Fort Jackson expands the number of people eligible for COVID vaccine, similar to SC Noah Feit, The State (Columbia, S.C.) Mar. 3—Fort Jackson is expanding the group of people who can receive the first dose of the COVID-19 vaccine on post. More community members of the U.S. Army installation in the Columbia area can schedule an appointment to get the shot, Fort Jackson officials said Wednesday in a news release. The process started Tuesday, the same day that Gov. Henry McMaster said South Carolina will transition into Phase 1b of its vaccine rollout. That effort to immunize the state's population against the coronavirus will begin next Monday.
