WellMed administering 9,000 doses this week by appointment to residents in south, west San Antonio Toll-free line receives 170,000+ phone calls for available COVID-19 vaccine doses, officials say Tags: SAN ANTONIO – Unlike the City of San Antonio’s mass vaccination clinic at the Alamodome, which required registration online or by calling 311, two other clinics on the South Side and West Side of San Antonio operated by using a toll-free number. WellMed -- in partnership with City Council Districts 3, 4 and 7 -- said that the toll-free number (833-968-1745) was quickly jammed as community members attempted to make an appointment. Rebecca Viagran, who represents District 3, said they received more than 170,000 phone calls from people who wanted one of the 9,000 doses available.
