This is the most dispassionate review of whether there’s any relationship between Covid vaccination and increased tinnitus: COVID-19 Vaccine and Tinnitus: What We Know (healthline.com)3.
Relative to @drcrandon’s excellent reference to “post hoc ergo proper hoc,” (Has anyone else experienced this after a covid jab? - #23 by drcrandon), it’s estimated that 10% of the U.S. population overall suffers tinnitus to some degree (too many loud music concerts, too many loud earbuds?!) and 27% of the population age 65 or older. So what’s the likelihood in that HUGE population in the U.S. that someone just happens to have their tinnitus increase after a Covid jab for some reason and attributes it to the vaccination? And most published papers say the reported incidence of such an increase is very low. The same for myocardial injury. I didn’t bother to see where Dr. John Campbell got his 1 in 35 figure for myocardial injury caused by vaccination, but most published reports say the incidence of myocardial injury is at the level of several additional cases per 100,000 people inoculated. The risk of having myocardial injury from Covid or the common flu is far greater. Campbell has also been an ivermectin promoter so …
Everyone should have to take a good health course in high school that thoroughly discusses epidemiology and statistics.
I am not disputing that one cannot suffer tinnitus or myocardial injury if one gets a Covid booster, flu shot, RSV vaccination, etc. From what little I know, it seems unlikely, but it’s a risk vs. benefit evaluation for everyone to do on their own with their doctor’s advice. What I did mean to previously question is small group, uncontrolled, not blind studies that “several of us got …; therefore it’s a general phenomenon and everyone’s at risk…”
The placebo effect is a well-established medical fact. There’s probably an anti-placebo effect, too (if you think something bad is going to happen to you because of doing X, you’re sure to find something to blame on X…). And with the Internet, you can probably find someone else in the whole wide world who also thinks the same thing happened to them because of X. There is so much variability in the world, we need to be much more careful how we sort things out to avoid going off the rails when we shouldn’t.
