Airman 1st Class James Gehne, 375th Civil Engineer Squadron firefighter, receives the first COVID-19 inoculation on Scott Air Force Base, Ill., Jan 6, 2021. Vaccines combating COVID-19 use inactivated virus genetics to strengthen the immunity properties of the receiver while still making it impossible to contract COVID-19 from the inoculation.
