Neutralization capacity of plasma (n = 186) form HCWs against coronaviruses spikes pseudotyped viruses. (a) Neutralisation profile of plasma against SARS-CoV-2 wildtype, SARS-CoV-1, MERS-CoV, HCoV-229E, and HCoV-NL63. (b) Comparison of neutralization titers between SARS-CoV-2 exposed-vaccinated (indicated by solid circles symbols) and exposed-unvaccinated (open diamond symbols), and (c) between SARS-CoV-2 seropositive (circle symbols) and seronegative groups (triangle symbols). The horizontal dotted line indicates the lowest limit of dilution tested (1:40). Statistical significance was determined using the Mann–Whitney-U rank test and P value < 0.05 was considered significant, (d) Spearman's correlation between neutralization titers for coronaviruses and the total anti-SARS-CoV-2 RBD binding antibodies quantified by ELISA. WT wild-type, NT neutralization titer.
