In 8 May 1980, the World Health Organisation declared that "the world and its peoples have won freedom from smallpox." Through decades of intense vaccination, this once fatal disease had been wiped out. It was a singular victory and having won it, countries around the world discontinued the vaccination programmes. After all, why protect against a disease that no longer exists (save in a few isolated stocks)? Unfortunately, this is not a rhetorical question. The smallpox vaccine did more than protect against smallpox. It also reduced the risk of contracting a related illness called monkeypox, which produces the same combination of scabby bumps and fever. It's milder than smallpox but it's still a serious affliction. In Africa, where monkeypox originates from, it kills anywhere from 1-10% of those who are infected. And more and more people are becoming infected. Anne Rimoin from the University of California, Los Angeles compared data on the virus in the Democratic Republic of Congo over the last three decades. She found that, during those years, monkeypox has become 20 times more common in humans. In one particular area, 72 people out of every million were infected each year between 1981 and 1986. Between 2005 and 2007, that figure rose to 1442 per million.

Nobody in the right mind would say wiping out smallpox was wrong but, as the link attests, when A "covers" B removing A will "uncover" B. See it all the time in medical history.
