Let me explain it to you and then you can ignore it and conitnue with your non-sequitors.
Microbes evolve in the same way most species - those that survive being killed off pass thier genes, the ones that provided the survival traits, to their progeny. The mutational shifts can be tracked and for influenza there is a pattern to the shifts. These can be anticipated as the CDC has been doing for many years. They induce these shifts into strains of influenza that are maintained in the CDC labs. They use these induced strains to make vaccines that are rushed in the Fall of every year to clinicians who administed them to patients at risk. It is not a perfect system but considered better than doing nothing.
Now regarding your comment about a creationist "inventing" vaccines - would it be any different to you if they were invented by an evolutionist? Would you withold them from your young children if this was the case?
Really?!? Do you have a source for this? Because my understanding is that the CDC proccess involves predicting which four or five of the known existing influenza strains are likely to be the most prevalent. And their vaccination production is tied to these existing strains with NO ANTICIPATION OF MUTATIONS.
If the CDC is actually vaccinating us against a yet to be identified strain of Influenza, I think there are many people who would like to know about that.
I am a bit ignorant, so please answer as possible:
a) When you speak of these flu microbes "mutating", are you saying they actually change DNA/# of chromosomes?
b) How did the Darwin idea help this flu process? Seems to me flu scientists are merely observing what's been happening "NOW" (i.e., within the last century) with microbes, in the interest of controlling flu. I doubt they approached the flu as "evolutionists" interested in proving evolution. And then 1 could argue if anything, their current activities are back-proving ancient evolution, which was not their intention. How did ancient fossils LEAD to doctors/pharma controlling the flu? Seems to me the cart is before the horse here, and evolution really didn't play into it; again, more that "EVOs" are using the pharma industry to prove their macro theory.
