Chickenpox Vaccine: Who Should Consider It and Why It Matters
Chickenpox (varicella) is often thought of as a mild childhood illness, but for some people it can lead to serious complications. In the UK, the chickenpox vaccine is available privately and may be recommended in specific circumstances following clinical assessment.
This article explains what chickenpox is, who may benefit from vaccination, and how the vaccine is used safely.
What is chickenpox?
Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus. It commonly causes:
An itchy, blister-like rash
Fever
Fatigue and general malaise
Most people who catch chickenpox develop lifelong immunity. However, the infection can be more severe in adults and in people with weakened immune systems.
Why can chickenpox be serious?
While many children recover without complications, chickenpox can lead to:
Bacterial skin infections
Pneumonia
Encephalitis (inflammation of the brain)
Severe illness in pregnancy, affecting both mother and baby
Adults who did not have chickenpox as children are more likely to experience more severe symptoms.
What is the chickenpox vaccine?
The chickenpox vaccine contains a live attenuated (weakened) form of the varicella virus. It helps the immune system build protection without causing full infection.
In the UK, the chickenpox vaccine is a Prescription Only Medicine (POM) and is supplied following an appropriate clinical assessment.
Who may benefit from the chickenpox vaccine?
Chickenpox vaccination may be recommended for:
Children who have missed the chickenpox childhood vaccination and have never had chickenpox
Adults who have never had chickenpox
Healthcare workers or carers who may be exposed to vulnerable individuals
Household contacts of people with weakened immune systems
People planning to become pregnant who are not immune (vaccination must be completed before pregnancy)
Vaccination decisions should always be based on individual clinical assessment, including medical history and immunity status.
Who should not have the chickenpox vaccine?
Because the vaccine is live, it is not suitable for everyone. It may not be appropriate if you:
Are pregnant or trying to conceive
Have a significantly weakened immune system
Are taking certain immunosuppressive medicines
A healthcare professional will assess suitability before vaccination.
How is the vaccine given?
The standard course usually involves two doses, given several weeks apart, to provide effective long-term protection.
The exact schedule will depend on individual circumstances and clinical guidance.
Is the chickenpox vaccine safe?
The chickenpox vaccine has been used worldwide for many years and is generally well tolerated when given appropriately.
Possible side effects are usually mild and may include:
Soreness at the injection site
Mild fever
A small rash
As with all vaccines, risks and benefits should be discussed during consultation.
Why assessment before vaccination is important
Not everyone who thinks they haven’t had chickenpox is non-immune. Many people had a mild infection in childhood without realising.
Clinical assessment may include:
Reviewing medical history
Discussing previous exposure
In some cases, blood testing to confirm immunity
This helps ensure vaccination is necessary and appropriate.
