Fig. 2: Overall Vaccine-hesitant attitudes scores stratified by SIV type preferences and the three time periods based on the whole sample (N = 1302).

“SIV”: seasonal influenza vaccine; “IIV”: inactivated influenza vaccine; “LAIV”: live attenuated influenza vaccine. The VH score is determined by calculating the mean of the IIV group (Blue) and the LAIV group (Red), stratified by time periods. One-way Wilcoxon signed-rank tests were employed to test differences between groups for each SIV type preference and time point. The statistical details for the mean, median, and IQR can be found in Supplementary Table 2. P-values have undergone Bonferroni correction to account for multiple comparisons, denoted as follows: ^* for P < 0.01, ^** for P < 0.05, and ^*** for P < 0.001. Insignificant comparisons (P > 0.05) were not shown.
