Do you have universal flu antibodies?

Did you get the swine flu in 2009? If so, you may have antibodies that will protect you from a wide variety of other flu strains for many years to come.

Paraphrasing this article:

Researchers found that individuals who survived the 2009 H1N1 virus made antibodies which were highly cross-reactive against many different influenza virus strains. What that means is that this infection induced a response that can protect these people against many different strains of influenza virus. The antibodies offer protection against H1N1 viruses in circulation over the past 10 years, as well as the deadly 1918 pandemic flu and H5N1 "bird flu." This type of immune response is rarely seen in patients after an outbreak of seasonal flu or after receiving standard flu shots.

Here's hoping that nasty flu you had awhile back was actually this variant of the swine flu.
