Supplemental Information

Raw data of ELISA to detect specific antibodies

Mice were immunized with PepVac, CNPs, TRE and PBS respectively. Mice sera were collected every week after immunization and used to detect the specific antibodies against inactivated FMDV by ELISA.

Raw data of lymphocyte proliferation assay

The T-lymphocyte proliferation of mice immunized with synthetic peptide vaccine, CNPs, TRE and PBS on 56 dpv. SI: OD450nm value of culture with FMDV stimulation/OD450nm value of culture without stimulation.

Raw data of cytokine levels

Splenic lymphocytes culture supernatants used in the proliferation assay were collected for evaluating IL-2, IL-4 and IFN-γ concentration. The assay were performed by the commercially available ELISA kit
