Researchers at Stanford want to understand how COVID-19 affects your body's ability to build immunity from the flu vaccine. They're comparing people who have had COVID-19—including those with lingering symptoms, obesity, or diabetes—with people who haven't had COVID-19. By measuring your immune response over time through blood tests, they hope to learn whether COVID-19 changes how well the flu vaccine protects you.
Some people who've had COVID-19 may have weakened immune responses or ongoing health conditions that could affect how well vaccines work. Understanding this connection will help doctors better protect people who have had COVID-19 from getting the flu.

You would visit the research clinic multiple times over several months to have blood samples drawn. These blood tests measure how well your immune system responds to the flu vaccine over time. The study compares your immune response to that of people without a COVID-19 history, helping researchers understand whether and how COVID-19 affects your body's ability to benefit from the flu vaccine.
