Totally believable.
I had the Moderna.
I suspect that I’d had the “beta Version” of COVID/CCP in January of 2020, several days of almost constant chills, shortness of breath/cough. The SOB lasted for nearly a month...couldn’t say the first line of the pledge of allegience without at least one catch up breath.
Had several episodes from February - October when I’d have a couple days of respiratory symptoms, felt like “circling the drain” but never anything full blown. Then had some definite exposure in late November, again, some “circling the drain” in early December.
My wife had the “beta” in January 2020 as well. Also the exposure in late November but she did go into full blown COVID, ended up being hospitalized for eight days over Christmas, sent home with oxygen (now almost fully recovered!). So I was definitely exposed to her. But I tested negative.
So…
Moderna I on January 15
<8 hours - felt great, “felt like Superman”—did weight training, walked 2/3 mile. Everything great.
9 - 33 hours - “worst hangover of my life” headaches, chills, nausea—even the thought of food was revolting.
34 - 40 hours - “is this menopause?” Hot flashes!
After that, pretty much back to normal except that about 10 days after I began getting weird joint pains, a bout of gout plus aches where I’d never had them before. Lasted about 5- days.
Moderna II on February 12
This time around with Tylenol before and steadily for 30 hours afterward: a few chills, no nausea, headaches that would come and go in less than 30 seconds and an incredible appetite. Hungry as a horse.
