Association of Influenza Vaccination Coverage in Younger Adults With Influenza-Related Illness in the Elderly.

ABSTRACT:

Background

Older adults have the highest influenza-related morbidity and mortality risk, but the influenza vaccine is less effective in the elderly. It is unknown whether influenza vaccination of nonelderly adults confers additional disease protection on the elderly population.

Methods

We examined the association between county-wide influenza vaccination coverage among 520 229 younger adults (aged 18-64 years) in the Behavioral Risk Factors Surveillance System Survey and illnesses related to influenza in 3 317 709 elderly Medicare beneficiaries aged ≥65 years, between 2002 and 2010 (13 267 786 person-years). Results were stratified by documented receipt of a seasonal influenza vaccine in each Medicare beneficiary.

Results

Increases in county-wide vaccine coverage amon
