Vaccine coverage rates among adults in the United States for most vaccines did not improve in 2013 compared with 2012, CDC researchers have found.

There were modest increases in the rate of Tdap vaccination for all adults aged 19 years and older, herpes zoster vaccination among adults aged 60 years and older and HPV vaccination among males aged 19 to 26 years. In addition, there were racial/ethnic disparities for all vaccines analyzed, with the gap increasing for Tdap and herpes zoster.
