The chickenpox vaccine, also called the varicella vaccine or chickenpox jab, has become a key tool in preventing varicella infection. Over 90% of people over the age of 15 in England and Wales are already immune to chickenpox (seropositive for varicella-zoster immunoglobulin G). Yet despite widespread natural immunity, serious cases still occur—especially in adults—and vaccination helps reduce that risk.
But does the chickenpox vaccine truly provide lifelong protection, or could its immunity wane over time? Let’s explore how durable that protection is, whether booster doses are ever needed, and how this shapes chickenpox prevention strategies.
What Is the Chickenpox Vaccine, and How Does It Work?
The chickenpox vaccine helps your body build immunity against the varicella-zoster virus, which causes chickenpox. It contains a weakened form of the virus that triggers the immune system to produce protective antibodies without causing illness.
How Many Doses Are Needed?
Most people receive two doses for the best protection. The first dose is usually given in childhood, with a second dose several years later. Adults who have never had chickenpox or the vaccine can also receive two doses for full immunity.
Who Should Get the Chickenpox Jab?
The chickenpox jab is suitable for both children and adults who have not had chickenpox before. It is especially recommended for:
- Healthcare or childcare workers
- Travellers to countries where chickenpox exposure risk is high
- ‘Adults who are around newborns, pregnant women, or immunocompromised individuals
Our pharmacists can advise whether the vaccine is appropriate for you based on your medical history and lifestyle.
How Long Does the Chickenpox Vaccine Last?
Research shows that the chickenpox vaccine provides long-lasting immunity for most people. Protection usually lasts for at least 10 to 20 years and may continue much longer for many people.
Does the Protection Fade Over Time?
While the immunity may slightly decline with age, breakthrough infections are usually mild. People who have received both doses rarely develop severe chickenpox. Booster doses are not routinely recommended in the UK, as studies show lasting protection for the majority of vaccinated individuals.
What Affects Chickenpox Vaccine Immunity Duration?
Several factors can influence how long your immunity lasts, including:
- Your age at vaccination
- Whether you completed both doses
- Your immune system strength
- Overall health and exposure risk
If you are unsure about your immunity, a blood test can check whether you are still protected.
Can Adults Get Chickenpox Even After Vaccination?
Breakthrough cases of chickenpox can occur, but they are generally mild with fewer spots and faster recovery. The vaccine also helps prevent serious complications such as pneumonia or skin infections, which are more common in chickenpox in adults. These mild cases still provide a natural boost to immunity, helping maintain long-term protection.
How Does Vaccination Help Prevent Shingles?
Getting vaccinated against chickenpox may help lower the chance of developing shingles later in life, although evidence on this link is still limited. This is because the immune system is already trained to recognise and fight the varicella-zoster virus.
What Are the Side Effects of the Chickenpox Vaccine?
Like most vaccines, the chickenpox jab can cause mild side effects that usually settle quickly. These may include:
- Redness or soreness at the injection site
- Low-grade fever
- Mild rash
Serious side effects are rare. If you have a weakened immune system, are pregnant, or have an allergy to gelatin or neomycin, you should speak to our pharmacist before vaccination.
What Is the Chickenpox Vaccine Cost in the UK?
The chickenpox vaccine is not part of the routine NHS vaccination schedule, but it is available privately. The chickenpox vaccine cost can vary depending on the pharmacy and location. At Touchwood Pharmacy, the vaccine is offered at competitive prices, and appointments are quick and convenient.
When Should You Consider the Chickenpox Vaccine?
You should consider the vaccine if:
- You have never had chickenpox and work with children or vulnerable adults.
- You are planning pregnancy and are unsure of your immunity.
- You are travelling abroad where exposure risk is higher.
Our pharmacists can provide personalised advice to help you decide whether vaccination is right for you.
How Can You Protect Yourself and Others?
Vaccination remains the most effective way to prevent chickenpox and stop its spread. Good hygiene and avoiding close contact with infected individuals can further reduce your risk.
If you or your child have not had chickenpox, the vaccine offers reliable and long-lasting protection that helps prevent both illness and complications.

FAQs
How long does the chickenpox vaccine last in adults?
In most adults, the chickenpox vaccine provides protection for at least 10 to 20 years. Studies suggest that many people remain immune for life, especially after receiving both doses. If you are unsure of your immunity, a blood test can check your antibody levels.
Do I need a booster after getting the chickenpox vaccine?
Booster doses are not routinely recommended in the UK because two doses of the varicella vaccine provide long-term protection. However, if you were vaccinated many years ago and are at higher risk of exposure, our pharmacists may recommend a booster after assessing your immunity.
Can you still catch chickenpox after having the vaccine?
Breakthrough infections can happen, but they are usually very mild. People who have been vaccinated typically get fewer spots, recover faster, and are far less likely to develop complications compared to those who are unvaccinated.
Is the chickenpox vaccine recommended for adults who never had chickenpox?
Yes, adults who have never had chickenpox can and should be vaccinated. Chickenpox in adults can be more severe and cause complications such as pneumonia. The vaccine offers strong protection and helps prevent both chickenpox and potential shingles later in life.
Does the chickenpox vaccine protect against shingles?
The chickenpox vaccine lowers the risk of developing shingles later in life by reducing the likelihood of the virus remaining dormant in your body. However, it does not completely eliminate the risk. There is a separate shingles vaccine for adults over 50 that provides additional protection.
How much does the chickenpox vaccine cost in the UK?
The chickenpox vaccine is not routinely available on the NHS for everyone, but you can get it privately. The chickenpox vaccine cost varies depending on the pharmacy and region. At Touchwood Pharmacy, you can book a quick, affordable appointment with our pharmacists for full protection.
