SARS-CoV-2 mRNA vaccines elicit higher levels of antibodies compared to natural infection

Researchers from the US recently characterized the scale and specificity of SARS-CoV-2 spike-reactive antibodies from 23 participants who received SARS-CoV-2 mRNA vaccines and 10 acutely infected health care workers. They found that primary mRNA vaccination and infection elicited S1- and S2-reactive antibodies, while secondary mRNA vaccination elicited mostly S1 antibodies.

Using a new public antibody to understand SARS-CoV-2 neutralization

SARS-CoV-2 infects host cells by binding to the angiotensin convertase 2 receptor (ACE2) on the cell surface through its trimeric spike (S) protein. SARS-CoV enters host human cells through endosomes, while SARS-CoV-2 enters through the cell surface and endosomes. The present study published in the journal “Cell Reports” aimed to understand the mechanisms of SARS-CoV-2 antibody neutralization to facilitate the development of therapeutic interventions for COVID-19.

Immune response to SARS-CoV-2 variants of concern after natural infection or vaccination

A recent review paper published in the MDPI's journal Viruses highlights how available vaccines may be effective in protecting individuals against severe forms of coronavirus disease 2019 (COVID-19), but the protection against infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its transmission to others may be reduced – with consequences for community protection and herd immunity.
