Immunization-Children is the percentage of children aged 19 to 35 months receiving the recommended doses of Diphtheria, Tetanus, and Pertussis (DTaP); polio; Measles, Mumps, Rubella (MMR); Haemophilus influenzae Type b (Hib); hepatitis B; varicella (chickenpox); and Pneumococcal conjugate vaccine (PCV) vaccines. This measure was adjusted from the 2010-2012 Editions which did not account for each individual receiving the full series of shots, but rather, individuals receiving individual shots. The 2015 ranks are based on 2014 data from the National Immunization Survey.
Immunization coverage among children ranges from a high of 84.7% in Maine to a low of 63.4% in West Virginia. In the United States, immunization coverage among children is 71.6% of children aged 19 to 35 months, up slightly from 70.4% in the 2014 Edition.
Public Health Impact
Early childhood immunization has been shown to be a safe and cost-effective means of controlling diseases. Infants receiving recommended immunizations by age 2 are protected from 14 diseases. Vaccinations have led to a 95% decrease in vaccine-preventable diseases in the last 50 years. The CDC has called vaccines 1 of the 10 greatest public health achievements of the 20th century. Routine childhood immunizations are estimated to save almost $10 billion in direct medical costs. The Affordable Care Act requires health insurance plans to cover preventive services, including immunizations, without charging deductibles, copayments, or coinsurance. The Guide to Community Preventive Services has proven methods to increase the rate of childhood vaccinations such as establishing vaccination programs in schools and childcare centers, designing interventions that increase community demand, and expanding access in health care settings.
Increasing the percentage of children aged 19 to 35 months who receive the recommended doses of DTaP, polio, MMR, Hib, hepatitis B, varicella, and PCV vaccines to 80.0% is a Healthy People 2020 leading health indicator.
