Medical knowledge evolves constantly. Medicine is never a "settled science," and it never will be. (George Washington's death was agonizing because his doctors followed the "settled science" that recommended leeches for ameliorating a serious chill.) The best we can do is to allow a free market in medical research and patient outreach, then let the individual decide what is best. After all, this is nothing more than freedom based upon self-ownership. This conclusion would be the same if those at the CDC were not corrupt but honest citizens attempting to honor their mandate. However, we know that power corrupts, and we saw this demonstrated to our horror with sanctions against respected researchers and doctors who disagreed with the CDC's recommended approach. We are now learning that these respected researchers and doctors were correct and that the CDC's recommendations, which became diktats, were harmful.
