What are the vaccination rates for one- to three-year-olds in SLC member states?

On August 27, 2015, the U.S. Centers for Disease Control & Prevention released data from the 2014 National Immunization Survey (NIS) looking at immunization coverage among children 19-35 months of age with state-level estimates, along with vaccination coverage among children at school entry by state during the 2014-2015 school year. Vaccines remain one of the most effective tools available for the prevention of childhood diseases. Since 1994, NIS has monitored vaccination coverage among U.S. children aged 19‐35 months for vaccines recommended by the Advisory Committee on Immunization Practices. To gauge progress toward achieving full vaccination with recommended childhood vaccines, observed coverage levels are compared to targets set by Healthy People 2020.

* A combined vaccine series is defined by the Centers for Disease Control & Prevention as:

  • Four or more doses of diphtheria, tetanus, and acellular pertussis vaccine;
  • Three or more doses of poliovirus vaccine;
  • One or more doses of measles-containing vaccine;
  • Full series of Haemophilus influenzae type b vaccine (three to four or more doses, depending on product type);
  • Three or more doses of hepatitis B vaccine;
  • One or more doses of varicella vaccine; and
  • Four or more doses of pneumococcal conjugate vaccine.
