Serum neutralizing activities against wild-type SARS-CoV-2 using the surrogate viral neutralization test (sVNT) by Euroimmun (NeutraLISA) in CV- AZ and AZ-CV groups at 4 and 10 weeks after first dose vaccination, respectively (pre-dose 2), and at 4 weeks after completion of two doses (post-dose 2). The data points are the reciprocals of the individual. Lines indicate median and bars indicate interquartile ranges. As a reference, serum neutralizing activities were compared 4 weeks after completion of two doses (post-dose 2) among homologous CV and AZ vaccines. ** indicates p< .001.
