For this reason, YURVAC RHD vaccine has been tested in the presence and in the absence of maternally derived antibodies (MDA) against RHDV2. The aim of this study was to demonstrate to what extent MDAs against RHDV2 could have an impact on the efficacy of YURVAC RHD vaccine in 30-days-old rabbits by means of a challenge. 

The results confirmed that RHD MDAs do not interfere with the efficacy of YURVAC RHD.
