If you think vaccines are kids stuff, you're not alone.  According to the Centers for Disease Control, most American adults are not getting the shots they need to stay healthy.  

Although parents worry about getting children immunized, only a small number  of adults get all recommended inoculations.  The CDC says the average adult in the US should be protected from flu, measles, mumps, rubella, hepatitis a and b, whooping cough and tetanus. 

Younger adults should be getting a meningitis shot and women ages 18-26, the hpv vaccines, that protects against cervical cancer.  Older folks should also get flu and pneumonia shots and a vaccine for shingles.
