Immunizations on the rise in the U.S.

According to a U.S. Centers for Disease Control and Prevention survey, more young children are receiving immunizations in the U.S. for preventable diseases such as measles, mumps, rubella and hepatitis A.

The percentage of children ages 19 to 35 months who received one or more doses of the measles, mumps and rubella vaccine increased from 90 percent in 2009 to 91.5 percent in 2010. Experts were concerned that child immunization levels might fall due to some parents' concerns about vaccine safety, Reuters reports.

According to the CDC's National Immunization Survey of over 17,000 households, rotavirus vaccinations jumped from 43.9 percent in 2009 to 59.2 percent in 2010. The survey examined children born between January 2007 and July 2009.

The percentage of children who received the full series of Haemophilus influenzae type b vaccine rose from 54.8 percent to 66.8 percent.

"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," Dr. Anne Schuchat, the director of the CDC's National Center for Immunization and Respiratory Diseases, said, according to Reuters. "We recommend vaccinations because they are one of the most effective, safest ways to keep children healthy."

Despite repeated reassurances from health authorities, fears that vaccines might cause autism or other health problems have led some parents to skip vaccinations. In late August, a federal panel of experts concluded that vaccines cause very few side effects and found no evidence that they cause type 1 diabetes or autism.

The survey found that while there were no disparities in immunization rates by race for most vaccines, children living below the poverty line had lower vaccination rates for some diseases than other children.
