Shingles isn’t just a rash. For many, it’s months of burning pain, sleepless nights, and a risk of lifelong nerve damage called postherpetic neuralgia. The good news? There’s a vaccine that works better than anything we’ve had before. The recombinant zoster vaccine, known as Shingrix, is now the only shingles vaccine available in the U.S. and is recommended for nearly all adults over 50 - and even some younger people with weakened immune systems.
Who Exactly Needs the Shingrix Vaccine?
If you’re 50 or older, you should get Shingrix. No exceptions. That’s the CDC’s clear, unambiguous stance. Age is the biggest risk factor for shingles. By the time you hit 50, your immune system has had decades to slow down, and the varicella-zoster virus - the same one that causes chickenpox - can wake up and cause shingles. About 1 in 3 people in the U.S. will get shingles in their lifetime. The risk keeps climbing with age.
But it’s not just about age. If you’re 19 or older and have a weakened immune system - whether from HIV, cancer treatment, organ transplant, or long-term steroid use - you’re at even higher risk. Shingrix is safe for these groups because it’s not a live virus vaccine. Older vaccines like Zostavax used live virus and couldn’t be given to immunocompromised people. Shingrix doesn’t have that problem. It’s made with a piece of the virus (glycoprotein E) and a powerful adjuvant to boost your immune response. That’s why it’s effective even in people whose immune systems aren’t working at full strength.
Why Shingrix Over Anything Else?
There used to be another option: Zostavax. It was a live vaccine, given as a single shot, and it only prevented about half of shingles cases. It also didn’t work as well in older adults. By 2020, it was pulled from the U.S. market entirely. Today, Shingrix is the only game in town.
Here’s what Shingrix does that Zostavax couldn’t:
- Prevents over 90% of shingles cases in people aged 50-69
- Still works at 91% effectiveness for those 70 and older
- Reduces risk of postherpetic neuralgia by 90% in younger adults and 89% in older adults
- Works for people with autoimmune diseases, cancer, or on immunosuppressants
- Protection lasts at least 7 years - and likely longer
That’s not close to any other vaccine. Shingrix isn’t just better - it’s a major leap forward. If you got Zostavax in the past, you still need Shingrix. The CDC says to wait at least five years after Zostavax before getting Shingrix, but don’t delay. Your protection from Zostavax fades over time, and Shingrix gives you much stronger, longer-lasting defense.
How Is It Given? What to Expect
Shingrix isn’t a one-and-done shot. You need two doses, given 2 to 6 months apart. For people with weakened immune systems, the second dose can be given as early as 1 to 2 months after the first. This isn’t optional - skipping the second shot cuts your protection in half.
The vaccine is injected into your upper arm, same as a flu shot. It’s stored cold and must be mixed right before use. Your provider will know the drill.
Side effects? Yes, they’re common. About 8 out of 10 people feel pain, redness, or swelling at the injection site. Half feel tired, achy, or have a headache. One in six says the side effects were bad enough to miss work or daily activities for a day or two. These aren’t signs of shingles - they’re signs your immune system is waking up and fighting back.
Most side effects go away in 2 to 3 days. If you’ve had shingles before, you’ll probably be more willing to put up with the discomfort. You know what it feels like. If you haven’t had it, the side effects might surprise you. But remember: the pain from shingles can last months or years. The vaccine side effects? They’re over in days.
Who Should Skip It?
Very few people should avoid Shingrix. The only absolute reason not to get it is if you’ve had a severe allergic reaction (like anaphylaxis) to any part of the vaccine or to a previous dose.
If you’re feeling sick right now - say, with a fever or a bad cold - wait until you’re better. That’s a precaution, not a rule. The vaccine itself won’t make you sicker, but your body is already working hard. Better to let it rest before adding a strong immune trigger.
There’s no need to test for chickenpox history. If you were born before 1980, you almost certainly had chickenpox, even if you don’t remember it. And if you’re unsure? Get the vaccine anyway. It won’t hurt you.
Cost and Insurance Coverage
Shingrix costs about $175 for both doses. That sounds steep, but most insurance plans cover it fully. Medicare Part D covers it with no out-of-pocket cost for most people. Private insurers follow the same pattern. If you’re on Medicaid or have no insurance, check with your local health department. Many offer vaccines at low or no cost through public health programs.
Don’t let cost stop you. Shingles can lead to hospital visits, lost work, and long-term nerve pain that costs thousands in treatments and lost wages. The vaccine is a one-time investment that protects you for years.
What If You’re Under 50?
If you’re under 50 and healthy, you don’t need Shingrix yet. But if you’re 19 or older and have a condition that weakens your immune system - like rheumatoid arthritis on biologics, leukemia, or HIV with low CD4 counts - you should get it. The CDC updated its guidelines in 2018 to include this group. These people are at higher risk for severe shingles, and Shingrix is the only safe, effective option for them.
Some younger adults with chronic conditions like diabetes, COPD, or kidney disease are also at increased risk. Talk to your doctor. Even if you’re not in the official recommendation yet, your individual risk might justify getting vaccinated early.
What Happens After You Get It?
Keep your vaccination card. Write down the date of your first dose. Set a reminder for the second dose - six months later. Don’t wait until you’re sick or forgetful. Many people skip the second shot because they feel fine after the first. But without it, your protection drops to about 50%, which is worse than what Zostavax offered.
Even if you’ve had shingles before, you still need the vaccine. Shingles can come back. And when it does, it’s often worse the second time. Shingrix reduces your chance of recurrence by more than 90%.
There’s no booster needed yet. Current data shows protection lasts at least 7 years, and modeling suggests it could last 15 to 20. The CDC is watching closely, but for now, two doses are all you need for life.
Why Isn’t Everyone Getting It?
Only about one-third of adults over 60 have gotten both doses of Shingrix. That’s far below the CDC’s goal of 70%. Why? A few reasons:
- People think they’re not at risk - until they get shingles
- Doctors don’t always bring it up
- The two-dose schedule is harder to complete than a single shot
- Side effects scare some people away
But the science is clear: if you’re eligible, get both doses. The risk of shingles is real. The vaccine works. The side effects are temporary. The consequences of skipping it? Not worth it.
Can I get Shingrix if I’ve already had shingles?
Yes. Even if you’ve had shingles, you should still get Shingrix. The vaccine reduces your risk of getting it again by more than 90%. There’s no required waiting period - you can get it as soon as your rash has cleared and you’re no longer in pain.
Is Shingrix safe for people with autoimmune diseases?
Yes. Unlike older live vaccines, Shingrix is non-live and safe for people with autoimmune conditions like lupus, multiple sclerosis, or rheumatoid arthritis - even if they’re on medications that suppress the immune system. The CDC specifically recommends it for adults 19 and older with these conditions.
How long does Shingrix protection last?
Current data shows protection lasts at least 7 years, and studies suggest it may last 15 to 20 years. There’s no approved booster yet, and experts don’t expect one to be needed within the next decade. The vaccine’s effectiveness remains above 85% even after 7 years.
Can I get Shingrix at the same time as my flu shot or COVID booster?
Yes. Shingrix can be given at the same visit as other vaccines, including flu, COVID-19, and pneumococcal shots. Just use different arms. There’s no evidence this reduces effectiveness or increases side effects.
What if I only got one dose of Shingrix?
You’re not fully protected. One dose gives about 50% effectiveness - less than the old Zostavax vaccine. You need both doses to get the full 90%+ protection. If it’s been more than 6 months since your first dose, get the second one as soon as possible. You don’t need to restart the series.
Is Shingrix covered by Medicare?
Yes. Medicare Part D covers Shingrix with no out-of-pocket cost for most beneficiaries. You can get it at a pharmacy or doctor’s office - just make sure your provider bills your Part D plan. Some pharmacies may require you to use their in-network provider, so check ahead.
Next Steps: What to Do Now
If you’re 50 or older: Call your doctor or local pharmacy. Ask if they have Shingrix in stock. Schedule your first dose. Set a calendar reminder for the second dose six months later.
If you’re 19-49 and have a weakened immune system: Talk to your specialist. Bring up Shingrix. If they’re unsure, ask them to check the CDC guidelines for immunocompromised adults.
If you got Zostavax before: You still need Shingrix. Wait at least five years after your last Zostavax shot, then get the two-dose series. Don’t assume you’re still protected.
Shingles is painful, unpredictable, and sometimes disabling. The vaccine is safe, effective, and widely covered. There’s no reason to wait. Get both doses - your future self will thank you.
