I have chosen not to receive any Covid19 vaccinations and so I am "unvaccinated". I thought it was never going to happen, but eventually I contracted covid19, over Easter period this year. I too experienced myalgia, a mild fever. I also had a sore throat for about 2 days. I didn't completely lose my sense of smell, but coffee (for example) didn't taste great. Same with wine. That anosmia, such as it was, persisted for a week or two.
But that's it really. It was all over in about 2.5 days. I would not describe what I experienced as "harsh". I've had Influenza, and that was harsh. Sat me on my arse for a solid week. But not this. By day 4, I was doing household chores and more or less back to normal (mild anosmia not withstanding).
So, YMMV. :-)
My girlfriend got vaccinated and boosted, caught COVID, was bed ridden for several days and then general malaise and tiredness for two weeks.
I got vaccinated and boosted, went to the same party my girlfriend was infected at, stood next to the same people that infected her, took her to the hospital to get tested because we didn't think it was COVID, and I never even got infected.
Anecdotes are literally useless when discussing these things. There's so many individual variations about how you respond to COVID, to the point where your experience is likely affected by how stressed you have been the month you caught it.
This is why the people who actually care about understanding the issue collect large amounts of data, and that data largely shows getting a vaccine to significantly reduce your chance of getting it, and your chance of dying from it.
In any case, I never had any shots, got Covid last December, was sick for 3 days with a bad sore throat and recovered just fine shortly after.
Many people are rightly not so obsessed with irrational safetyism and have no problems avoiding the vaccine and getting on with life.
How could we prove this hypothesis?
and that's with 3 shots. i'm almost sure i would be in an ICU if i didn't get any shots.
