The data represent the number of responders/number of tested individuals (the percentage of responders is given in parentheses) and the antibody levels expressed as mean of OD index ± SD. The Student's t-test was used to analyse the differences in mean values, the Chi-square test was used to analyse the difference in prevalence of positive responses. |
