What is shingles?
Shingles is a painful skin rash, often with blisters. It is also called Herpes Zoster or just Zoster. A shingles rash usually appears on one side of the face or body and lasts from 2 to 4 weeks. Its main symptom is pain, which can be quite severe. Other symptoms of shingles can include fever, headache, chills, and upset stomach. Very rarely, a shingles infection 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. This is called post-herpetic neuralgia.
Shingles is caused by the Varicella Zoster virus, the same virus that causes chickenpox. Only someone who has had chickenpox, or rarely, has gotten chickenpox vaccine, can get shingles. The virus stays in your body, and can cause shingles many years later.
You can't catch shingles from another person with shingles. However, a person who has never had chickenpox (or chickenpox vaccine) could get chickenpox from someone with shingles. This is not very common.
Shingles is far more common in people 50 and older than in younger people. It is also more common in people whose immune systems are weakened because of a disease such as cancer, or drugs such as steroids or chemotherapy. At least 1 million people a year in the United States get shingles.
A vaccine for shingles was licensed in 2006. In clinical trials, the vaccine reduced the risk of shingles by 50%. It can also reduce pain in people who still get shingles after being vaccinated.
A single dose of shingles vaccine is indicated for adults 60 years of age and older.
Which people should not get shingles vaccine or should wait?
A person should not get shingles vaccine who:
- has ever had a life-threatening allergic reaction to gelatin, the antibiotic neomycin, or any other component of shingles vaccine. Tell your doctor if you have any severe allergies.
- has a weakened immune system because of AIDS or another disease that affects the immune system; treatment with drugs that affect the immune system, such as prolonged use of high-dose steroids; cancer treatment such as radiation or chemotherapy; cancer affecting the bone marrow or lymphatic system, such as leukemia or lymphoma.
- is pregnant, or might be pregnant. Women should not become pregnant until at least 4 weeks after getting shingles vaccine.
Someone with a minor illness, such as a cold, may be vaccinated. But anyone with a moderate or severe illness should usually wait until they recover before getting the vaccine. This includes anyone with a temperature of 101.3 °F (38.5 °C) or higher.
What are the risks from shingles vaccine?
A vaccine, like any medicine, could possibly cause serious problems, such as severe allergic reactions. However, the risk of a vaccine causing serious harm, or death, is extremely small. No serious problems have been identified with shingles vaccine.
- Redness, soreness, swelling, or itching at the site of the injection (about one person in three).
- Headache (about one person in 70).
Like all vaccines, shingles vaccine is being closely monitored for unusual or severe problems.
What if there is a moderate or severe reaction?
What should I look for?
- Any unusual condition, such as a severe allergic reaction or a high fever. If a severe allergic reaction occurred, it would be within a few minutes to an hour after the shot. Signs of a serious allergic reaction can include difficulty breathing, hoarseness or wheezing, swelling of the throat, hives, paleness, weakness, a fast heart beat, or dizziness.
What should I do?
- Call a doctor, or get the person to a doctor right away.
- Tell your doctor what happened, the date and time it happened, and when the vaccination was given.
- Ask your provider to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS) form. Or you can file this report through the VAERS website at Web Site, or by calling 1-800-822-7967.VAERS does not provide medical advice.
How can I learn more?
- Ask your doctor or other health care provider. They can give you the vaccine package insert or suggest other sources of information.
- Contact the Centers for Disease Control and Prevention (CDC): call 1-800-232-4636 (1-800-CDC-INFO) or visit the CDC's website at Web Site.
