so how does one catch shingles at all?
Its complicated but to simplify it:Nearly everyone is infected with the chickenpox virus in childhood. This can occur with or without symptoms of chickenpox or an account of the chickenpox vaccine. Anyway this virus then goes to sleep in structures called nerve ganglions near the spinal cord. The body’s immunity makes sure that it does not get reactivated. When the body’s immunity weakens (because of age or other reasons) the virus can reactivate and when it does it travels down the affected nerve and reaches the skin where it causes skin blisters resulting in Shingles. Only a small portion of the body is usually affected. So to summarize the same virus caused childhood chicken pox and adult shingles.
