I saw another TV ad for Shingrix. Looks like they lowered the claimed effectiveness to 90%.Win and Annie, I had the new shingles vaccine in mind when I wrote that. Are you aware that there is a new one? It came out this year, and requires two shots a few months apart, and is supposed to be vastly superior to the original one. I've had both shots; nothing to it, no side effects at all.
Shingrix is 97% effective at preventing herpes zoster (shingles) in folks over 50 whereas the (older) Zostavax shot is 50-64% effective in preventing shingles in those 50-70 and even lower for those over 70. Shingrix also stays effective for longer.
And once again, that's how science works. When something better comes along, we use it. Why not?
Well, when they're selling something, we know they'd NEVER exaggerate. That just wouldn't be right............
