I challenge the statement in the article that once you develop antibodies to a virus you can’t get it again and worse they use chicken pox as one of the examples. The varicella zoster virus is the cause of chicken pox and I suffer chronic nerve damage to this day on my face as proof that the pox never leaves your body and your antibodies are incapable of preventing its return. They just call it shingles on subsequent appearances and in my case it was many times worse than the chicken pox. I believe it is also infectious in the shingle stage through shedding from the open pox. When shingles presented on me, I had the familiar chicken pox blisters on my right check under my eye with excruciating pain like a blowtorch that lasted for days and the doctor was concerned about it getting into my right eye. After having chicken pox, I have heard that there are no guarantees one will not get shingles even after receiving the two shot vaccine protocol. The bottom line is that viruses are nasty entities, hovering somewhere between being alive and dormant seeds possessing the potential for life.
I stopped reading after Your first sentence. He did not say that. He said if you catch it again your system defenses will probably adapt faster and it will be less severe
So let me help educate you and reduce you promulgating bad information. Varicella Zoster is NOT a reinfection as you state, the fact is that Varicella takes up a position in the Dorsal Root Ganglion (DRG) of the spinal column where sensory neurons live. This is a region of the body that is considered immunosequestered which means that the immune system does not cross into this region. When a patient gets Shingles, it is because of a immunosuppressed state that causes the rash to activate down a nerve root dermatome. This is exactly why Shingles can be traced to a region of the body and never crosses the midline (except in the rarest case of disseminated shingles when the immune system is completely obliterated)
Thus, while you do shed active varicella and primary chicken pox CAN be transmitted from the shingles, the shingles IS NOT a reinfection of the same virus, it is a loss of surveillance in the body which causes the process.
