CDC released a national survey which found that immunization rates for children 19-35 months of age for most vaccine-preventable diseases are increasing or being sustained at high levels, with rates for most of the long-standing recommended vaccines are at or above 90 percent. Anne Schuchat, M.D., director of CDC’s National Center for Immunization and Respiratory Diseases, commented, “Today’s report is reassuring because it means that most parents are protecting their young children from diseases that can cause widespread and sometimes severe harm. We recommend vaccinations because they are one of the most effective, safest ways to keep children healthy.”

The 2010 National Immunization Survey (NIS) included “more than 17,000 households looked at children born between January 2007 and July 2009. Compared with the previous year, vaccine coverage increased for many vaccine-preventable diseases, including measles, mumps and rubella, rotavirus, pneumococcal disease, hepatitis A, and Haemophilus influenza type B (Hib).  Results from the survey also indicated that vaccination coverage rates against poliovirus, varicella (chickenpox) and the full series of hepatitis B remained stable at or above 90 percent.” http://www.cdc.gov/media/releases/2011/p0901_cdc_nationalsurvey.html
