Just anecdotally, my family and some friends both got pretty bad flus this January. I mean, not sure it was flu, wasn’t covid, but mild to moderate respiratory symptoms with lots of fatigue, coughing and sneezing for like 2 and a half weeks. No fever.
In Europe, they're currently even available for under a euro (or under two euros for a 'regular' expiry date and RSV as well) if you buy them online instead of at retail. For example [1] or [2] (I have no affiliation with the shop).
I also got this, felt like a cold that just took forever to clear. Wasn't covid, but didn't feel as bad as proper flu. I got my flu shot going into the season late last year.
