Chickenpox can happen more than once once (I've seen it happen), but usually it only comes once in a lifetime.
Unfortunately, later in life you can suffer shingles, because chickenpox is caused by a virus which never leaves the body and settles, lying dormant for years, in nerve roots. When your immune system is depressed or weakened, the virus can be reactivated as a shingles infection.
Getting chickenpox twice is unusual, but not impossible. See your health care provider to check your diagnosis. Ask for a culture or smear of the lesions or a titer test to demonstrate increasing IgM titers. Another explanation is more likely.
It doesn't usually happen because either vaccination or one case of the viral disease (varicella zoster) usually results in immunity. But it can recur if the body does not react completely. It is more dangerous if it recurs in an adult, because it manifests as shingles (called herpes zoster), which is a more serious condition.
Normally when you get chicken pox, your body forms cells to "remember" the virus's proteins. The virus is killed off, so you will not be able to get it again. But you can still get shingles, because some of the virus remains dormant in nerve cells in the body.
You cannot get the chicken pox twice. The second outbreak is shingles.
If you have chickenpox, you can spread it to other people, even if you had it before.
It's possible, but not likely, to get chickenpox twice after getting chickenpox vaccine. Talk with your health care provider to find out how certain was the diagnosis.
A carrier of chickenpox is someone who is infected but doesn't have symptoms. Most people who get chickenpox do not get infected twice. You are not likely to get chickenpox as an adult if you had them as a child.
You cannot get chickenpox twice. Your body adapts to the virus and you no longer break out. You can, however, get shingles later in life from the chickenpox virus still in your body.
There are no special risks or side effects from extra chickenpox vaccine.
There is no chickenpox RNA; chickenpox is a DNA virus.
A person with a history of chickenpox or history of chickenpox vaccine will typically have a positive antibody test for chickenpox.
Chickenpox vaccine is useful. It reduces the risk of chickenpox, of complications, hospitalizations, and deaths from chickenpox, and of shingles.
Chickenpox is not an autoimmune disease. Chickenpox is a viral communicable disease.
