Here is the excerpt of Dr. Poland's answer re tinnitus.
"So, this is a very interesting question that you asked me. About an hour after my second dose, I developed severe ringing in my ears. About 10 weeks later, it's starting to decrease. This is called tinnitus. It's a very common phenomena. I've queried the CDC about it. Some 1000 reports have been received in regards to this. So, like any side effect, if you feel you've had a side effect from a vaccine, we ask people please report it, you can go online, and just type in VAERS. And it's an online reporting system that you can report, it's the only way that we can find out about rare safety signals.

So, so far, the number of people who have developed ringing in their ears has not exceeded the expected baseline if there were no COVID vaccines being given. So, what you want to know is by giving a vaccine, are you seeing a higher rate than among people who have not gotten the vaccine, and it has thus far not reached that state, but something to be aware of. By way of encouragement, and I've talked to a number of ENTs about this, they believe that if that's real, it's on a transient or temporary inflammatory basis, and that most all of those will resolve in the six-to-12-month time period. We'll see if that's true. But that seems to be the trend."

In other words, the number of currently reported cases of tinnitus following vaccination for COVID does not exceed the number of tinnitus cases that are generally reported when vaccination is not happening. Experts are not discounting the possibility of tinnitus as a side effect and believe it may be a temporary inflammation response.
