More than eight in 10 U.S. adults believe the measles, mumps and rubella vaccines are safe for children, a new Pew survey published Monday said.
Nine percent of respondents said they think such vaccines are not safe, and seven percent said they weren't sure.
The report also found that Republican (89 percent) and Democrats (87 percent) generally agree that vaccines are safe for children.
However, researchers found that there was a disparity among ages:
"Three-quarters or more in every age group say vaccines for MMR are safe. However, among adults 50 and older, 90% express this view, compared with 77% of adults 18-29 and 81% of those 30-49," the report states.
The survey comes after a measles outbreak in California sickened more than 100 people and politicians weighed in about making vaccines mandatory for kids.
Meanwhile, the Daily Camera reported over the weekend that some schools in the Boulder Valley School District have a high percentage of parents who exempt their children from vaccines:
In the Boulder Valley School District, exemptions for at least one of the required vaccines last school year ranged from a high of 82 percent at Gold Hill Elementary, a tiny mountain school, to 2 percent at Justice High, a charter school for at-risk students.
On the high end, two Boulder Valley elementary schools also had half their students exempted from at least one vaccine, according to district records.
In the neighboring St. Vrain Valley School District, St. Vrain Community Montessori had the highest exemption rate at 31 percent, followed by Lyons Elementary at 19 percent.
