TL;DR: While most of individuals develop neutralizing antibodies within two weeks of infection, the level ofneutralizing activity is significantly decreased over time, highlighting the importance of studying the persistence of neutralizing activity upon natural SARS-CoV-2 infection.
Journal ArticleDOI
Decline of Humoral Responses against SARS-CoV-2 Spike in Convalescent Individuals.
Guillaume Beaudoin-Bussières,Annemarie Laumaea,Sai Priya Anand,Jérémie Prévost,Romain Gasser,Guillaume Goyette,Halima Medjahed,Josée Perreault,Tony Tremblay,Antoine Lewin,Laurie Gokool,Chantal Morrisseau,Philippe Bégin,Cécile Tremblay,Valérie Martel-Laferrière,Daniel Kaufmann,Jonathan Richard,Renée Bazin,Andrés Finzi,Andrés Finzi +19 more
TL;DR: How the humoral responses against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Spike glycoprotein, including neutralization, evolve over time is evaluated to suggest that plasma from convalescent donors should be recovered rapidly after resolution of symptoms.
Journal ArticleDOI
A single dose of the SARS-CoV-2 vaccine BNT162b2 elicits Fc-mediated antibody effector functions and T cell responses.

TL;DR: In this article, a single dose of the BNT162b2 mRNA vaccine for SARS-CoV-2 was found to be up to 90% effective starting 14 days post-administration.
Journal ArticleDOI
Real-Time Conformational Dynamics of SARS-CoV-2 Spikes on Virus Particles.

TL;DR: Conformational preferences observed upon expsoure to convalescent plasma or antibodies suggest mechanisms of neutralization involving either competition with hACE2 for binding to the receptor-binding domain (RBD) or allosteric interference with conformational changes required for entry.
Journal ArticleDOI
Longitudinal analysis of humoral immunity against SARS-CoV-2 Spike in convalescent individuals up to 8 months post-symptom onset.

TL;DR: In this article, the presence of SARS-CoV-2-specific memory B cells in convalescent individuals was evaluated using a longitudinal assessment of humoral immune responses.
