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.
Their vaccination porduction is tied to existing strains because that is what they can produce. Public health officials anticipate mutation and worry that vaccines for last years strains will be ineffective against what appears this year. They do the best they can. Unfortunately anticipating that something will mutate is different than being able to develop a vaccine to protect against what the virus will mutate into.
Medicine is for those without faith. True believers find all they need in faith.
