Health Indicator Report of Immunization - Influenza, Adults

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. Pneumonia and influenza together constitute the tenth leading cause of death (2009) among New Jersey residents; over 80% of these deaths occur in persons aged 65 and over.

Influenza Vaccination in the Past 12 Months by County, New Jersey, 2015


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

Data Interpretation Issues

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?"

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: To be determined

Other Objectives

Healthy New Jersey 2010 Objective 3G-4: Increase the percentage of persons 65 and older who have received influenza vaccinations in the previous 12 months to 70%. 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.

How Are We Doing?

In 2013, 57% 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 (48.9%), Hispanics (56.1%), and Asians (63.5%) compared to Whites (58.6%).

What Is Being Done?

Since 1998, NJDOH has played a lead role in a statewide adult immunization campaign, collaborating with organizations such as the New Jersey Quality Improvement Organization (NJ-QIO), local health agencies, the provider community, long-term care facilities and hospitals to increase the influenza and pneumococcal vaccination rates among seniors statewide. NJDOH has adopted regulations requiring nursing homes to offer these two immunizations to all residents, and for hospitals to offer them to seniors who have been admitted for treatment. These measures, in combination with continued education and outreach, should improve coverage rates by 2010. The goal of the New Jersey State Strategic Plan on Aging, October 1, 2005-Oct 30, 2008 is to implement evidence-based health promotion and disease prevention programs including influenza vaccination among seniors.
