That's my view. To my surprise, I just had shingles. I had the new Shingrix vaccine about 4-5 years ago, which was an ordeal (at least for the first shot; the second one was not so bad). My doctor reminded me that even the new Shingrix vaccine is only about 50% effective.
My bout started in my left ear for a few days and then progressed to my left temple. Thankfully all I experienced was pain, sometimes bordering on excruciating, but I had no effects on my hearing. I'm still thankful for the vaccine and believe it protected me from permanent harm. I can deal with some pain but losing eyesight or hearing would be really catastrophic.
