H1N1 silver lining

A new study in the Journal of Experimental Medicine (BBC article link) shows that winners of the 2009 H1N1 Flu Award (*cough*choke*cough*) may now have enhanced resistance to a wide range of flu viruses.  So maybe there is a silver lining to my household's Sept. 2009 bout with that strain.
But I'm still keeping some guaifenesin tablets in the cupboard.
