What you should know about the Shingles Vaccine (Shingrix)
Shingles vaccination is the only way to protect against shingles and postherpetic neuralgia (PHN), the most common complication from shingles.
CDC recommends that healthy adults 50 years and older get two doses of the shingles vaccine called Shingrix (recombinant zoster vaccine), separated by 2 to 6 months, to prevent shingles and the complications from the disease. Your doctor or pharmacist can give you Shingrix as a shot in your upper arm.
Shingrix provides strong protection against shingles and PHN. Two doses of Shingrix is more than 90% effective at preventing shingles and PHN. Protection stays above 85% for at least the first four years after you get vaccinated. Shingrix is the preferred vaccine, over Zostavax®(https://www.cdc.gov/vaccines/vpd/shingles/public/zostavax/index.html) (zoster vaccine live), a shingles vaccine in use since 2006. Zostavax may still be used to prevent shingles in healthy adults 60 years and older. For example, you could use Zostavax if a person is allergic to Shingrix, prefers Zostavax, or requests immediate vaccination and Shingrix is unavailable.
Who Should Get Shingrix?
Healthy adults 50 years and older should get two doses of Shingrix, separated by 2 to 6 months. You should get Shingrix even if in the past you:
- had shingles
- received Zostavax
- are not sure if you had chickenpox
Shingrix reduces the risk of shingles and PHN by more than 90% in people 50 and older. CDC recommends the vaccine for healthy adults 50 and older.If you had shingles in the past, you can get Shingrix to help prevent future occurrences of the disease. There is no specific length of time that you need to wait after having shingles before you can receive Shingrix, but generally you should make sure the shingles rash has gone away before getting vaccinated.
You can get Shingrix whether or not you remember having had chickenpox in the past. Studies show that more than 99% of Americans 40 years and older have had chickenpox, even if they don’t remember having the disease. Chickenpox and shingles are related because they are caused by the same virus (varicella zoster virus). After a person recovers from chickenpox, the virus stays dormant (inactive) in the body. It can reactivate years later and cause shingles.
What are the possible side effects of Shingrix?
Studies show that Shingrix is safe. The vaccine helps your body create a strong defense against shingles. As a result, you are likely to have temporary side effects from getting the shots. The side effects may affect your ability to do normal daily activities for 2 to 3 days.
Most people got a sore arm with mild or moderate pain after getting Shingrix, and some also had redness and swelling where they got the shot. Some people felt tired, had muscle pain, a headache, shivering, fever, stomach pain, or nausea. About 1 out of 6 people who got Shingrix experienced side effects that prevented them from doing regular activities. Symptoms went away on their own in about 2 to 3 days. Side effects were more common in younger people.
You might have a reaction to the first or second dose of Shingrix, or both doses. If you experience side effects, you may choose to take over-the-counter pain medicine such as ibuprofen or acetaminophen.
Severe allergic reactions to any vaccine are very rare. Signs of a severe allergic reaction can include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, and weakness. These would start a few minutes to a few hours after the vaccination. If you have a severe allergic reaction or other emergency that can’t wait, call 9-1-1 or go to the nearest hospital. Otherwise, call your doctor.
If you experience side effects from Shingrix, you should report them to the Vaccine Adverse Event Reporting System (VAERS). Your doctor might file this report, or you can do it yourself through the VAERS website, or by calling 1-800-822-7967.
If you have any questions about side effects from Shingrix, talk with your doctor.
The shingles vaccine does not contain thimerosal (a preservative containing mercury).
