When Do Kids Get the Chickenpox Vaccine?

Chickenpox (varicella) is a common childhood illness that used to affect nearly every child before vaccines were available. Today, thanks to safe and effective vaccines, most kids are protected against chickenpox. Understanding when do kids get chickenpox vaccine and how many doses they need helps parents plan their child’s immunizations with confidence.

Why Vaccinate Against Chickenpox?

• Chickenpox can cause an itchy rash, fever, and discomfort.
• Complications (though rare) include bacterial infections of the skin, pneumonia, and—in severe cases—hospitalization.
• Vaccination not only protects your child but also helps prevent the spread of chickenpox to those who can’t be vaccinated (e.g., infants, pregnant people, or immunocompromised individuals).

Credible sources such as the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) recommend routine vaccination for children.

Recommended Schedule: When Do Kids Get the Chickenpox Vaccine?

According to CDC guidelines, the routine schedule for healthy children is:

1. First dose
   • Age: 12 to 15 months
   • Administered as part of your child’s well-baby visit
2. Second dose
   • Age: 4 to 6 years
   • Usually given before starting kindergarten or first grade

For unvaccinated children or those with uncertain vaccination history:

• Ages 7–12 years: Two doses, 3 to 8 weeks apart.
• Ages 13 years and older: Two doses, 4 to 8 weeks apart.

Older teens and adults who’ve never had chickenpox or the vaccine should also get two doses, 4 to 8 weeks apart.

How Many Doses Are Needed?

The typical dosing schedule is:

• Total doses: 2
• Interval between doses (for catch-up groups):
  • Ages 7–12: 3–8 weeks
  • Ages 13 and up: 4–8 weeks

Why two doses?

• The first dose primes the immune system.
• The second dose boosts immunity, ensuring long-lasting protection.

Studies show over 90% effectiveness after two doses, compared to about 80–85% after just one.

What to Expect at Each Dose

First Dose (12–15 Months)

• Administered by intramuscular injection (usually in the thigh).
• Mild side effects in some children:
  • Soreness or redness at injection site
  • Low-grade fever
  • Mild rash (rare)

Second Dose (4–6 Years)

• Given in the upper arm.
• Similar side-effect profile as the first dose.
• Parents often find their child feels only a little cranky or tired if they notice any reaction at all.

Side effects are generally mild and short-lived. Serious reactions are very rare.

Catch-Up Vaccination for Older Children

Children who missed routine doses can catch up:

• 7–12 years:
  • Dose 1 at any time
  • Dose 2, 3–8 weeks later
• 13 years and older:
  • Dose 1 at any time
  • Dose 2, 4–8 weeks later

Check with your pediatrician or local health department to confirm timing and availability.

Special Considerations

• Immunocompromised children:
  Live vaccines (like varicella) may not be recommended. Talk with a specialist.
• Pregnancy:
  Women should complete vaccination at least one month before becoming pregnant. The vaccine is not given during pregnancy.
• Outbreak settings:
  In some daycare or school outbreaks, health authorities may recommend earlier vaccination for certain age groups.

Addressing Common Concerns

• “Is the vaccine safe?”
  Yes. Decades of monitoring show varicella vaccines are both safe and effective.
• “Can my child still get chickenpox after vaccination?”
  Breakthrough cases can occur but are usually much milder—fewer blisters, lower fever, and quicker recovery.
• “What if my child has an egg allergy?”
  The chickenpox vaccine does not use egg proteins. Allergy to eggs is not a contraindication.

Helpful Tips for Parents

• Keep an updated immunization record.
• Schedule vaccine visits along with other well-child appointments.
• Monitor for mild side effects: cool cloth, acetaminophen (per pediatrician guidance).
• Report any concerning reactions to your doctor immediately.

If your child develops a fever, rash, or unusual symptoms after vaccination, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker. It can help you decide if you need to seek medical care.

When to Speak to a Doctor

While most reactions are mild, always reach out if your child experiences:

• High fever (above 104°F/40°C)
• Severe rash or swelling beyond the injection site
• Difficulty breathing, wheezing, or other signs of an allergic reaction
• Signs of infection at the injection site (redness, warmth, pus)

For any life-threatening or serious symptoms, seek emergency care. For other concerns, your pediatrician or family doctor can provide personalized guidance.

Final Thoughts

Vaccinating your child against chickenpox is a proven way to protect them from an uncomfortable illness and its potential complications. By following the recommended schedule—first dose at 12–15 months and second dose at 4–6 years—you’ll help ensure your child’s immunity is strong and long-lasting.

Don’t hesitate to:

• Talk to your child’s doctor about any questions
• Use the Ubie Symptom Checker for quick guidance on post-vaccine symptoms
• Keep vaccination records handy for school or daycare requirements

Speak to a doctor about anything that could be life threatening or serious. Your pediatrician is the best resource for tailoring vaccine plans to your child’s health needs. By staying informed and proactive, you’re giving your child a healthier start.
