Watching the news out of Australia they are just beginning their flu season. Last year they got a seriously dangerous strain that took quite a few. As I recalled it hit 20 something’s really hard
Some flu strains are harder on the young because they haven’t been exposed to them like older adults. This was particularly true of the H1N1 strain of a few years ago. Pregnant women were especially at risk.
The point is this. Flu isn’t something to muck around with. It kills people. Getting the shot is pretty much always a better idea than not. Not a perfect idea, just a better one.
