Yes, it is possible to get shingles after vaccination, but the vaccine significantly reduces risk and severity.
Understanding the Shingles Vaccine and Its Effectiveness
Shingles, also known as herpes zoster, is a painful skin rash caused by the reactivation of the varicella-zoster virus—the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus lies dormant in nerve tissue near the spinal cord and brain. Years later, it can reactivate as shingles. The vaccine aims to prevent this reactivation or reduce its severity.
There are two main shingles vaccines approved for use: Zostavax and Shingrix. Zostavax, a live attenuated vaccine, was introduced first but has largely been replaced by Shingrix due to better efficacy. Shingrix is a recombinant subunit vaccine that triggers a strong immune response without containing live virus.
While these vaccines are highly effective, no vaccine offers 100% protection. This means you can still get shingles after vaccination, but your chances are much lower. Moreover, if shingles does develop post-vaccine, symptoms tend to be milder with fewer complications.
How Effective Are Shingles Vaccines?
Clinical trials and real-world studies show that Shingrix provides about 90% protection against shingles across all age groups over 50. It also reduces the risk of postherpetic neuralgia (PHN), a common and often debilitating complication causing long-lasting nerve pain.
Zostavax offers about 51% protection against shingles and 67% against PHN but tends to lose effectiveness over time. That’s why Shingrix is now preferred.
Effectiveness can vary depending on individual factors like age, immune system status, and time elapsed since vaccination. Older adults or immunocompromised individuals might see slightly reduced protection but still benefit significantly compared to being unvaccinated.
Vaccine Effectiveness Over Time
Protection from the shingles vaccine isn’t permanent. Studies suggest:
- Shingrix: Maintains high effectiveness (above 85%) for at least four years after vaccination.
- Zostavax: Effectiveness declines more rapidly; protection can drop below 40% after five years.
This waning immunity means some vaccinated individuals may experience shingles later in life. However, even then, symptoms tend to be less severe.
The Reasons Behind Breakthrough Shingles Cases
A “breakthrough” case means developing shingles despite being vaccinated. Several factors contribute:
1. Waning Immunity
As immunity fades over time, dormant varicella-zoster virus may reactivate. This is more common with older vaccines like Zostavax or in people vaccinated many years ago.
2. Immune System Variability
Individual immune responses differ widely due to genetics, overall health, or medications that suppress immunity (e.g., chemotherapy or steroids). These factors can reduce vaccine effectiveness.
3. Age-Related Immune Decline
Aging naturally weakens immune defenses—a process called immunosenescence—making older adults more susceptible even after vaccination.
4. Underlying Medical Conditions
Chronic diseases such as diabetes or HIV can impair immune function and increase breakthrough risk.
Symptoms and Severity of Shingles After Vaccination
If shingles occurs post-vaccination, symptoms generally appear less severe than in unvaccinated cases:
- Milder rash: Fewer blisters that heal faster.
- Reduced pain intensity: Less nerve pain during outbreak.
- Lower risk of complications: Especially postherpetic neuralgia.
Vaccinated individuals tend to recover quicker and experience fewer hospitalizations related to shingles complications.
The Role of Postherpetic Neuralgia (PHN) in Vaccine Impact
PHN is nerve pain persisting long after the rash clears—sometimes months or years—and it’s notoriously difficult to treat. Vaccines have shown remarkable success in reducing PHN incidence:
| Vaccine Type | Reduction in PHN Risk | Duration of Protection |
|---|---|---|
| Zostavax | About 67% | Up to 5 years (efficacy decreases) |
| Shingrix | Around 90% | At least 4 years (ongoing studies) |
| No Vaccine | N/A (baseline risk) | N/A |
Reducing PHN is critical because it severely impacts quality of life for many seniors who develop shingles.
The Importance of Timing for Vaccination
Timing plays a crucial role in maximizing benefits from the shingles vaccine:
- Ages 50 and older: CDC recommends vaccination starting at age 50 regardless of past chickenpox history.
- If you’ve had shingles before: Vaccination is still advised because it helps prevent future episodes.
- If immunocompromised: Consult your doctor; newer guidelines support vaccinating many immunocompromised individuals safely with Shingrix.
- If previously vaccinated with Zostavax: Receiving Shingrix later provides stronger protection.
Getting vaccinated before any signs of weakened immunity or advanced age ensures longer-lasting protection.
The Science Behind Why Vaccines Don’t Guarantee Complete Immunity
Vaccines train your immune system to recognize and fight specific pathogens effectively but don’t eliminate all risks entirely because:
- The varicella-zoster virus remains dormant inside nerves—hidden from direct immune attack.
- Your immune response varies based on genetics and health status.
- The virus can sometimes evade immune defenses even after vaccination.
- No vaccine is perfect; some level of breakthrough infections always exists.
Hence, vaccines act as powerful shields rather than impenetrable walls against disease.
Treatment Options if You Get Shingles After Vaccination
If you develop shingles despite vaccination, prompt treatment helps reduce symptoms:
- Antiviral medications: Drugs like acyclovir or valacyclovir shorten duration and lessen severity when started early (within 72 hours).
- Pain management: Over-the-counter pain relievers or prescription nerve pain medications help control discomfort.
- Corticosteroids: Sometimes prescribed to reduce inflammation but used cautiously.
- Caring for rash: Keep affected area clean and dry; avoid scratching to prevent infection.
Early medical attention remains vital regardless of vaccination status.
The Public Health Impact of Widespread Vaccination Against Shingles
Vaccinating large populations has dramatically lowered overall incidence rates of shingles and related complications worldwide:
- Lowers healthcare costs: Fewer doctor visits, hospital stays, and long-term treatments needed for PHN.
- Makes outbreaks less common: Reduced viral reactivation lowers transmission risks indirectly.
- Puts less strain on caregivers: Milder cases mean less disability among elderly family members who often require assistance during illness.
- Saves lives indirectly: Complications like bacterial infections secondary to rash can be fatal in vulnerable people; vaccines help prevent these outcomes.
Widespread acceptance boosts community-wide immunity benefits beyond individual protection.

Frequently Asked Questions
Can You Still Get Shingles If You Had The Vaccine?
Yes, it is possible to get shingles even after vaccination. The vaccine greatly reduces the risk and severity but does not provide 100% protection. Some people may experience “breakthrough” shingles due to waning immunity or other factors.
How Effective Is The Shingles Vaccine In Preventing Shingles?
The Shingrix vaccine offers about 90% protection against shingles, while Zostavax provides roughly 51%. Effectiveness varies by age and immune status but generally results in fewer and milder cases when vaccinated.
Why Can You Still Get Shingles After Having The Vaccine?
You can still get shingles after vaccination because no vaccine is completely protective. Immunity can decrease over time, and individual health factors may affect how well the vaccine works.
Does Having The Vaccine Affect The Severity If You Get Shingles?
If shingles occurs after vaccination, symptoms are usually milder with fewer complications. The vaccine helps reduce pain duration and lowers the risk of long-term nerve pain called postherpetic neuralgia.
How Long Does Protection Last After Getting The Shingles Vaccine?
Protection from Shingrix remains strong for at least four years, while Zostavax’s effectiveness declines more rapidly over five years. Waning immunity may lead to shingles later, but severity is typically lessened in vaccinated individuals.
The Bottom Line – Can You Still Get Shingles If You Had The Vaccine?
Yes—you can still get shingles if you had the vaccine—but your odds drop dramatically compared to going unvaccinated. The vaccines available today provide robust defense by priming your immune system against varicella-zoster virus reactivation while reducing severity if breakthrough occurs.
Vaccination remains the best tool for preventing painful outbreaks and serious complications like postherpetic neuralgia. Staying up-to-date with recommended doses ensures maximum lasting benefit throughout your later years.
In summary:
| Main Point | Description |
