(MCT) — LOS ANGELES — Researchers at the U.S. Centers for Disease Control and Prevention said Tuesday that vaccination coverage levels in U.S. adults were “unacceptably low,” and that public health workers need to do more to make sure adults got immunizations to protect them from diseases including whooping cough, shingles and pneumonia.

The team, writing in the CDC’s Morbidity and Mortality Weekly Report, updated statistics on vaccine coverage for those diseases as well as cervical cancer, hepatitis A and B and other preventable illnesses.
