aIndirect ELISA: ID Screen® SARS‐CoV‐2 Double Antigen Multi‐species ELISA kit (ID VET, Montpellier, France). For the cut‐off values, S/P% > 60% is positive, S/P% 50−60% is suspect and < 50% is negative.
bsVNT: cPass™ SARS‐CoV‐2 Neutralization Antibody Detection Kit (GenScript Biotech, Jiangsu, China). The cut‐off values were defined as follows: positive of % inhibition > 20% and negative otherwise.
