All I know is that because I was traveling so much internationally, I took three "vaccines" (still got COVID). I didn't take anymore because the last one I took (not the first two) gave me a headache that didn't go away for FOUR DAYS. Y'all. I can't be sick for FOUR DAYS. Ain't nobody got time fo dat. Anyway, I got COVID anyway, and was prescribed something or other, can't recall the name but it was the same medication Biden took. I felt OK till I started taking the meds, which I took for one day. The side effects were exactly the same as COVID so it was hard to tell the difference but as soon as the meds were out of my system (I'm figuring a few hours, maybe up to 12 hours), I felt much better, and by the third day I was fever free and felt fine. I had a lingering cough for a few more days and then that was it. Believe me, I've felt a lot worse in my life than when I had COVID but my point was that I still got it. Didn't take the meds as prescribed at all. Oh, and the doctor told me that Biden took it and had a relapse a few days later so expect that but since I stopped taking the meds after one day, I didn't relapse either.
