That happens from time to time; it’s incredibly hard to predict which strains will be prevalent months down the line, and flu mutates so rapidly that what’s circulating now might be a rather different strain from what will be circulating by the time the vaccine is rolling out. It’s frequently a shot in the dark, but shooting in the dark is always going to get more hits than not shooting at all.
Another fun fact, they usually don’t just select a single strain for the yearly vaccine. They often select a handful of strains, and net on one of them being the one.
I will say that they whiffed incredibly badly on this year’s flu prediction.

So a shotgun in the dark.
