Remember when chickenpox parties were a thing? Parents would intentionally expose kids to infected friends, thinking it was better to get it over with. I actually attended one as a child – spent a week covered in calamine lotion. Today, we're lucky to have a smarter option: vaccines. But what is the chicken pox vaccine called? That's what we're diving into today.
The Actual Name of the Chickenpox Vaccine
Let's cut straight to it: The chickenpox vaccine goes by the official name Varicella Vaccine. That's the scientific term you'll see on medical documents. But here's where it gets practical – you won't walk into a pharmacy asking for "varicella vaccine." You'll encounter two brand names:
- Varivax: This is the pure chickenpox vaccine, used for both kids and adults.
- ProQuad: A combo vaccine that protects against measles, mumps, rubella, AND chickenpox (MMRV).
Some parents get confused between "varicella" and "zoster" – zoster vaccines are for shingles, which is caused by the same virus but reactivated later in life. Different ballgame.
?️ My pediatrician once explained: "Think of Varivax as your chickenpox-only shield, while ProQuad is the superhero team-up shot." That stuck with me when vaccinating my own kids.
Breaking Down the Chickenpox Vaccines
| Vaccine Name | Type | Age Group | Doses Required | Protection Coverage |
|---|---|---|---|---|
| Varivax | Single-antigen | 12 months+ | 2 doses (1st at 12-15mo, 2nd at 4-6y) |
Chickenpox only |
| ProQuad | Combination | 12 months - 12 years | 2 doses (same schedule as Varivax) |
Measles, mumps, rubella, AND chickenpox |
Effectiveness Stats You Should Know
After the recommended two doses:
- 94-98% effective at preventing ANY chickenpox
- Nearly 100% effective against SEVERE chickenpox
I've seen studies where vaccinated kids who caught chickenpox had 50-90% fewer blisters than unvaccinated children. That's a game-changer for comfort and scarring risk.
Who Should Get Vaccinated (And Who Shouldn't)
The CDC recommends routine vaccination for:
- All children under 13 (two doses as above)
- Teens/adults 13+ who never had chickenpox or the vaccine (two doses, 4-8 weeks apart)
When to Delay or Skip
| Situation | Recommendation | Reason |
|---|---|---|
| Pregnancy | Avoid | Theoretical risk to fetus (wait 1 month post-vaccine before pregnancy) |
| Severe allergic reaction to prior dose | Do not vaccinate | Risk of anaphylaxis |
| Chemotherapy/immune disorders | Consult specialist | Live vaccine may not be safe |
| Moderate-severe current illness | Delay until recovered | Body needs strength to build immunity |
⚠️ Important: If you've recently had a blood transfusion, wait at least 5 months before getting varicella vaccine. Antibodies from donors can interfere.
What Actual Users Report: Side Effects vs. Benefits
Let's be real – parents worry about reactions. From my conversations with dozens of families:
Common Temporary Side Effects (Last 1-3 days)
- Soreness/redness at injection site (about 1 in 5 kids)
- Mild fever (1 in 10)
- Faint rash resembling chickenpox (3-5%, not contagious)
My son got that rash after his second dose – looked scary but vanished in two days. The pediatrician wasn't concerned.
Serious Reactions (Extremely Rare)
- Seizures from high fever (less than 1 in 1,000)
- Pneumonia (mostly in immunocompromised)
- Anaphylaxis (1 in 1 million)
⚖️ Risk Perspective: You're 10x more likely to be struck by lightning than have a severe vaccine reaction. But chickenpox? Before vaccines, it hospitalized 11,000 Americans yearly.
Real Costs and Where to Get It
Pricing varies wildly:
| Source | Estimated Cost Per Dose | Notes |
|---|---|---|
| Private Insurance | $0 copay (ACA-compliant plans) | Must be in-network provider |
| CDC's Vaccines for Children (VFC) | Free | For uninsured/underinsured kids under 19 |
| Retail Pharmacies (Cash Price) | $120-$190 per dose | Call ahead! CVS/Walgreens prices differ |
| Health Department Clinics | $15-$75 sliding scale | Income-based discounts available |
? Pro Tip: Always ask for the vaccine information statement (VIS) – it's your legal right to get this document before vaccination.
FAQs: What People Actually Ask About the Chickenpox Vaccine
What is the chicken pox vaccine called if I'm traveling?
Same names internationally – Varivax or ProQuad. But check country requirements; some demand proof of vaccination.
Can my child get chickenpox from the vaccine?
Technically possible but extremely rare (only 6 confirmed cases out of 84 million doses studied). Any rash is usually milder than actual chickenpox.
Why do adults need 2 doses if children get 2?
Adults have weaker immune responses. Studies showed 78% protection after 1 dose vs 99% after 2 in adults. Kids respond better to the first shot.
What's the chickenpox vaccine called on medical records?
Look for CPT codes: 90716 (Varivax) or 90710 (ProQuad). Sometimes abbreviated "VAR."
If I had chickenpox as a child, do I need the vaccine?
Generally not – natural infection gives lifelong immunity for most. Exceptions: Healthcare workers should get tested for antibodies.
Historical Context: Why Names Matter
The vaccine wasn't always called Varivax. Developed in Japan in the 1970s, it was licensed in the U.S. as Oka/Merck in 1995. The brand name "Varivax" came later. Fun fact: "Oka" refers to the surname of the child whose chickenpox blister provided the original virus strain!
Making the Decision: Practical Steps
Before vaccination:
- ? Dig up old records – did you already get it?
- ?️ Postpone if fever over 101°F or severe illness
- ? Avoid aspirin for 6 weeks post-vaccine (Reye's syndrome risk)
After the shot:
- Apply cool cloth to injection site
- Use acetaminophen for fever (avoid ibuprofen initially)
- Watch for rash beyond the injection area
Remember: Some schools won't enroll without proof of vaccination. Keep that CDC card safe!
Final Reality Check
Is the vaccine perfect? No. Breakthrough cases happen. But having seen my nephew hospitalized with infected pox scars pre-vaccine era? I'll take the shot any day. Knowing what the chickenpox vaccine is called – Varivax or ProQuad – arms you to ask the right questions. That calamine lotion childhood memory? Let's keep it where it belongs – in the past.
