VA SHIELD interacts with multiple VA programs and other entities (Figure). For example, Surveillance Platform for Enteric and Respiratory Infectious Organisms at United States Veterans Affairs Medical Centers (SUPERNOVA) is a network of 5 VA medical centers supported by the Centers for Disease Control and Prevention.4 Its initial goal was to perform surveillance for acute gastroenteritis. In 2020, SUPERNOVA shifted to conduct surveillance for COVID-19 variants among veterans.5 VA SHIELD also interacts with VHA genomic surveillance and sequencing programs: the VA Sequencing Collaborations United for Research and Epidemiology (SeqCURE) and VA Sequencing for Research Clinical and Epidemiology (SeqFORCE), described by Krishnan and colleagues.6
Working Groups
To encourage research projects that use biospecimens, VA SHIELD developed content-oriented research working groups. The goal is to inspire collaborations between VA scientists and prevent redundant or overlapping projects. Currently working groups are focused on long COVID, and COVID-19 neurology, pathogen host response, epidemiology and sequencing, cancer and cancer biomarkers, antimicrobial resistance, and vector-borne diseases. Working groups meet regularly to discuss projects and report progress. Working groups also may consider samples that might benefit VA health research and identify potential veteran populations for future research. Working groups connect VA SHIELD and investigators and guide the collection and use of resources.
