Updated: 1:46 PM EDT May 21, 2021 COLUMBIA, S.C. — Because additional COVID-19 vaccination sites have opened in the community, and there has been reduced demand from the public, Prisma Health is making changes to its vaccination sites. According to the healthcare system, they have administered nearly 400,000 vaccines. Vaccinations have been made available at certain physician offices within Prisma, based on pharmacists and clinical staff. Prisma Health is hoping to expand into more physicians' offices soon. Rick Scott, chair of Prisma Health vaccine task force, said, “We are very proud to have begun the vaccination efforts on the first day vaccine was available and have vaccinated more South Carolinians than any other organization. We continue our commitment to getting shots in arms through our vaccination sites, mobile units and now our primary care offices.
