We won't talk about influenza for another couple of weeks but there were some news reports this weekend based around a paper to be published in Nature this week that shows that survivors of the 1918 flu pandemic are still producing antibodies to the virus 90 years later. It is not known how unusual this is or whether this is typical of immunity to influenza strains.
