I got to witness a 1:1 effect of covid a few weeks ago.

I got the shit and gave it to my gf. I have 0 vax, she has vax and a booster (maybe 2? Idk.) Our progression of symptoms, degree of illness etc were all identical.

I came down with it on a mon - woke up pretty sick but I had an abscess on my leg so I assumed the fever was from MRSA or some bullshit like that and so did the ER doc when I went in (abscess + fever can have you dead pretty quick so I went in)

Tues she jumped a plane to her sister's across the country, weds morning woke up with the exact same symptoms and level of general malaise that I had on Monday. Out of genuine curiosity I tracked her symptoms alongside mine it was legitimately 100% the exact same illness and progression to the day. The only difference is she was actually worse coming out of it. Had a lingering wet cough that's just now subsiding 2 weeks later. Prob also worth mentioning that she is all-around way healthier than me - eats right, works out, etc, genuinely takes care of herself a good bit better than I do.

Tldr: gf who is prob 5x healthier than me in terms of lifestyle who is double vaxd got covid the same time as me and hers was -worse-
