There's a very interesting article on vaccination and how it works (or doesn't work) at the Veterans Today website. I stumbled across it while looking for something else. It definitely caught my eye and explained a whole lot about the dangers of vaccines (and about the benefits for some) as well. The article, How Vaccinations Work by Dr. Philip Incao starts about halfway down, after many pleas for understanding and care for veterans who got Gulf War Disease back in the 1990s after the first Gulf War. Check it out--it's a damn good article.
As for us, no colds, no flu this winter. We've been eating our clove of garlic daily (as well as lots of other garlic in various dishes) and while we've had the occasional sniffles, there's been no other real cold/flu problems. If there was, we'd bring out the elderberry extract.
