How come people with chicken pox can get shingles but normal people can't, and does that mean it could be bad to get vaccines?

No the opposite: if you are immune ( due to the vaccine) and do not get chicken pox you can not have shingles as shingles is the reactivation of the dormant chicken pox virus from the nerve root.

Latent: When you get chicken pox as a child, the virus lies dormant in nerve roots forever. When your immune system weakens or with age it can reemerge and does so along the nerve root where it has been "sleeping". There is now a vaccine against chicken pox and a shingles vaccine. I recommend you consider the vaccine if you have no contraindication. Ask your doctor. .

Go Meet A Cool Freak: Shingles is Chicken Pox coming back to haunt you later in life.That doesn't make you abnormal.Almost everyone has had chicken pox as kids.It's just us'lucky'few who then get the shingles.And there's vaccines for both,so chill-out,dude!Not that vaccines are wonder drugs,but they help.you know,so many people get chicken pox that you could say THAT is the norm and that those that don't are the freaks

So shingles is: actually a reinfection of chickenpox. Which means if you didn't contract the chicken pox virus, then you won't have the virus in your body to attack and lead to shingles. If you have never had the chicken pox virus you can get the vaccine to prevent it. If you had the ckicken pox, then you can get the shingles vaccine which reduces (not eliminates) your risk of getting shingles. Hope that helps

Vaccines prevent: Chicken pox is caused by a varicella zoster virus. Once you've had it, it never fully clears from your system and therefore, you are susceptible to having reactivation as manifested by shingles. The chicken pox vaccine prevents chicken pox and therefore future risk of shingles.

Varicella: Either with the vaccine or natural varicella (chicken pox), there is a risk of shingles activation within your own body. However, both vaccine and natural disease prevent you from "catching" chickenpox or shingles.

Ch pox virus causes: Shingles. Evidently the virus can hang around for years and strike again when immunity is compromised, as in older people. Vaccination boosts the immune mechanisms against the virus.
