According to a survey done by the Centers for Disease Control and Prevention, ninety percent or more of U.S children aged 19 to 35 months has received the recommended vaccinations in 2009. However, there was a general drop in measles vaccinations. Less than 1% of children did not receive any sort of vaccines.

The 2009 National Immunization Survey of more than 17,000 households investigated vaccination of children born between January 2006 and July 2008 and discovered that vaccine coverage stayed relatively firm, meeting the national Healthy People 2010 goal to have 90 percent or higher vacination.

"Nearly all parents are choosing to have their children protected against dangerous childhood diseases through vaccination," said Dr. Anne Schuchat, Director of the National Center for Immunization and Respiratory Diseases at CDC.

However, she added that “It’s likely there are still some communities with high numbers of under-vaccinated or unvaccinated children.”
