A new study shows a lot of adults are missing key vaccinations that could protect from serious, life-threatening illnesses. So while you may have gotten a flu shot this winter, there are other vaccinations out there that are just as important for adults to get.

The Centers for Disease Control and Prevention analyzed data from both a 2011 and 2012 National Health Interview Survey. It found vaccine coverage is "depressingly low."  (Via WABC)

Those included vaccines for pneumonia, tetanus, Tdap — which prevents whooping cough — hepatitis A and B, herpes zoster and HPV. (Via Centers for Disease Control and Prevention)

There are a number of reasons people skip out on vaccinations, according to one researcher.

"'Mythology surrounding vaccination is the greatest obstacle. In spite of all the press about the rise of whooping cough, for instance, patients still may refuse vaccination.' Those 'myths' include fears that vaccines might cause autism, a concern that has been widely discredited, or lead to illness or severe reactions." (Via HealthDay News)

Financial issues were also reportedly one cause, and there was a wide racial gap with whites more likely to be up-to-date than blacks or Hispanics.

"Luckily, there's something patients and doctors can do about it. Next time you see your doctors, take a moment to review your immunization history so you can get what you truly need." (Via WDAZ)
