CATTLE VACCINE IS WHAT IS NEEDED
Western Daily Press. . Features/Letters
I rather think Chris Rundle has missed the point about bovine TB ("Excuses, excuses, excuses", Western Daily Press, December 12).
It is not a vaccine for the badger that is needed, but cattle. TB is also carried by deer, so what a task that would be.
Cattle can be restrained in a crush which are now used by farmers.
I wish farmers would put pressure on Defra for a vaccine. It has been promised for years - I think the figure is still 10 years.

Editor, . The input of well-intended animal lovers like Pamela Dean is not only naive, but foolhardy in the extreme. Her letter once again exposes her ignorance of the complexities of producing any vaccine; let alone one for Mycobacterium-bovis. . . . . Research will tell the thoughtful that the efficacy of Mycobacterium bovis bacillus Calmette-Guerin (BCG) vaccine against pulmonary tuberculosis (TB) varies enormously in different populations. The prevailing hypothesis attributes this variation to interactions between the vaccine and mycobacteria common in the environment, but the precise mechanism has so far not been clarified. . This is in humans! . Even before anyone begins to seriously try to find one for cattle. . . There is no alternative to a Badger cull in the foreseeable future.
