Not gonna lie: this vaccine made me sick as a dog for a couple of days. I would still get it again in a heartbeat. A couple of days under the weather vs a debilitating condition that can cause months of agony is a no-brainer. Longevity is a nice bonus, but it’s just that, a bonus. Ask any family practice or gerontologist if shingles is a big deal. They’ll confirm that yes, you really, really want to avoid it.
Many years ago, I had shingles and it was a great torture for a few months, until the pain faded away. It was almost impossible to sleep, which made everything worse than just because of the pain.
The antiviral treatment that I had started promptly had a very obvious effect, but even with that a very long time passed until the pain gradually decreased so much as to be no longer felt.
