Pre-existing immunity to swine flu

Not surprisingly, it looks like we're doing much better than the sensationalist fear-mongering might have led us to believe. This paper recently published in the Proceedings of the National Academy of Sciences (USA) explains how viral immunologists thought that due to antibodies primed by previous influenza strains "the severity of an S-OIV [swine H1N1] infection...would not differ much from that of seasonal flu." They go on to state "These results are consistent with reports about disease incidence, severity, and mortality rates associated with human S-OIV." Just add swine flu to the other reasons to keep your Vitamin D levels up (easy to check with a simple blood test), hands washed, sleep and food balanced, etc. See the earlier post on additional prevention.
