There’s preliminary data showing that childhood expose to Zoster provides a stronger immune response than the two shots that are currently recommended. This seems to be leading to more people getting shingles at younger ages than historically. But, it’s just preliminary data, nothing strong enough to produce CDC guidance on the issue, but something to be aware of.
Given how bad shingles is and how likely one is to have it in ones lifetime, there is an arguement to be made for natural immune reponse to Zoster rather than a vaccine immune response. Maybe we’ll see either a change in recommendation on the Varacella front or on the shingles vaccine (wihchever one it is) front at more data becomes available.
