The human influenza virus H1N1 that caused the 2009 flu pandemic, and H9N2, an avian influenza virus that is endemic in bird populations in Asia, are close cousins — close enough that they can swap genes if they find themselves in the same cell, resulting in new viruses that are a patchwork of the parent strains.

In the case of flu, most people had antibodies to seasonally circulating influenza strains, but these antibodies were a poor match to the pandemic virus.

Influenza pandemics occur when a totally new strain of the virus emerges, against which nobody's immune system is fully prepared; that's why both the healthy and the weak are vulnerable.
