The scientific basis for the Badger BCG vaccine is questionable
A recent critical assessment of the scientific basis for the Badger BCG vaccine reveals serious shortcomings.
Although the vaccine has been shown to provide some protection against experimental challenge it fails to protect against infection and all vaccinated animals shed M.bovis post challenge. Furthermore it has no proven efficacy against bovine TB in the field. The likelihood therefore of the vaccine giving protection in the face of the massive infection out there in the badger population is therefore highly improbable. The vaccine has only a Limited Marketing Authority. For more information please see our letter to the AHVLA questioning the efficacy and safety of the Badger BCG vaccine (2014b).
