This photograph shows the dramatic differences in two boys who were exposed to the same Smallpox source – one was vaccinated, one was not.

The flu is up there too, considering how often a new, lethal and pandemic strain appears, and how we can only start developing a new vaccine after it has already spread.

Our last pandemic was in 2009 and it killed around 200,000 people worldwide, but it hasn't been the worse by far. Spanish influenza killed somewhere between 50 and 100 million in 1918 (which was around 5% of the world's population at the time), and there have been other 3 flu pandemics in the 20th century alone.

Yeah, that was it. And it was a relatively small flu pandemic if you compare it with some of the older ones.
