Vaccine (Shot) for Chickenpox

When should my child get the chickenpox shot?

One dose at each of the following ages:

1st Dose
  12 – 15 months
2nd Dose
  4 – 6 years

Why should my child get the chickenpox shot?

  • Protects your child from chickenpox (varicella), a potentially serious and even deadly disease.
  • Keeps your child from missing up to one week of school or childcare (and keeps you from missing work to care for your sick child).

The chickenpox shot is safe.

The chickenpox shot is very safe, and it is effective at protecting against chickenpox. Vaccines, like a medicine, can have side effects. These are usually mild and go away on their own.

What are the side effects?

Most children don’t have any side effects from the shot. The side effects that do occur are usually mild, and may include:

  • Soreness, redness, or swelling where the shot was given
  • Fever
  • Mild rash
  • Temporary pain and stiffness in the joints

Prepare for your child’s vaccine visit and learn about how you can:

  • Research vaccines and ready your child before the visit
  • Comfort your child during the appointment
  • Care for your child after the shots

Chickenpox can be serious

Complications from chickenpox can be serious and can occur in any person who develops chickenpox, although they are more common in healthy babies, adults, and people with weakened immune systems. About 9 out of 10 children who get 2 doses of the vaccine will be completely protected from chickenpox.

Before the vaccine was available, about 4 million people got chickenpox each year in the United States, over 10,500 of those people were hospitalized, and about 100-150 people died.

How does chickenpox spread?

Chickenpox spreads easily, mainly when a person touches or breathes in the virus particles that come from chickenpox.  It can also spread through tiny droplets that get into the air when someone who has chickenpox breathes or talks, for example. Chickenpox can spread 1 to 2 days before the infected person gets a rash until all the blisters have formed scabs.

Why not let my child get chickenpox naturally?

Chickenpox is a mild disease for many children, but not all. There’s no way to know who will have a serious case. When your child gets the chickenpox shots, he or she is getting immunity from chickenpox without the risk of serious complications of the disease.

Follow the vaccine schedule

The Centers for Disease Control and Prevention, American Academy of Family Physicians, and American Academy of Pediatrics strongly recommend children receive all vaccines according to the recommended vaccine schedule.
