How Does the Chickenpox Vaccine Prevent Severe Infections?

how the chickenpox vaccine prevents severe infections

Chickenpox, also known as varicella, is a common illness caused by the varicella-zoster virus. While many people think of it as a mild childhood condition, it can sometimes lead to serious complications—especially in babies, teenagers, adults, and those with weakened immune systems. Thankfully, the chickenpox vaccine helps prevent both the infection and its more dangerous outcomes.

Let’s break down how the chickenpox vaccine works, its benefits, and why it’s worth considering privately.

What is the Chickenpox Vaccine?

The chickenpox vaccine, also known as the varicella vaccine, is a safe and effective way to protect yourself or your child from catching the chickenpox virus. It contains a weakened form of the virus, which helps the body develop immunity without causing illness.

There are usually two doses of the vaccine. The first is given to children after their first birthday, and the second is offered a few weeks or months later to boost protection. For older children, teenagers, and adults who have never had chickenpox or the vaccine, two doses are recommended with at least four weeks in between.

How Does It Work?

When you get the chickenpox vaccine, your immune system reacts by creating antibodies. These are special proteins that fight off the virus if you’re ever exposed in the future. This means that if you do come into contact with someone who has chickenpox, your body can quickly respond and protect you from getting ill.

In most cases, the vaccine provides long-lasting protection, and if a vaccinated person does get chickenpox, the symptoms are usually much milder.

How Effective is the Chickenpox Vaccine?

Chickenpox vaccine effectiveness is quite high. According to studies:

  • One dose is around 80% effective at preventing any chickenpox and 95% effective at preventing severe forms.
  • Two doses increase protection to about 98%.

This means that not only does the vaccine reduce your risk of catching the virus, but it also lowers the chance of complications such as skin infections, pneumonia, swelling of the brain (encephalitis), and scarring.

Who Should Get the Vaccine?

In the UK, the chickenpox vaccine is not part of the routine childhood vaccination schedule on the NHS. However, it is offered free to:

  • People in close contact with someone who has a weak immune system (such as a sibling of a child with cancer).
  • Healthcare workers who haven’t had chickenpox.

For everyone else, the vaccine is available privately. Many parents choose to book chickenpox vaccine appointments at private clinics to ensure their child is protected early.

Is the Vaccine Safe?

Yes, the chickenpox virus vaccine is considered very safe. Side effects are usually mild and may include:

  • A sore arm where the injection was given
  • A mild rash
  • Slight fever

Serious side effects are extremely rare. Most people have no problems at all after being vaccinated.

What if I’ve Already Had Chickenpox?

If you’ve had chickenpox before, your body is likely already immune. However, it’s always best to check with your GP or our pharmacist if you’re unsure. In some cases, people might confuse other rashes or illnesses with chickenpox.
