Number of HFMD cases in I3 changes under different EV71 and bivalent vaccine coverage rates. A-E: 0, 10, 30, 50, 80% EV71 vaccine coverage combined with 0, 10, 30, 50, 80, 100% Bivalent vaccine coverage, respectively. I3 indicates the number of EV71 or CVA16 HFMD \( \left({\mathrm{I}}_{\mathrm{h}}^{\mathrm{ec}}\right) \) / only EV71- HFMD \( \left({\mathrm{I}}_{\mathrm{h}}^{\mathrm{e}}\right) \), based on different types of vaccines
