For one thing that 1 in 3 people is just an estimate not data. Funny though, I'm now 65 and have only ever known 1 person in my whole life who got shingles. Also you have to have had chicken pox for shingles to even be a possibility.
Also for some reason you don't want to differentiate between standard viral vector vaccines that have been around for many decades and a new experimental genetic manipulation that is still only legal on an emergency basis. Why is that???
