The Importance of Vaccinating Children Against Chickenpox: JCVI Recommends Including it with MMR Vaccine


Chickenpox is a highly contagious disease caused by the varicella-zoster virus. It primarily affects children but can also occur in adults. While chickenpox is generally considered a mild illness, it can lead to complications and serious health issues, especially in infants, pregnant women, and individuals with weakened immune systems.

To prevent the spread of chickenpox and protect vulnerable populations, the Joint Committee on Vaccination and Immunisation (JCVI) has recommended including the chickenpox vaccine as part of the routine MMR (measles, mumps, and rubella) vaccination in the UK.

This article aims to highlight the importance of vaccinating children against chickenpox and the benefits of combining it with the MMR vaccine.

The Need to Protect Children

Children are particularly susceptible to chickenpox due to their immature immune systems. While it may seem like a harmless childhood infection, it can lead to severe complications, such as bacterial skin infections, pneumonia, encephalitis (inflammation of the brain), and even death.

By vaccinating children against chickenpox, we can significantly reduce the risk of these complications and keep our little ones safe. Moreover, when children are immunized, they also contribute to herd immunity, protecting those who cannot receive vaccines due to medical reasons or compromised immune systems.

The JCVI Recommendation

In their latest guidance, the JCVI recommended combining the chickenpox vaccine with the routine MMR vaccine. This decision was based on extensive research and evidence that support the effectiveness and safety of this approach.

By including the chickenpox vaccine in the MMR vaccination schedule, healthcare providers can administer both vaccines in a single visit, increasing convenience for parents and improving compliance rates. This consolidation also minimizes the risk of missed opportunities for vaccination.

Benefits of Combining Vaccines

When the chickenpox vaccine is combined with the MMR vaccine, children receive protection against three highly-contagious diseases in one dosage. This approach offers the following advantages:

1. Streamlined Vaccination Process: Administering multiple vaccines in a single visit reduces the number of appointments parents need to attend and minimizes the burden on healthcare systems.

2. Improved Compliance: Combining vaccines improves compliance rates as parents do not need to schedule separate appointments for each vaccine. This ensures that a higher percentage of children receive the recommended immunization.

3. Cost-effectiveness: Consolidating vaccines helps reduce healthcare costs associated with vaccine administration, storage, and distribution.

4. Enhanced Herd Immunity: By increasing vaccine coverage for multiple diseases, herd immunity is strengthened, resulting in additional protection for not only vaccinated individuals but also those unable to receive vaccinations.

Evidence of Effectiveness

Numerous studies have demonstrated the effectiveness of the chickenpox vaccine when combined with the MMR vaccine. For example, a study published in the New England Journal of Medicine found that the combined vaccine offered 98% protection against chickenpox in the first year after vaccination.

Another study conducted in the United States showed that the combination vaccine reduced the incidence of chickenpox and related hospitalizations significantly. This data serves as evidence of the vaccine’s ability to prevent the spread of the varicella-zoster virus and its associated complications.

Addressing Concerns

Some parents might have concerns about the safety and potential side effects of vaccines. However, extensive research and monitoring have shown that the chickenpox vaccine, when combined with the MMR vaccine, is safe and well-tolerated.

Most common side effects are mild and temporary, including redness or swelling at the injection site, low-grade fever, and a mild rash. Serious side effects are extremely rare, and the benefits of vaccination far outweigh the risks.

It is essential to consult healthcare professionals and reliable sources of information to address any concerns or misconceptions parents might have about vaccines. Healthcare providers play a crucial role in providing accurate information and dispelling myths surrounding vaccination.


The inclusion of the chickenpox vaccine in the routine MMR vaccination schedule offers numerous benefits in protecting children from a potentially severe and contagious disease. By following the JCVI recommendation and vaccinating children against chickenpox, we can prevent complications, reduce the spread of the virus, and safeguard vulnerable populations.

It is important for parents to understand the effectiveness and safety of vaccines, dispel any concerns or doubts, and make informed decisions for the health and well-being of their children. Vaccines save lives, and through routine immunization, we can create a healthier and safer future for our children.[2]
