Older adults' flu vaccines: comparing high-dose and MF59-adjuvanted vaccines

Official title: Systems investigation of vaccine responses in aging and frailty

Funded at Yale University · NIH-11357635 · Data updated 2026-11-12

Researchers will compare how two flu vaccines perform in older adults living in nursing homes or receiving home-based care, to see which triggers a stronger immune response.

Who could benefit from this research

Could help

Older adults (65+) in nursing homes or homebound primary care settings who are receiving influenza vaccination.

Less likely to help

Healthy younger adults without aging-related frailty or those not receiving vaccines for study purposes may not directly benefit.

What this research studies

This project will enroll adults over 65 living in nursing homes or receiving home-based care, plus a younger adult comparison group. Participants receive either the high-dose unadjuvanted flu vaccine or the MF59-adjuvanted standard-dose vaccine. The study will examine immune, gene expression, and protein changes after vaccination to understand why responses differ by age. This builds on established collaborations with Yale geriatrics experts and care facilities. Findings could guide better vaccination choices for older adults at risk from influenza.

Why it matters

Potential benefit: If successful, the work could inform which vaccine provides stronger protection for older adults, potentially reducing flu-related illness and hospitalizations.

How similar studies have gone: Prior research has shown age-related differences in vaccine responses; this study extends known work by directly comparing two vaccines in a frail elderly population.
