Anecdata: I've had Covid once. Whole family got it. Going out for walks was not impossible but winded me badly. We all recovered in about a week. I had a single dose of Pfizer from about 3 months before. I never got a second dose. Kids all breezed through it. The first month afterward required a lot of pushing and experimenting to get my body to respond to working out. Stuff like walking for extended periods of time was easy, but anything that got my HR into Zone 3 and above was taxing. After that month, things got progressively easier. I also made a lot of other changes: diet improved tremendously, I lost 30+ pounds, and I feel like a completely different person now than before. The only other people I know personally who got long covid had gotten 2 doses but had other issues like being overweight or having a horrible diet.
