While most people develop lifelong immunity after having chickenpox once, it is possible—though rare—to get chickenpox twice. The virus that causes chickenpox (varicella-zoster) can also reactivate later in life as shingles, a related but different condition.

Facts About Get Chickenpox Twice
✔ Most people get chickenpox only once (lifelong immunity).
✔ Reinfection is rare but possible, especially in people with weak immune systems.
✔ The same virus can return as shingles (a painful nerve infection).
✔ Vaccination reduces reinfection risk and makes symptoms milder if it happens.
Why Do Most People Only Get Chickenpox Once?
After a chickenpox infection, your body develops antibodies that usually prevent reinfection. The varicella-zoster virus (VZV) stays dormant in your nerves but is kept in check by your immune system.
How Immunity Works
- Primary infection → Body makes memory cells to fight future exposures.
- Virus remains inactive in nerve tissues (doesn’t cause symptoms).
- Strong immune system keeps it from reactivating.
When Can Chickenpox Happen Again?
1. Immune System Weakness
People with compromised immunity (due to illness, medications, or treatments like chemotherapy) may lose protection and get reinfected.
2. Very Mild First Infection
If the first case was extremely mild, the body might not have built strong enough immunity.
3. Vaccinated Individuals
- The chickenpox vaccine is highly effective but not 100% foolproof.
- Some vaccinated people can still get “breakthrough varicella”, but symptoms are usually milder.
Chickenpox vs. Shingles: What’s the Difference?
| Factor | Chickenpox | Shingles |
|---|---|---|
| Cause | First VZV infection | Reactivation of dormant VZV |
| Symptoms | Itchy rash all over body | Painful, blistering rash on one side |
| Contagious? | Yes (spreads chickenpox) | Yes (can spread chickenpox to unvaccinated people) |
| Who Gets It? | Mostly children | Adults (usually 50+ or immunocompromised) |
💡 Note: If you’ve had chickenpox, you cannot get it again, but the virus can return as shingles.
How to Reduce Your Risk?
1. Get Vaccinated
- Chickenpox vaccine (Varivax) – Prevents initial infection.
- Shingles vaccine (Shingrix) – Recommended for adults 50+ to prevent reactivation.
2. Boost Immunity
✔ Eat a balanced diet
✔ Exercise regularly
✔ Manage stress
3. Avoid Exposure
- Stay away from infected people if you’re high-risk.
- Practice good hygiene (washing hands, not sharing utensils).
FAQs
1. How rare is it to get chickenpox twice?
- Very rare (most people are immune after first infection).
2. Can you get shingles if you’ve never had chickenpox?
- No, but you can get chickenpox from someone with shingles if unvaccinated.
3. Are second chickenpox infections worse?
- Usually milder, but can be severe in immunocompromised people.
4. Can blood tests check for immunity?
- Yes, a varicella-zoster antibody test can confirm if you’re protected.
5. Should I get vaccinated if I’ve already had chickenpox?
- Not usually, but the shingles vaccine is recommended for older adults.
Final Verdict
While most people only get chickenpox once, reinfection is possible in rare cases. The best protection is vaccination and maintaining a strong immune system.
⚠️ If you suspect chickenpox or shingles, see a doctor for proper diagnosis and treatment.
