Complete Health Indicator Report of Immunization - Influenza, Adults

Definition

Percentage of adults aged 65+ who report receiving an influenza vaccination in the past 12 months.

Numerator

Number of survey respondents aged 65+ who report receiving an influenza vaccination in the past 12 months.

Denominator

Number of survey respondents aged 65+.

Data Interpretation Issues

Starting in 2011, BRFSS protocol requires that the NJBRFS incorporate a fixed quota of interviews from cell phone respondents along with a new weighting methodology called iterative proportional fitting or "raking". The new weighting methodology incorporates additional demographic information (such as education, race, and marital status) in the weighting process. These methodological changes were implemented to account for the underrepresentation of certain demographic groups in the land line sample (which resulted in part from the increasing number of U.S. households without land line phones). Comparisons between 2011 and prior years should therefore be made with caution. (More details about these changes can be found at [http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6122a3.htm].)

Why Is This Important?

Recommended immunizations for adults aged 65 years and older include a yearly immunization against influenza (flu) and a one-time immunization against pneumococcal disease. Most of the deaths and serious illnesses caused by influenza and pneumococcal disease occur in older adults and others at increased risk for complications of these diseases because of other risk factors or medical conditions. Barriers to adult immunization include not knowing immunizations are needed, misconceptions about vaccines, and lack of recommendations from health care providers.

Healthy People Objective: Increase the percentage of children and adults who are vaccinated annually against seasonal influenza: Noninstitutionalized adults aged 65 years and older

U.S. Target: 90 percent
State Target: 67.4 percent

Other Objectives

'''Revised Healthy New Jersey 2020 Objective IMM-4''': Increase the percentage of non-institutionalized adults aged 65 years and older who are vaccinated annually against seasonal influenza to 67.4% for the total population, 72.1% among Whites, 63.8% among Blacks, 60.9% among Hispanics, and 67.8% among Asians. '''Original Healthy New Jersey 2020 Objective IMM-4''': Increase the percentage of non-institutionalized adults aged 65 years and older who are vaccinated annually against seasonal influenza to 67.4% for the total population, 72.1% among Whites, 43.6% among Blacks, and 53.9% among Hispanics.

How Are We Doing?

In 2020, 64.5% of all New Jersey adults aged 65 and older reported having received the influenza vaccination in the past 12 months. Flu vaccination is lower among Blacks (53.5%) compared to Whites (67.8%).

Data Notes

The survey question for this measure changed in 2011 to "During the past 12 months, have you had either a seasonal flu shot or a flu vaccine that was sprayed into your nose?" In previous years the question was "A flu shot is an influenza vaccine injected in your arm. During the past 12 months, have you had a seasonal flu shot?".   **No data is available for 2019. Prevalence estimates for 2011 and forward are consistent with those used to track the corresponding Healthy New Jersey 2020 objective (IMM-4).
