25Avalon you don’t get shingles from chickenpox but you can get chickenpox from shingles.
Shingles is very nasty, it can cause years of pain, it can damage your eye sight, it I can be a nightmare particularly for those with a compromised immune system.
The vaccination has no side effects.
Nobody likes vaccinations, but that is not a reason to miss one which is recommended.
My understanding is that chicken pox is an herpes virus which stays in your body, so if you had chicken pox as a child the virus is there.
Apparently shingles can occur if you are run down. That's when mine came on (see above) - I was in bed recovering from bronchitis. We had two kittens who were on the bed and so at first I thought they had fleas. However, my OH had met a friend the day before I pointed the spots out to him and he recognised it. So I went to the GP and it was shingles, caught fairly early.
Also, cold sores are an herpes virus.
