The Million Veteran Program (MVP) is a US Department of Veterans Affairs (VA) initiative with a goal of recruiting at least one million VA healthcare beneficiaries, creating a database of genomic and phenotypic information useful for increasing understanding of health and disease (1). The sample is linked both to the VA’s extensive electronic health record (EHR) and to self-report survey information specific to the MVP study. The MVP is particularly valuable for elucidating health problems that are highly prevalent in military veterans, including alcohol use disorder (AUD) and harmful alcohol use.
