Since the coronavirus reached Orange County in March, Hoag Hospital has remained on the frontlines, helping those infected with coronavirus. The hospital cared for the first Orange County COVID-19 patient back in January, says Dr. Philip Robinson, medical director of infection prevention at Hoag and principal investigator of the vaccine trial. Now, under a collaboration between NantKwest, Inc. and ImmunityBio, Hoag will serve as the trial site with a goal of examining the safety, side effects, and immune system response of the two-dose prospective vaccine.
