The 48th Medical Group conducted its first inoculations of healthcare workers with the COVID-19 vaccine at Royal Air Force Lakenheath, England, Dec. 29, 2020. Initial vaccines will be limited to healthcare workers and first responders to assess the process, and will be used to plan an expanded distribution phase, where each service will request and administer the vaccine through a Defense Department-wide phased vaccination approach.
