Bison in Yellowstone National Park are getting the brucellosis disease from escaping the park or Bison coming in from outside the park. The human form of the disease is undulant fever but it is no longer a public health threat, however Elks can still get the disease. About half of the Yellowstone Bison test positive for the exposure to the disease. People have come up with different ideas on how to solve this problem. I think that the best solution is to inject all the bison with the brucellosis vaccine. Sure it would be a lot of work to inject every single bison in the park with the brucellosis vaccine, but if it keeps the bison from getting the disease then I’m all for it! Another good thing about it is that if the bison do wander out of the park then they will have the vaccine and nothing, or no one will be at risk of getting the disease. If the bison wander of out of the park then people may end up hunting the bison. Now, there are some bad things, if they do choose to try to inject all the bison, they’ll have to pay for vaccines for every single bison. It would also be a pain because some bison may end up wandering into the park, who may possibly have the disease. Then they would have to check on the bison every so often to see if any of them need the vaccine. So, those are all the good things and bad things of vaccinating all of the bison.
