Abstract
The coronavirus disease 2019 (COVID-19) pandemic demonstrated how rapidly vaccines and monoclonal antibodies (mAbs) could be deployed when the field is prepared to respond to a novel virus, serving as proof of concept that the prototype pathogen approach is feasible. This success was built upon decades of foundational research, including the characterization of protective antigens and coronavirus immunity leading to the development and validation of a generalizable vaccine approach for multiple coronaviruses. For other virus families of pandemic concern, the field is less prepared. The articles in this special issue have highlighted research gaps that need to be addressed to accelerate the development of effective vaccines and mAbs, to identify generalizable vaccine and mAb strategies, and to increase preparedness against other pandemic threats. Successful implementation of the prototype pathogen approach will require a systematic, multidisciplinary, coordinated approach with expertise and crosstalk among researchers of different virus families.
