Almost one in 10 Americans believe vaccines for diseases including measles, mumps and rubella are not safe for healthy children, indicating a significant number of Americans have misconceptions about the danger of vaccinations.
Skepticism with vaccines crosses party and demographic lines, according to the Pew Research Center study released Monday, with about 5% of Republicans and 9% of Democrats saying vaccines are unsafe, and 11% of men and 8% of women saying the same.
