On November 18, 2019, the Gladstone Institutes and UCSF hosted Dr. Antonio Lanzavecchia, who presented a seminar entitled “Dissecting human antibody responses: useful, basic and surprising findings”. Dr. Lanzavecchia gave a wonderful talk and met with both trainees and faculty throughout his visit. This was the first seminar in the new Infectious Disease and Human Health Series, which is organized by GIVI, HPMI, QBI and BioFulcrum II.
