Although 71% of adults surveyed in the Walgreens Immunization Index believed that staying current on immunizations was very important to maintaining good health, survey data also revealed several trends indicating disconnect between participant perception and behavior regarding immunizations.
The Walgreens Immunization Index was a telephone survey conducted in August and September 2012 among a nationally representative sample of 600 U.S. adults older than 18 years; participants were balanced to match U.S. Census data for gender and age groups. In addition to measuring immunization behaviors and knowledge, the survey assessed participants' response to information from health care providers, news media, and other external sources.
The survey results showed that 89% of U.S. adults believed that vaccinations offer protection against viruses and preventable diseases, but greater than 40% were unaware of the immunizations they might need or when they last received vaccines routinely recommended by CDC.

Other findings from the survey included the following:
