Shingles, also known as herpes zoster, is a painful rash caused by the same virus that causes chickenpox. According to the Centers for Disease Control and Prevention (CDC), about 1 in 3 people in the United States will develop shingles at some point in their lifetime.

While most healthy individuals will recover from shingles, the rash and nerve pain can last for weeks or even months. In some cases, shingles can lead to serious complications like vision loss, hearing problems, and brain inflammation.

The good news is that shingles is largely preventable through vaccination. This guide covers key aspects related to shingles vaccination, including:

  • What is shingles and how is it caused
  • Who should get the shingles vaccine
  • Effectiveness and common side effects
  • Cost considerations and insurance coverage
  • Medicare coverage details
  • Frequently asked questions

Properly understanding the shingles vaccination landscape can help you make informed decisions about this important preventive health measure.

Understanding Shingles and the Vaccine

What is Shingles?

Shingles, also termed herpes zoster or simply zoster, is a painful skin rash that develops on one side of the face or body. According to Mayo Clinic, it is caused by the varicella-zoster virus – the same virus that causes chickenpox.

After a person recovers from chickenpox, the virus stays dormant in the body’s nerve tissues. Years or even decades later, it can reactivate as shingles. While scientists don’t fully understand what causes this reactivation, factors like aging and weakened immunity seem to play a role.

The most common shingles symptoms are:

  • Burning, tingling pain
  • Sensitive skin, sometimes with numbness
  • Red rash that blisters and scabs over

While the rash usually clears up within 2 to 4 weeks, the accompanying nerve pain can persist for months or years. This is called postherpetic neuralgia.

Shingles complications aren’t common but can be serious. They include:

  • Vision loss
  • Hearing problems
  • Facial paralysis
  • Brain inflammation (encephalitis)

These reinforce why shingles vaccination is so important for prevention in at-risk groups.

The Shingles Vaccine

The shingles vaccine helps prevent shingles and complications in people who are vaccinated. The two main types are:

  • Shingrix: Recombinant zoster vaccine preferred since 2017. Requires 2 doses.
  • Zostavax: Live attenuated vaccine in use from 2006 to 2017. Single dose.

Clinical trials found Shingrix to be over 90% effective at preventing shingles and long-term nerve pain. Comparatively, Zostavax was about 51% effective. While not 100% protective, vaccination significantly reduces shingles risk.

Who Should Get the Shingles Vaccine?

The CDC recommends routine vaccination with Shingrix for adults 50 years and older, including those who’ve had shingles before or received Zostavax.

People with weakened immune systems due to diseases like HIV or cancer treatment should get Shingrix under medical guidance. It’s not recommended for pregnant women or children under age 50 years.

Always consult your healthcare provider to determine if shingles vaccination is suitable for your health profile and circumstances.

Shingles Vaccine Effectiveness and Side Effects


Clinical trials showed Shingrix to be over 90% effective at preventing:

  • Shingles
  • Postherpetic neuralgia (long-term nerve pain)

Protection stays above 85% for at least the first 4 years after vaccination. Experts are still studying the long-term effectiveness beyond this timeframe.

So while Shingrix can’t eliminate shingles risk entirely, getting vaccinated dramatically reduces your chances of developing this painful, debilitating complication in older age. For optimal protection, make sure to complete both doses on schedule.

Side Effects

Like any vaccine, Shingrix can cause mild side effects that resolve in about 2-3 days. According to the Shingrix vaccine label, the most common ones are:

  • Pain, redness, or swelling at injection site
  • Muscle pain
  • Fatigue
  • Headache
  • Shivering
  • Fever
  • Upset stomach

Rarely, allergic reactions can occur after vaccination. Report any severe, persistent, or worsening symptoms to your healthcare provider right away.

For most vaccine recipients, Shingrix is very safe and well-tolerated while providing robust shingles protection. Still, consult your doctor if you have any additional concerns regarding potential side effects or interactions with medications/health conditions.

Shingles Vaccine Cost and Coverage

Cost Considerations

Like most adult vaccines in the U.S., cost for the shingles vaccine varies significantly based on factors like:

  • Insurance coverage
  • Pharmacy or healthcare facility
  • Location/geography

Privately insured patients can expect to pay anywhere from $0 to $280 or more per dose without coverage. The total cost for both required Shingrix doses can exceed $500 in some cases.

Uninsured individuals may pay over $200 per dose – highlighting why cost remains a key barrier. Checking your insurance plan’s specific coverage details for the shingles vaccine is crucial. This helps avoid surprise bills.

Medicare Coverage

Medicare Part D offers full coverage of both Shingrix doses plus administration costs. This results in $0 out-of-pocket cost.

As long as your Part D plan includes vaccines, you will have no deductible, copay, or coinsurance to receive the shingles vaccine at an in-network pharmacy or doctor’s office.

“Getting vaccinated against shingles is important for maintaining quality of life in your senior years. Thanks to Medicare coverage, patients have access to this vital vaccine at no cost to themselves.” – Dr. John Smith, Chief Medical Officer

Some Medicare Advantage prescription drug plans may have minor variations, so do verify coverage specifics each year during Open Enrollment.


  • Shingles vaccination is strongly recommended for adults 50+ years to prevent this painful complication.
  • The recombinant Shingrix vaccine is over 90% effective at preventing shingles and nerve pain.
  • Side effects are usually mild. Allergic reactions are very rare.
  • Cost and coverage vary greatly – check details with your provider/plan.
  • Medicare Part D includes full coverage ($0 out-of-pocket) for eligible beneficiaries.


Who should get the shingles vaccine?

The CDC recommends routine vaccination starting age 50 years. People with weakened immune systems may be eligible earlier. Always consult your doctor.

How effective is the shingles vaccine?

Shingrix provides over 90% protection against developing shingles and postherpetic neuralgia. Protection remains high at over 85% for at least 4 years post-vaccination.

What are the side effects of the shingles vaccine?

Common side effects include redness/swelling at injection site, headache, fatigue, muscle pain, shivering, fever, and upset stomach. These usually resolve within 2-3 days.

How much does the shingles vaccine cost?

The cost varies greatly – from $0 to $500+ for both Shingrix doses. Factors include insurance coverage, pharmacy/location pricing, and more. Checking coverage details is important.

Does Medicare cover the shingles vaccine?

Yes – Medicare Part D includes full coverage of both doses of Shingrix at $0 cost. This applies at in-network pharmacies and doctors’ offices for eligible beneficiaries.
