But despite these substantial health benefits, attitudes toward childhood vaccinations have shifted, and they are increasingly tough sell. A Gallup poll published recently found that just 40% of Americans think it’s “extremely important” for children to get vaccinated, down from about 64% in 2001. Reaching families at or below the poverty line can be even more difficult.

CDC officials pointed to a lack of confidence and a lack of access to vaccines as key reasons for the lower rates among VFC eligible children.
