These studies will help our understanding of how chronic inflammatory diseases impact immunologic function and future research on mitigation strategies.', 'detailedDescription': "Our goal is to determine if an individual's level of inflammation determines their response to vaccination. The aging process and certain diseases, like type-2 diabetes, have been characterized as chronic inflammatory conditions. These individuals have higher rates of influenza disease and health care costs; hence, yearly vaccination is recommended. There is a paucity of information comparing vaccination in these high-risk groups and identifying biomarkers that can predict vaccine efficacy. The investigators hypothesize that elderly and diabetic patients have reduced responses to seasonal influenza vaccination that are inversely proportional to their level of chronic inflammation. In this pilot proposal, the investigators will examine adult and elderly diabetic and non-diabetic adults for markers of inflammation and vaccine efficacy before and after influenza vaccination. These studies will help our understanding of how chronic inflammatory diseases impact immunologic function and future research on mitigation strategies."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'In Year 1 during the 2015-16 flu season, subjects were recruited from the New Orleans metropolitan area through flyers, radio ads, internet ads, social media, and doctor referrals and vaccinated.
