Updated: Mar 18

Chickenpox, also known as varicella, is a highly contagious viral infection characterised by itchy red spots that progress into fluid-filled blisters. While often considered a mild childhood illness, chickenpox can lead to complications, particularly in adults and individuals with weakened immune systems. The chickenpox vaccine offers a safe and effective means of preventing this common childhood ailment. Let's explore the importance of the chickenpox vaccine in safeguarding against varicella infection.

Understanding Chickenpox and the Vaccine

Chickenpox is caused by the varicella-zoster virus (VZV), which spreads through respiratory droplets or direct contact with the fluid from the blisters of an infected person. The chickenpox vaccine contains a weakened form of the virus. This stimulates the body's immune response, providing protection against chickenpox without causing the disease itself.

Who Should Get Vaccinated?

The Joint Committee on Vaccination and Immunisation (JCVI) has recommended a vaccine against varicella, commonly known as chickenpox, should be added to the UK’s routine childhood immunisation programme. The first dose is typically administered at age 1, with a second dose given 4-6 weeks later. Vaccination is also recommended for certain high-risk groups, including healthcare workers, college students, and international travellers.

Benefits of Chickenpox Vaccination

  1. Prevention of Infection: The primary benefit of the chickenpox vaccine is its ability to prevent chickenpox infection. Vaccination significantly reduces the risk of contracting the disease and its associated complications, including bacterial skin infections, pneumonia, and encephalitis.

  2. Reduced Disease Burden: By vaccinating children against chickenpox, the burden of illness on families, healthcare systems, and communities can be significantly reduced. Fewer cases of chickenpox mean fewer missed school days, doctor visits, and hospitalisations.

  3. Protection in High-Risk Groups: Vaccination is particularly important for individuals at increased risk of severe complications from chickenpox, such as pregnant women, new-borns, and individuals with weakened immune systems.

Safety and Side Effects

The chickenpox vaccine is considered safe and well-tolerated for the majority of individuals. Common side effects may include soreness at the injection site, mild fever, and rash. Serious side effects are rare but can occur. It's essential to discuss any concerns with a healthcare provider before vaccination.


The chickenpox vaccine plays a crucial role in preventing the spread of varicella infection and protecting individuals from the potential complications of chickenpox. By ensuring routine vaccination for children and targeted vaccination for high-risk groups, we can significantly reduce the burden of chickenpox on public health and well-being.
