The National Law Review selected von Briesen's COVID-19 Task Force as a Go-To Thought Leader for 2021 for the group’s coverage of COVID-19 vaccine mandates. As the coronavirus vaccine became widely available, many employers debated whether to require vaccines for their employees or if such mandates were legal. In particular, the group’s coverage of OSHA and CMS guidance on federal vaccine mandates provided must-read insights for employers navigating compliance with the rules.  Authors who contributed insights into this area include John A. Rubin, Craig T. Papka, Robert J. Simandl and Audrey R. Merkel.
