Influenza Immunization among Adults Aged 65 and Over by County, New Jersey, 2018-2021

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.

Definition

Data Notes

Data Issues

Data from the New Jersey Behavioral Risk Factor Survey are intended to be representative of all non-institutionalized adult residents of New Jersey. Due to resource issues, however, adults with limited personal access to phone service or limited command of either English or Spanish are not represented. As with all surveys, also, some error results from nonresponse (e.g., refusal to participate in the survey or to answer specific questions), and faulty measurement (e.g., responses affected by social desirability or recall error). Data collection procedures intended to minimize such errors include the use of strict calling protocols, good questionnaire design, standardization of interviewer behavior, interviewer training, and frequent, on-site interviewer monitoring and supervision. Statistical weighting procedures are also used to minimize the potential impact of disproportionate representation of demographic subgroups defined in terms of age, sex, race, ethnicity, education level, marital status, home ownership, and county of residence.
