To assess the protection levels at 1-year post-infection, we measured the neutralization capacity of serum samples collected at 1–2 months or 10–12 months after infection using a pseudovirus neutralization assay (PNA) based on the neutralization of WT (Wuhan-Hu-1) SARS-CoV-2 spike pseudotyped lentivirus-mediated transfection of a luciferase reporter in replication-deficient 293T-ACE2 cells.27 Two serum samples were not analyzed due to insufficient volume for PNA. This evidence concerns the gene ACE2 and infection.
