I think what the nurse meant is that it is currently unknown how long the chickenpox vaccine is effective...

Don't think so, but that ain't the weird part. As I explained in my reply #66, she said:

1. If you never get chickenpox or the vaccine, you will never get shingles.

2. If you never get chickenpox, but get the vaccine, you may get shingles.

3. The same vaccine that may give you shingles in a higher dose later in life may keep you from getting shingles.

I ain't no doctor so I don't know if any of this is right but I find the whole matter convoluted and borderline ridiculous.

Note: This all refers to Zostavax, it happened long before Shingrix was introduced.

You are correct.

Thanks for clearing that up.

The old vaccine - Zostavaz - which was given before late 2017 - actually has live, but weakened, virus in it.

So, after a Zostavax shot, some of those weakened viruses probably take up life long residence in your nerve cells, and they have the potential to become shingles later in life.

I presume the long term goal is to wipe out chickenpox everywhere, just like smallpox has been almost completely wiped out. When you wipe out chickenpox, you wipe out shingles, too.

The new vaccine - Shingrix - does not appear to have live virus, but I may be mistaken.
