Using information national health interview studies from 2011 and 2012, the CDC says while many adults get the flu vaccine, they are missing vaccines for pneumonia, tetanus, hepatitis A and B, herpes zoster, and HPV.
One reason people aren't getting their vaccines is the belief that vaccines cause autism or illness, which is based on discredited research. There is no evidence that vaccines are linked to autism. Researchers found some people could not afford vaccines. They also found that whites were more likely to be vaccinated than blacks and Hispanics.
The CDC recommends people check with their doctor about their vaccination history to see if they are up-to-date.
