Civilization has a tendency to flock to natural water sources. People are going to go to water, not to food. If you can go to food, and draw your own water from the earth, you're ahead of the game. Also, if you intend to "develop a vaccine" to put in a water supply in bulk, you'll observe how quickly it becomes ineffective. There are probably hundreds of true vaccines. All of them are derived from nature. As a result of that, every vaccine that exists, has a complementary resistance that has been evolved as well. Why? Because we aren't at the point in molecular biology where we can create truly effective vaccines yet. We're just borrowing from the arms race between fungi and bacteria. | ||

My safe water procedure:
1.) Mechanical Filtration: Varies in effectiveness depending on the filter diameter. This should never be your only method of making water safe, and really only helps the aesthetics of the situation, and the water only looks cleaner. This can be accomplished using any funneling system, but it is useful to have a tube of some sort that you can pack with filter material (coffee filters, cloth, charcoal bits or bits of burned wood, moss, leaves, etc., depending on your level of access). 2.) Disinfection: A couple drops of bleach should do the trick. Bleach kills organisms and destroys viruses. The chlorine is also "used" in the process, so there is a built-in rough metric for determining if there has been enough bleach added. Add a few drops, wait 30 minutes, smell. If you can't smell any bleach, add a few more drops. Repeat until you can detect any small amount of bleachy smell after 30 minute wait periods. Mechanical filtration with professional water filters usually only filter organisms, unless they specifically say they filter viruses as well (viruses are MUCH smaller than organisms). Boiling can also leave viruses intact, but tends to kill all but the most crafty organisms (as Uthgaard pointed out). As far as drinking water without any kind of treatment, try to get as close to the source spring as possible. No spring source is 100% guaranteed safe to drink, but as you get above waterfalls and other natural barriers to wildlife, there is less chance for levels of contamination likely to cause illness. | ||

Maybe I shouldn't have continued to use your incorrect comprehension of the terminology to make my point easier for you to understand, but you don't "attenuate" plants, you attenuate virii, and iodine, while it can render some virii impotent (you can't kill a virus since it isn't a living organism), isn't a vaccine. Heat can also destroy virus particles. Heat is not a vaccine either.

It's also worth noting bubonic plague is carried in force in Western US by fleas, really nothing you can do but get y. pestis vaccinated now and hope for the best later though imo. If it comes down to hunting you will be exposed to plague fleas.

Stop using wikipedia to pretend you have some grasp of biology.
If you knew anything about trophism, you'd know that fleas do not bite humans unless their native food source - rodents in this case - is extinct in the immediate environment (if no animals they would live on are around to live on, and they would otherwise starve). Humans don't get the plague from fleas. They get it from the rodents they live on. | ||
