INVESTED - Clinical Trial
What is the Purpose of this Study?
We are doing this study to learn if an investigational high-dose flu vaccine is able to safely reduce heart- or lung-related problems compared to the standard-dose flu vaccine because getting the flu puts people at higher risk for heart problems.

What is Involved?
If you choose to join this study, you will:
- Be randomized (like flipping a coin) to get a high dose or standard dose flu vaccine
- Have 1 in-person clinic visit for a flu vaccine at the start of the flu season (this visit will take about 90 minutes)
- Receive 3 telephone calls over the course of the flu season (about 10 minutes each) to see how you're tolerating the vaccine and how you're feeling.
- Depending on the year you start in the study, you may have the initial visit, study flu vaccine, and telephone calls described above each year for up to 3 years.
