Study Arms:
- experimental group (Type: EXPERIMENTAL): 378 subjects from the experimental group will be simultaneously administrated with one dose of EV71 vaccine (0.5 ml) and one dose of influenza vaccine (0.25 ml). One month later, they are going to receive a second dose of EV71 vaccine and influenza vaccine, simultaneously.
- control group A (Type: ACTIVE_COMPARATOR): 378 subjects from the control group A will be only administrated with two doses of EV71 vaccine (0.5 ml) (1 month apart).
- control group B (Type: ACTIVE_COMPARATOR): 378 subjects from the control group B will be only administrated with two doses of influenza vaccine (0.25 ml) (1 month apart).

Based on this trial design, predict the completion outcome and termination type (if applicable).
