How aging affects the immune response to the flu vaccine in older adults

Official title: Impact of preexisting immune profile in elderly on influenza vaccine response

Funded at Louis Stokes Cleveland VA Medical Center · NIH-10950302 · Data updated 2026-11-12

This study is looking at how the immune systems of older adults work before getting the flu shot to see if it helps us understand why some people respond better to the vaccine than others, with the hope of making the flu vaccine more effective for seniors.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals aged 65 and older who are preparing to receive the seasonal influenza vaccine.

Less likely to help

Patients younger than 65 years old or those who do not plan to receive the influenza vaccine may not benefit from this research.

What this research studies

This research investigates how the immune profiles of elderly individuals influence their response to the influenza vaccine. It focuses on understanding the interactions between different immune cells before vaccination and how these interactions may affect the effectiveness of the vaccine. By examining blood samples from both elderly and younger participants, the study aims to identify specific immune characteristics that correlate with better vaccine responses. The goal is to enhance vaccine efficacy in older adults, who are at higher risk for severe influenza outcomes.

Why it matters

Potential benefit: If successful, this research could lead to improved influenza vaccine strategies for older adults, enhancing their protection against the virus.

How similar studies have gone: Previous research has shown that understanding immune responses in older adults can lead to improved vaccination strategies, indicating potential success for this approach.
