Indicator Report - Immunization - Influenza, Adults
Why Is This Important?Influenza, or flu, is an acute viral infection involving the respiratory tract that can occur in epidemics or pandemics. Influenza can cause a person, especially older persons, to be more susceptible to bacterial pneumonia.
Data NotesIn 2011, the BRFSS changed its methodology from a landline only sample and weighting based on post-stratification to a landline/cell phone sample and raking as the weighting methodology. The 2011-2012 data on this graph are based on the new methodology (landline/cell phone sample; raking).
Due to changes in both sampling and the question format, data for 2011-2012 should be interpreted with caution compared to previous years.
U.S. data are the average for all states and the District of Columbia; they do not include the U.S. territories.
These rates are crude rates, not age-adjusted, given that the Healthy People 2020 Objective is based on crude rates.
