How effective is the chickenpox vaccine against shingles?
Research has shown 1-dose chickenpox vaccine to be 70-90% effective in preventing disease and 95% effective in preventing severe disease. Two doses of vaccine were 99% effective in preventing disease in children in clinical trials. Varicella vaccine is also very safe.
Shingles is caused by the varicella zoster virus, the same virus that causes chickenpox. You can't catch shingles from another person. However, a person who has never had chickenpox (or chickenpox vaccine) could get chickenpox from someone with shingles.
- Most people who get chickenpox vaccine will not get chickenpox. But if someone who has been vaccinated does get chickenpox, it is usually very mild. They will have fewer blisters, are less likely to have a fever, and will recover faster.
- Duration of Protection. It is not known how long a vaccinated person is protected against varicella. But, live vaccines in general provide long-lasting immunity. Several studies have shown that people vaccinated against varicella had antibodies for at least 10 to 20 years after vaccination.
- However, CDC does not have a recommendation for routine use of Zostavax in people 50 through 59 years old. Protection from this shingles vaccine lasts about 5 years, so adults vaccinated before they are 60 years old might not be protected later in life when the risk for shingles and its complications are greatest.
With the vaccine to protect against varicella zoster virus (VZV) now available, though, most kids can now avoid this infection. But anyone who has had chickenpox may later develop shingles — even children. The good news is that shingles is pretty rare in kids and teens with healthy immune systems.
- Shingles is caused by the varicella zoster virus, the same virus that causes chickenpox. You can't catch shingles from another person. However, a person who has never had chickenpox (or chickenpox vaccine) could get chickenpox from someone with shingles.
- Yes, people with shingles are contagious. However, you can not catch shingles itself from someone else. Shingles are caused by the chickenpox virus which has been dormant (staying quiet) in your body ever since you had chickenpox. So, you get shingles from your own chickenpox virus, not from someone else."
- Shingles is less contagious than chicken pox and cannot be passed from person to person. However, the varicella zoster virus can be spread from a person with shingles to someone who has never had chicken pox. The unfortunate recipient might develop chicken pox, but not shingles.
Shingles, also known as zoster or herpes zoster, is a painful skin rash caused by the same virus responsible for chicken pox: the varicella zoster virus. Even if you had chicken pox in the past, you can still contract shingles. Shingles is less contagious than chicken pox and cannot be passed from person to person.
- Chickenpox may start out seeming like a cold: You might have a runny or stuffy nose, sneezing, and a cough. But 1 to 2 days later, the rash begins, often in bunches of spots on the chest and face. From there it can spread out quickly over the entire body — sometimes the rash is even in a person's ears and mouth.
- Shingles is not usually dangerous to healthy individuals although it can cause great misery during an attack. Very rarely, shingles can lead to pneumonia, hearing problems, blindness, brain inflammation (encephalitis) or death. For about one person in five, severe pain can continue even after the rash clears up.
- Most cases of shingles last 3 to 5 weeks. Shingles follows a pattern: The first sign is often burning or tingling pain; sometimes, it includes numbness or itching on one side of the body. Somewhere between 1 and 5 days after the tingling or burning feeling on the skin, a red rash will appear.
