The National Immunization Survey of 2012 found immunization of U.S. children ages 19-35 months remained high, with coverage for many routine vaccines remaining near or above 90 percent.
The random-digit-dialed telephone survey is used to monitor vaccination coverage among U.S. children age 19-35 months. This report describes national, state and selected local area vaccination coverage estimates for children born from January 2009 to May 2011.
In 2012, national vaccination coverage among children ages 19–35 months was 82.5 percent for more than four doses of diphtheria, pertussis and tetanus; 92.8 percent for more than three doses of poliovirus vaccine; 90.8 percent for more than one doses of the measles, mumps, and rubella vaccine; 89.7 percent for more than three doses of HepB and 90.2 percent for more than one dose of varicella vaccine.
Although the survey found a decline in coverage from 2011 of 1 percentage point to 2 percentage points for DTaP, poliovirus and HepB vaccines coverage for these vaccines has remained high and stable for at least the past decade, the report said.
The findings were published in the Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.
