The FSG Global Health Impact Area regularly organizes training sessions, in which guest speakers are invited to share their perspectives on some of the most pressing health issues. Last week, we were fortunate enough to have Dr. Heidi Larson, Senior Lecturer at the London School of Hygiene and Tropical Medicine and Advisor to FSG’s Global Health Impact Area, speak to us about her work on vaccines. Specifically, she talked about her most recent Lancet article on the topic titled addressing the vaccine confidence gap.
