In our area, we have a large number of people who have come into the coutry illeagally and of course have not been vaccinated. In fact one of our local hospitals has had a whole group with active TB. The health department wants to track down who these people have been in contact with but of course they wont tell.
The good news is that many of the companies that made vaccines have be sued into nonexistence. If these recurrences of disease continue I expect that the remaining companies will be sued for not making enough vaccine available. After all, the media that started it will try to sensationalize that it is "Big Phama" that is to blame.
