The share of Americans who say it's important to vaccinate children has fallen from 94% to 84% since 2001, according to a new Gallup survey.
The big picture: Misinformation about vaccines is still rampant — 46% of those polled said they weren't sure whether vaccines cause autism, despite numerous studies showing no apparent link.
Methodology: Results are based on telephone interviews conducted December 2-15, 2019 with a random sample of –1,025—adults, ages 18+, living in all 50 U.S. states and the District of Columbia. The margin of sampling error is ±4 percentage points at the 95% confidence level.
