DOD Tracking COVID Vaccinations with New Electronic Health Record System Vonkara1/istockphoto email The Defense Department’s relatively new electronic health record system—Military Health System, or MHS, GENESIS—is being used to track vaccinations against COVID-19, building a database of inoculations and ensuring the process is fast and safe for servicemembers. “Throughout 2020, like most of Americans, the entire Military Health System has faced very unique challenges,” Brig. Gen. Ned Appenzeller, assistant director for combat support at the Defense Health Agency, told reporters in November as the launch schedule resumed. “However, even with those challenges, I think we’re still on track to fully deploy Genesis by the end of ’23.”
