The new study would explain why so many people over the age of 60 -- whose bodies were likely exposed to similar flu viruses over the decades -- have been found to carry antibodies or other kinds of immunity against H1N1. In fact, the CDC now admits pre-existing antibodies against the virus are found in about one third of H1N1 2009 patients over the age of 60, a fact that shows some natural immunity to the new H1N1 virus exists in many people.
