Americans remain steadfast in their belief in the overall value of childhood vaccines, with no change over the last four years in the large majority who say the benefits of childhood vaccines for measles, mumps and rubella (MMR) outweigh the risks, according to a new Pew Research Center survey.
Still, the survey finds that alongside broad support for childhood vaccines there are signs of some concern – especially among those closest to the decision-making process of vaccinating children. Parents see the risks of MMR vaccines as a bit higher than other Americans, and about half of those with a young child ages 0 to 4 say the statement “I worry that not all of the childhood vaccines are necessary” describes their views at least somewhat well. Concerns tend to be higher among mothers than fathers: Roughly half of mothers with a child under 18 rate the risk of side effects from MMR vaccines as medium or high – 15 percentage points higher than the share of fathers who say this.
