The test detects antibodies against the nucleocapsid (N) protein of the SARS-CoV-2 virus, while vaccines elicit antibodies to the spike (S) protein of the virus particle (1). This Roche assay targets total antibodies to the SARS-CoV-2 spike (S) protein which is also the antigenic target of the vaccines currently available in the United States. A better understanding of the anti-SARS-CoV-2 immune response is necessary to finely evaluate commercial serological assays but also to predict protection against reinfection and to help the development of vaccines. Antibodies generated against SARS-CoV-2 during the first COVID-19 wave had reduced immunoreactivity and neutralization potency to emerging Spike variants and VOC.
