Transmission electron micrograph of a<unk> . A<unk> , also known as a pan<unk><unk> , is a<unk><unk>  that is effective against all<unk>  strains. A<unk><unk>  would provide protection against<unk>  strains that have caused disease in humans, such as SARS-CoV-2 (including all its variants), while also providing protection against future<unk>  strains. Such a<unk>  has been proposed to prevent or mitigate future<unk>  epidemics and pandemics. Efforts to develop a<unk>  began in early 2020. In December 2021, NIAID director Anthony Fauci, virologist Jeffery K. Taubenberger, and David M. Morens endorsed the development of durable<unk> s and advocated in favor of "an international collaborative effort to extensively sample<unk> es from bats as well as wild and farmed animals to help understand the full 'universe' of existing and emerging<unk> es", including already identified animal<unk> es with pandemic potential. In March 2022, the White House released the "National COVID-19 Preparedness Plan", which, in part, discusses plans to "accelerate research and development toward a single COVID<unk>  that protects against SARS-CoV-2 and all its variants, as well as previous SARS-origin viruses".
