IW,
My point is, mankind may be harming his natural ability to evolve a better, more perfect immune system by applying these quick fixes. Scientists who believe in evolution should have faith enough in it to trust that natural selection is the better way to go rather than thwarting this process by using immunization which saves the individual but does not produce a better, stronger species.
Humans are far more complex, and evolve slower, than the microbes that attack us. Remember that evolution works equally well for all organisms, so the arms race between predator and prey can go on for millions of years. Microbes have come darned near wiping us out earlier, and it's far from impossible that they can still get the upper hand one day. Our first and last line of defence if and when that happens is modern science.
Scientists who know about evolution knows it is a natural force with as little moral or foresight as gravity. Evolution works, but not to make our lives better. It simply treats us as survival machines for our genes. It doesn't work for the best of the individual nor for the best of the species. It works to propagate genes.
Around 1600, life expectany for a human being was around 20. Around 1900, it had increased to around 40 in the western world. Today, in our parts of the world, it is 80. This is due to progress in technology, medicine, food production and sanitary conditions, all results of science. Nobody who understands anything about evolution will believe any such progress could be made through biological evolution.
And yes, contrary to what you say, fighting nature is the only way to stay alive. Nature tries to kill you constantly. The day you are in "balance with nature" is the day your body is consumed by earthworms and microbes. To argue that scientists do us a disservice by saving lives is ludicruous.
