There is no vaccine for SBV at present, although we understand a number of companies are working on one and an application has been made for marketing authorisation.
Nid oes yna frechlyn ar gyfer SBV ar y foment er ein bod yn deall bod nifer o gwmnïau yn gweithio ar ddatblygu brechlyn a bod cais wedi cael ei wneud am ganiatâd i farchnata brechlyn.
