Longitudinal analysis shows durable and broad immune memory after SARS-CoV-2 infection with persisting antibody responses and memory B and T cells

July, 2021

Highlights

  • Most recovered COVID-19 patients mount broad, durable immunity after infection
  • Neutralizing antibodies show a bi-phasic decay with half-lives >200 days
  • Spike IgG+ memory B cells increase and persist post-infection
  • Durable polyfunctional CD4 and CD8 T cells recognize distinct viral epitope regions

Origins of SARS-CoV-2: A Critical Review

July, 2021

Abstract

Since the first reports of a novel SARS-like coronavirus in December 2019 in Wuhan, China, there has been intense interest in understanding how SARS-CoV-2 emerged in the human population. Recent debate has coalesced around two competing ideas: a “laboratory escape” scenario and zoonotic emergence. Here, we critically review the current scientific evidence that may help clarify the origin of SARS-CoV-2.
