Immunization Program conducts statewide immunization assessments among two-year-old children in each of the local health department clinics. Site visits and immunization assessments of private providers enrolled in the Vaccines for Children (VFC) Program are also conducted. This data is used to determine current immunization levels, assist public and private immunization providers improve their delivery of immunization services, and subsequently, prevent vaccine-preventable disease outbreaks.

Coverage levels are determined by assessing the basic childhood immunization series, commonly referred to as the 4:3:1:3:3:1:4 series: 4 DTaP (Diphtheria, Tetanus, Pertussis), 3 Polio, 1 MMR (Measles, Mumps, Rubella), 3 Hib (Haemophilus influenzae type b), 3 Hepatitis B vaccines, 1 Chickenpox vaccine and 4 Pneumococcal Conjugate vaccines.  National childhood immunization coverage levels in collected in 2018 revealed that 68.7% of the nation’s two-year-old children (birth year 2016) received the 4:3:1:3:3:1:4 series compared to 72.0% of Utah’s children.

The Utah Immunization Program uses data in the Utah Statewide Immunization Information System (USIIS) to determine immunization levels. Clinics are able to conduct self-assessments if they are enrolled in USIIS. To find more about USIIS or to enroll in USIIS, click here.   

The Utah Immunization Program, along with public and private immunization providers, will continue to monitor immunization levels in Utah’s children and implement strategies to help improve them.
