There Probably Aren't Different Strains of SARS-CoV-2 (Yet)

The video discusses the concept of virus strains, focusing on SARS-CoV-2 and its mutations. It explains the difference between strains and lineages, highlighting that SARS-CoV-2 mutates slower than the flu. The video explores how genetic sequencing helps track virus spread and the potential impact of mutations on virulence. It also addresses the scientific debate around these mutations and the role of preprints in research dissemination. The conclusion emphasizes that while distinct lineages exist, they do not yet qualify as new strains, which is crucial for vaccine development.
