I understand that you had a bad experience and understand why you wouldn't take more. I agree with you, that you made the right decision.That doesn't apply if the first shot made your pre-existing tinnitus worse (which happened to me). After my experience with my first Pfizer shot, there's absolutely no way I'm getting a second. In the UK at the moment AstraZeneca has been phased out and the only available vaccine options are Pfizer or Moderna which are both mRNA and I now know for an absolute fact that my tinnitus reacts adversely to mRNA vaccines.
I don't think that means that you can apply your personal experience with everyone else and tell everyone else not to get it. If that was the case, we should never take any drugs because someone somewhere at one time had an adverse side effect.
