Side Effects of Shingrix: What You Need to Know

Shingrix (recombinant varicella zoster virus) is a prescription vaccine used to help prevent herpes zoster, which is also called shingles. Shingrix can cause side effects that range from mild to serious. Examples include pain at the vaccine site and muscle pain.

Shingrix is used to prevent shingles in adults who are:

  • ages 50 years and older
  • ages 18 years and older with a higher risk of shingles due to having a medical condition or taking medication that suppresses the immune system

The active ingredient* in Shingrix is recombinant varicella zoster virus, which is a biologic medication.

Shingrix comes as a liquid suspension that a healthcare professional will give you as an injection into a muscle. It’s usually injected in the upper, outer side of an arm.

Side effects won’t happen to everyone, but some people may experience mild to serious side effects during their Shingrix treatment. Examples of this vaccine’s commonly reported side effects include:

In studies, the artificial intelligence (AI) technology used in some online health services for preliminary screening before connecting patients with a doctor actually outperformed real physicians in terms of reaching an accurate diagnosis, CNN AI technology correctly diagnosed conditions in 81% of patients, compared to a 72% average for accurate diagnoses among real physicians over a five-year period.

For example, in Shingrix studies , the following side effects were reported more frequently following the second dose than the first:

People may have different experiences with the first and second doses of Shingrix. If you’re concerned about side effects with the second dose, talk with your doctor.

How soon do side effects start after receiving the Shingrix vaccine?

Side effects can start as soon as you receive your dose. While they won’t happen to everyone, pain, discoloration, and swelling at the injection site can appear right away. But these are short-term side effects that usually last 2 or 3 days.

Some side effects may occur later. In Shingrix studies , the following side effects were reported up to 30 days after the dose:

  • chills
  • injection site itchiness
  • malaise (a general feeling of discomfort)
  • joint pain
  • nausea
  • dizziness

If you’re concerned about how soon side effects can start with Shingrix, talk with your doctor. They can help you prepare for immediate side effects and manage any that happen later.

Can side effects of Shingrix last longer than a week?

Yes, some side effects of Shingrix can last longer than a week, but most usually last about 2 to 3 days. If you’re concerned about side effects lasting longer than a week, talk with your doctor.

Learn more about some of the side effects Shingrix may cause.

Guillain-Barré Syndrome

Guillain-Barré syndrome (GBS) is a very rare side effect of some vaccinations including Shingrix. With GBS, your immune system attacks your peripheral nervous system. (These are nerves that branch out of the brain and spinal cord.)

In Shingrix studies , people have developed GBS up to 42 days after receiving the vaccine. Symptoms of GBS include mild weakness to severe paralysis that affects your ability to breathe on your own.

Doctors cannot predict who will have GBS after a vaccine. Having had GBS in the past doesn’t necessarily mean you’ll have it again with the Shingrix vaccine. And if you have GBS with your first dose of Shingrix, you can still receive your second dose.

What might help

If you experience weakness after receiving Shingrix, talk with your doctor. Most people recover from GBS, even severe forms of the disease. Still, GBS can become life threatening. If you’ve had GBS in the past, tell your doctor. They may still recommend the vaccine but can discuss any concerns you may have.

Muscle pain

People may have muscle pain where they receive their vaccine. This is a local side effect. But another common side effect is myalgia, which is general muscle pain. In Shingrix studies , this side effect was usually mild.

What might help

If you’re concerned about muscle pain and how long it will last after receiving Shingrix, talk with your doctor. They may recommend an over-the-counter pain reliever such as Advil (ibuprofen) or Tylenol (acetaminophen). Their recommendation for which pain reliever is best for you depends on your other medical conditions and any other medications you’re taking.

Having muscle pain from your first dose doesn’t predict whether you’ll have muscle pain after your second dose. Before receiving your second dose, ask your doctor what you can do to prevent muscle pain. For example, they may recommend taking a pain reliever before you receive the vaccine to help manage myalgia.

Fainting

Some people faint when they receive a vaccination, including the Shingrix vaccine. Right before fainting, some people experience trouble seeing, seizure-like movements of the arms or legs, and burning or stinging of the skin.

What might help

Tell your doctor if you have a history of fainting after receiving a vaccination. Your doctor will tell you whether the benefits of the vaccine outweigh the possible side effects. If you still need to receive Shingrix, your doctor will make sure procedures are in place to prevent an injury from fainting.

Allergic reaction

Like most drugs, Shingrix can cause an allergic reaction in some people. Symptoms can be mild to serious and can include:

  • skin rash
  • itchiness
  • flushing (temporary warmth, redness, or deepening of skin color)
  • swelling under your skin, usually in your eyelids, lips, hands, or feet
  • swelling of your mouth, tongue, or throat, which can make it hard to breathe

What might help

If you have mild symptoms of an allergic reaction, such as a mild rash, call your doctor right away. They may suggest a treatment to manage your symptoms. Examples include:

  • an antihistamine you swallow, such as Benadryl (diphenhydramine)
  • a product you apply to your skin, such as hydrocortisone cream

If your doctor confirms you’ve had a mild allergic reaction to Shingrix, they’ll decide whether you should receive your second dose.

If you have symptoms of a severe allergic reaction, such as swelling or trouble breathing, call 911 or your local emergency number right away. These symptoms could be life threatening and require immediate medical care.

If your doctor confirms you’ve had a serious allergic reaction to Shingrix, you may need to skip your second dose.

  • which dose you received (the first or second injection)
  • how soon you had the side effect after receiving the injection
  • what your symptoms were
  • how your symptoms affected your daily activities
  • what other medications you were taking
  • any other information you feel is important

Shingrix may not be right for you if you have certain medical conditions. This is known as a drug-condition interaction. Other factors may also affect whether this vaccine is a good option for you. Talk with your doctor about your health history before each Shingrix injection. Factors to consider include those described below.

History of reaction to vaccines. If you’ve had a reaction to a vaccine in the past, such as fainting, tell your doctor before receiving the Shingrix vaccine. They’ll tell you whether Shingrix is safe for you. If you’ve fainted before with a vaccine, your doctor will make sure you’re in a safe environment when you receive Shingrix.

Allergic reaction. If you’ve had an allergic reaction to Shingrix or any of its ingredients, your doctor will likely not prescribe it for you.

Alcohol and Shingrix

Some drugs interfere with alcohol, but the Shingrix vaccine isn’t one of them. If you drink alcohol, ask your doctor whether it’s safe to drink any before or after receiving a dose of Shingrix.

Pregnancy and breastfeeding while taking Shingrix

It isn’t clear whether Shingrix is safe during pregnancy because there isn’t enough information. Tell your doctor if you’re pregnant or planning to become pregnant when you receive your Shingrix vaccines.

It’s also not known whether Shingrix passes through breast milk. Tell your doctor if you’re breastfeeding or will be breastfeeding when you receive your Shingrix vaccines. They can help you determine whether the benefits of breastfeeding your child outweigh the possible risks.

Local side effects with Shingrix are common but temporary. Long-term and serious side effects are rare. If you have questions about side effects that Shingrix can cause, talk with your doctor. Examples of questions to help get you started include:

  • How do the side effects of the first dose of Shingrix compare with those of the second dose?
  • Will side effects of Shingrix be worse if I’ve already had shingles?
  • Is chicken pox a side effect of Shingrix?
