The dosage of Shingrix your doctor prescribes may vary based on certain factors. Talk with your doctor about the dosage you should receive.

Receiving Shingrix

The Shingrix vaccine is given as an injection into your muscle. It’s given in two separate doses.

It’s very important that you receive both doses of Shingrix. Your doctor will explain how Shingrix will be given to you and where you’ll receive it. They’ll also explain your Shingrix dosing schedule, including when you should receive your second dose.

Most adults receive their second Shingrix dose 2 to 6 months after receiving the first dose. But if you have a weakened immune system, your doctor or pharmacist may suggest getting your second dose 1 or 2 months after getting the first Shingrix dose.

Talk with your doctor or pharmacist if you have questions about Shingrix dosing.

Below you’ll find answers to a few commonly asked questions about Shingrix.

Will I experience certain side effects after the second dose of Shingrix?

No. Side effects after either the first or second dose of Shingrix are expected to be the same.

In the drug’s studies, people were more likely to report headache and shivering after receiving the second Shingrix dose compared with the first dose. But these side effects can happen after either dose of Shingrix.

Talk with your doctor or pharmacist if you have more questions about Shingrix’s side effects.

How does Shingrix compare with Zostavax?

Shingrix and Zostavax are both vaccines used to help prevent varicella-zoster, the virus that causes shingles.

But Zostavax is no longer available in the United States. This is because Shingrix was found to be more effective at helping prevent shingles than Zostavax.

If you have questions about how Shingrix compares with Zostavax, talk with your doctor or pharmacist.

Is Shingrix a live vaccine?

No, Shingrix is not a live vaccine. Live vaccines contain a live, weakened version of the germ they protect against. While rare, it’s possible for live vaccines to cause infection. When this happens, the infection is usually much milder compared with infection caused by the virus the vaccine protects against.

Shingrix is an inactivated vaccine. This means it contains a version of the varicella-zoster virus that’s no longer alive. Inactivated vaccines cannot cause infection with the virus they protect against.

Another shingles vaccine, Zostavax, is a live vaccine. But Zostavax is no longer available in the U.S.

Your doctor or pharmacist can answer questions you may have about differences between live and inactivated vaccines.

Can I receive other vaccines at the same time as Shingrix?

Yes, it’s generally considered safe to receive other vaccines at the same time as Shingrix.

If you receive other vaccines at the same time as Shingrix, your doctor or another healthcare professional will inject the vaccines into different sites. This may include injecting them into different arms.

Talk with your doctor or pharmacist if you have questions about other vaccines. They can provide more information on the best time for you to receive them.

What are the age recommendations for Shingrix? Can someone under 50 years of age receive the vaccine?

Yes, it’s possible for someone under the age of 50 years old to receive the Shingrix vaccine.

Shingrix is prescribed to help prevent shingles in adults ages:

• 50 years or older
• 18 years or older who have a higher risk of shingles due to a weakened immune system

For example, if you’re under the age of 50 years old and have had a solid organ transplant, you are more likely to have a weakened immune system. This may be due to the treatments your doctor prescribes to help prevent your immune system from rejecting the transplant. In this case, your doctor may have you take Shingrix to help prevent a shingles infection.

Talk with your doctor or pharmacist to learn more about age recommendations for vaccines, including Shingrix.

How does Shingrix work? And how long does it take to start working?

Shingrix’s mechanism of action (how it works) is by teaching your body’s immune system to recognize and attack the varicella-zoster virus. This is the virus that causes shingles. (Varicella also causes chickenpox, but Shingrix does not protect against chickenpox.)

Shingrix is an inactivated vaccine, which means it contains a version of the varicella-zoster virus that’s no longer alive. The vaccine works by presenting this version of the virus to your immune system. Your immune system learns to recognize and create antibodies against the varicella-zoster virus. These antibodies stay in your body. So if your immune system detects the varicella-zoster virus in your body, it activates these antibodies to attack the virus. This helps prevent infection.

Shingrix starts working after the first dose. But it takes two doses and some time for your body to adapt and protect itself from shingles completely. The vaccine is considered fully effective about 1 month after the second dose.

Talk with your doctor or pharmacist if you have questions about what to expect with Shingrix.

It’s not known whether Shingrix should be given during pregnancy. If you’re planning a pregnancy or can become pregnant, talk with your doctor before taking this vaccine.

Shingrix and breastfeeding

In general, Shingrix is considered safe to receive while breastfeeding. That said, ask your doctor about whether they feel it’s safe for you specifically.

The Food and Drug Administration (FDA) approves prescription drugs such as Shingrix for certain conditions. Approved uses for Shingrix are described below.

Use to help prevent shingles

Doctors may prescribe Shingrix to help prevent shingles (also known as herpes zoster). It’s used for this purpose in adults.

Specifically, Shingrix is prescribed to help prevent shingles in adults ages:

• 50 years or older
• 18 years or older who are at a higher risk of shingles due to a weakened immune system

Shingles is an infection that causes a painful, burning skin rash. Depending on your skin tone, this rash may appear red, dark brown, dark pink, or purple.

Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. If you’ve had chickenpox in the past, the varicella-zoster virus may stay inactive in your body for a long time before coming back as shingles.

Note: Shingrix does not help prevent chickenpox, and doctors will not prescribe it for this purpose.

This article describes Shingrix’s uses and dosage, ways to save on cost, and more. Let your doctor know if you have questions about Shingrix or would like more details about it.

Here’s a list of some possible questions you may want to ask your doctor:

• Does Shingrix contain neomycin?
• When should I receive my second dose of Shingrix?
