We designed a bivalent vaccine for HFMD based on chimpanzee adenovirus serotype 68.
Epitopes PEP71 and sSP70 were inserted into HVR1 and HVR2, respectively, of the hexon.
Modelling studies revealed that the epitopes were well presented on the virion surface.
Vaccination conferred protection against CA16 and EV71 to suckling mice.
