Riverside County still in ‘planning stage' of vaccinating homeless population Natalia Gurevich Every day, Mark McGowan pulls a handful of names from a list of about 230 homeless people living at the Coachella Valley Rescue Mission and around its campus. The supervisor has to receive word from the shelter's in-house medical provider SAC Health System that there are available vaccines before he springs into action. Once he does, he and a staff member pile into a van along with chosen clients and drive to the nearby Loma Linda University Children’s Health in Indio, where the vaccines are administered to some of the Coachella Valley’s most vulnerable individuals. Thirty days later, they’ll get the second dose.
