Keeping Your Little Ones Safe: Chickenpox Facts & Vaccine Advice

6th January 2026

What is Chickenpox?

Chickenpox is a common and highly contagious infection caused by the varicella zoster virus. In children, it often starts with a day or two of mild fever and feeling a bit under the weather, followed by the appearance of a blistering rash that usually lasts around a week.

For most children, chickenpox is a mild illness. However, in some cases it can lead to more serious complications, such as infections or inflammation of the lungs or brain. Serious complications are rare, but this is why vaccination is an important way to protect your child.

Why Is the Chickenpox Vaccine Important?

  • Prevents serious complications listed above
  • Reduces the risk of hospitalisation and death by more than 90%
  • Prevents shingles in later life
  • Protects others including new-borns, pregnant women and immunocompromised people

The Vaccine

The vaccine contains a live, weakened form of the varicella-zoster virus and it’s designed to help the body build immunity without causing the disease.

It is highly effective – providing about 98% protection in children and significantly reduces the risk of severe illness. It is given as two doses in the upper arm or thigh at least 4 weeks apart.

What to Expect After

Most children tolerate it well and have no side effects but possible mild side effects that may occur include:

  • Soreness or redness at the injection site
  • Mild fever
  • Mild rash (rare)
