@arstechnica Having gotten shingles at 18 and having both Mom and Grandma have nasty bouts with it themselves - get Shingrix! The achy side effects are way better than the weeks and months of shingles pain.

Also Grandma got Shingles twice - proving her doctor wrong, that she didn't need Zostavax because she already had had shingles. Grandma is all vaxxed up now. Too late on the dementia front though.
