The effectiveness of immune memory in recognizing SARS-CoV-2 variants after mRNA vaccination
In this study, teams from Henri-Mondor AP-HP Hospital and University Paris-Est Créteil, Inserm, the CNRS, Université de Paris (in the Institut Necker-Enfants Malades) and the Institut Pasteur investigated the ability of the immune memory generated after mRNA vaccination to recognize and neutralize SARS-CoV-2 variants. Their results show that individuals vaccinated with a messenger RNA vaccine against SARS-CoV-2 develop defenses against the Beta and Delta variants. Their immune system produces memory cells capable of recognizing and neutralizing variants of concern. The results of this study were published on September 20, 2021 in the journal Immunity.
