Frequently Asked Questions
Does Medicare cover the shingles vaccine?
Yes — Medicare Part D covers the Shingrix (recombinant zoster vaccine) shingles vaccine. Unlike most preventive vaccines covered under Part B at $0, Shingrix is covered under Part D, meaning your cost-sharing depends on your specific plan. With Extra Help or certain Part D plans, Shingrix may be available at low or no cost.
How much does Shingrix cost with Medicare?
Shingrix cost with Medicare Part D varies by plan. Without Extra Help, you may pay $0–$50 per dose depending on your plan's formulary tier and your stage in the benefit period. With Extra Help (Low Income Subsidy), Shingrix is available at a minimal copay. Some Medicare Advantage plans cover Shingrix at $0.
Why is Shingrix covered under Part D instead of Part B?
Medicare covers most preventive vaccines under Part B at $0. However, Shingrix is covered under Part D because it is self-administered — meaning it can be administered by a pharmacist rather than only in a physician's office. This categorization determines which Medicare part covers it.
How effective is Shingrix for seniors?
Shingrix is over 97% effective at preventing shingles in adults 50–69 and about 91% effective in adults 70 and older. It is a two-dose series given 2–6 months apart. The older Zostavax vaccine (no longer available in the US) was only 51–68% effective. Shingrix is the only recommended shingles vaccine.
Do I need Shingrix if I already had shingles?
Yes — the CDC recommends Shingrix even if you have already had shingles, because you can get shingles more than once and the vaccine significantly reduces recurrence risk. You should wait until the shingles rash has fully resolved before getting vaccinated.
Shingles (herpes zoster) affects approximately 1 in 3 Americans over 60 — causing an intensely painful rash that can last weeks, and a complication called postherpetic neuralgia that causes burning nerve pain lasting months or years. The Shingrix vaccine is over 91% effective at preventing shingles in seniors — but its coverage under Medicare Part D rather than Part B confuses many people about costs. Here is everything you need to know.
What Is Shingles and Why Is It Serious
Shingles is caused by the reactivation of the varicella-zoster virus — the same virus that causes chickenpox. After you recover from chickenpox, the virus remains dormant in nerve tissue. As the immune system weakens with age, the virus can reactivate decades later as shingles.
The shingles rash typically appears as a painful stripe of blisters wrapping around one side of the torso, though it can affect the face and eye (herpes zoster ophthalmicus — which can cause vision loss). The pain is often described as burning, stabbing, or electric-shock-like — and for some seniors, the nerve pain (postherpetic neuralgia) continues for months or years after the rash heals.
How Medicare Covers Shingrix
This is the most confusing part: unlike flu shots and COVID vaccines covered under Part B at $0, Shingrix is covered under Medicare Part D. Your actual cost depends on your specific Part D plan's formulary and tier placement.
With Original Medicare + Part D
Shingrix is typically placed on Tier 3 or Tier 4 of most Part D formularies. Your cost may range from $0 to $50 per dose (two doses required) depending on your plan. Check your plan's formulary or call member services to ask specifically about Shingrix coverage and your cost-sharing.
With Extra Help (Low Income Subsidy)
If you qualify for Medicare Extra Help, your Shingrix cost is capped at a nominal copay — typically $4.50–$11.20 per dose in 2026. If you are not sure whether you qualify, apply at ssa.gov/extrahelp.
With Medicare Advantage
Many Medicare Advantage plans include Shingrix at $0 or very low copay as a supplemental benefit. Check your plan's Evidence of Coverage or call member services to confirm your Shingrix benefit.
Where to Get Shingrix
Shingrix is available at most major pharmacies — CVS, Walgreens, Rite Aid, Walmart, Costco, and many supermarket pharmacies — as well as at your doctor's office. Getting it at a pharmacy is typically more convenient and often covered directly under your Part D benefit.
Important: Use a pharmacy that is in your Part D plan's preferred network to get the lowest possible copay. If your plan has a preferred pharmacy partner, use that pharmacy for Shingrix to minimize cost-sharing.
The Two-Dose Schedule
Shingrix requires two doses for full protection:
- First dose: Any time you are ready, age 50 or older
- Second dose: 2 to 6 months after the first dose
Both doses are necessary for the high level of protection. Getting only one dose provides substantially less protection. Set a reminder for the second dose before you leave the pharmacy after your first injection.
What to Expect After Shingrix
Shingrix has a higher rate of side effects than many other vaccines — which is actually a sign that it is working. Common side effects include soreness, redness, or swelling at the injection site (very common), fatigue, headache, muscle pain, shivering, fever, and stomach pain (all common, usually lasting 2–3 days). These are temporary and far preferable to shingles itself.
- If you are 50 or older and have not had Shingrix, get it — it is the most effective vaccine available for this age group
- Check your Part D plan's formulary for Shingrix tier and your expected copay before going to the pharmacy
- Use your plan's preferred network pharmacy for the lowest copay
- Schedule your second dose 2–6 months after the first — set a phone reminder before you leave
- If you previously had the Zostavax vaccine, you should still get Shingrix — it is significantly more effective
- If cost is a barrier, apply for Extra Help at ssa.gov — it dramatically reduces your copay
