There's usually only one pandemic of flu per year, though I don't believe that there's a rule about it. However just because it killed thousands doesn't mean much when the population is as large as it is. I would guess that most people who caught it (assuming it was a pandemic) were mildly sick for a few days, some people had a bit worse case, and one in a million died of it and was counted.
FWIW, I don't really remember the 2009 swine flu, and that's only 5 years ago, so it can't have been very noticable...in the US. My wife's mother was already frail and around 90, and she's still around, so it can't have been all that devastating.
OTOH, this doesn't mean that when crossed with another strain it wouldn't be highly contagious bad news. If it was a pandemic, then it is good at spreading among humans, even if it's usually so mild that they don't notice it.
