One Health security lessons from a year-long webinar series on international COVID-19 response.

Following the principles outlined by the Global Outbreak Alert and Response Network, the Federal Bureau of Investigation's International Biosecurity and Prevention Forum, the European Commission's Joint Research Centre, and the Middlebury Institute of International Studies' James Martin Center for Nonproliferation Studies cohosted a webinar series from April 2020 to January 2021 on COVID-19 management across Africa, Europe, and North America. We provide here an overview of the webinar series and discuss how lessons learned during the COVID-19 pandemic and debated during the webinars can be used to bridge One Health with biological threat-driven health security. This report can be used to inform recommendations for future One Health security approaches to strengthen global capacity and multidisciplinary cooperation.
