Yes, you should receive the Shingrix vaccine even if you've already had shingles.
Having had shingles does not protect you from getting it again, and vaccination with the recombinant zoster vaccine (Shingrix/RZV) is recommended to prevent recurrence. The most recent 2024 Taiwan guidelines explicitly recommend vaccination after a prior episode of herpes zoster, based on high rates of recurrence 1. Multiple international guidelines support this approach 2.
Key Recommendations
Timing After Shingles Episode
- Wait at least 2 months after your shingles episode has completely resolved before getting vaccinated 1
- This 2-month interval is based on the documented minimum time between initial shingles and recurrence
- Different countries recommend varying intervals (2 months to 1 year), but the consensus supports at least 2 months 1
Why Vaccination Still Matters After Having Shingles
Shingles can recur. The evidence shows:
- People who've had shingles once are at risk for another episode
- The recombinant zoster vaccine (Shingrix) does NOT increase your risk of recurrence—in fact, a 2025 phase 3 trial found zero confirmed HZ recurrence cases in vaccinated participants versus 8 cases in placebo recipients 3
- The vaccine is specifically indicated for adults ≥50 years regardless of prior shingles history 4
Vaccine Effectiveness and Safety
The 2-dose Shingrix series provides:
- 97.2% efficacy in preventing shingles in adults ≥50 years 1
- 91.3% efficacy in adults ≥70 years 1
- Protection maintained above 83% for up to 8 years 1
- No increased risk of serious adverse events compared to placebo 1
Common side effects include injection-site reactions (pain, redness, swelling), myalgia, and fatigue—these are typically mild to moderate and transient 1, 5.
Important Caveats
One Notable Exception
A 2024 study found that patients with a history of herpes zoster ophthalmicus (HZO) specifically—shingles affecting the eye—had a slightly increased risk of HZO recurrence within 56 days after RZV vaccination (adjusted hazard ratio 1.64) 6. If you had shingles involving your eye, discuss closer monitoring with your provider after vaccination.
Standard Vaccination Schedule
- Two doses given 2-6 months apart (minimum 4 weeks if needed) 2
- Complete both doses for optimal protection
- Shingrix is preferred over the older live vaccine (Zostavax) 1, 2
Bottom Line Algorithm
- Had shingles? → Wait until acute symptoms completely resolve
- Wait at least 2 months from resolution
- Get Shingrix dose 1
- Get Shingrix dose 2 at 2-6 months after dose 1
- Exception: If you had eye involvement (HZO), arrange follow-up monitoring for 8 weeks post-vaccination
The evidence strongly supports vaccination after prior shingles to prevent future episodes and their complications, particularly postherpetic neuralgia (chronic pain) 1, 3.
