Despite high vaccination coverage among US children, recent increases in measles cases underscore concerns that immunization rates fall short in some parts of the country.
About 90% of children aged 19 to 35 months completed the recommended vaccinations and less than 1% received no vaccines, according to the 2012 National Immunization Survey. But in 15 states, measles, mumps, and rubella coverage is below 90%, a level that federal health officials say is a warning sign that outbreaks may occur or that entire states may be vulnerable.
