The reason computer viruses are called viruses is NOT because they are
manmade, but because of how they work; their behavior is somewhat like
that of biological viruses.

The first vaccination developed was for the smallpox virus. 

Not sure, but I suspect there are more vaccinations available against
viruses  than against bacteria. But the basic idea is the same in any
case. Vaccines are targeted against some particular feature of the
virus or bacterium -- or protozoan or even human cell.
