(WMBF) - Gov. Henry McMaster has announced those in Phase 1B of the COVID-19 vaccine distribution plan will be able to start making appointments on Monday, March 8. Hospitals across Horry County said theyâre preparing for an influx of new appointments. Chief Financial Officer at Conway Medical Center Brian Argo said they remain worried about supply. âThereâs more vaccine coming and you heard that from the new DHEC lead as well,â he said. âAnd we asked for more vaccine, weâve asked for over 11,000 vaccines to be delivered next week. Hopefully, that obligation can be met, we already have met our obligation of growing our workforce in order to vaccinate as many people as we can. We need the state and DHEC to meet their obligation and send us the vaccine.â
