A lot of people label random illnesses "the flu" when they are very much not the flu. Vaccinated flu infections are a lot like you describe: fever, respiratory problems, stuffy nose, etc. for 2-3 days, if the vaccine is decently effective. Unvaccinated flu infections can give you a 101+ fever for up to a week, severe body aches that make doing anything painful, in addition to a stuffy nose, post-nasal drip, sometimes even gastrointestinal symptoms. Getting the flu when you aren't vaccinated can kick your ass for like 2 weeks, easy.

I got covid around Christmas, with two vaccines and a booster shot. Kicked my ass for like 3-4 days of very mild fever, and I also had body aches and all the other flulike crap. Took until this week for my lungs to feel like they're 100% again, though -- running has felt much harder than usual lately.

I, too, wonder if the immune-compromised are basically fucked in this timeline. With folks unwilling to wear masks in public spaces, you'd have to be crazy to expose an immune-compromised person to public events any time soon.
