And as for vaccines against the big baccies, as I was gesticulating at, here's a few I found at a glance: typhoid, tetanus, pneumococcus, meningococcus B, cholera, and fucking anthrax, of all things...

So sure, I was slightly off, when it comes to antiviral vaccines (apparently I need to study more human toxicology, instead of animals, lol...), but my general point is, I think, still fairly valid. But I admit you did find a flaw in my logic, so I stand corrected on that much.
