Last week, like millions of Americans, we received an email from Homeland Security (yikes!) explaining how we can help prevent an H1N1 flu pandemic this autumn. The more we look the more we're convinced HBOT has little if any role in this fight. Try washing your hands instead. Then cross your clean fingers for speedy delivery of an effective vaccine. Or, if you think we've missed important new evidence, post a comment, then wash your hands again.
