A key ingredient for a universal flu vaccine may come from llamas
What I don't get is why are we are spending resources on artificially fortifying our bodies for something that's not event a serious threat? We as society already possess capabilities to survive against threats even more serious. Our body is magnificently apt at defending itself. Disease becomes a problem for us only when we are not taking good care of ourself and our environment, like all the disease outbreaks in UK and US in 1800-1900 when we were living in filthy environment of cities and consuming food/water contaminated by our own filth. Thanks to sanitization revolutions we were able to regain our health. We can once again reach pinnacle of our health if we get rid of newly create pollution in our environment/food.
