Soluble RHDV-VP60 protein was expressed in Escherichia coli by a pSMK vector containing a SUMO tag.
The VP60 protein of RHDV has self-assembled into VLPs after the cleavage of the SUMO tag.
RHDV specific responses were obviously induced in rabbits by RHDV-VLPs.
VLPs-based RHDV vaccine can be used as a promising RHDV vaccine candidate.
