Having chickenpox may bring back fond memories of childhood, but it is important not to underestimate the potential severity of this common viral infection. The varicella-zoster virus, a member of the herpes family, is responsible for causing chickenpox, which spreads easily through respiratory droplets, making it highly contagious.
Typically, chickenpox starts with mild cold-like symptoms such as a runny nose and cough, followed by the characteristic itchy rash. Individuals with chickenpox become contagious even before the rash appears and remain contagious until all the lesions have crusted over. While most people recover from chickenpox without complications and develop lifelong immunity, the infection can have severe consequences for some.
Contrary to popular belief, chickenpox is not a harmless condition. The risk of serious complications, though relatively low, exists. Permanent scarring is one possible outcome, but more concerning problems can arise. In rare cases, chickenpox can lead to meningitis or inflammation of the brain, which can result in stroke, disability, or even death.
Fortunately, vaccination provides a safe and effective means of protection against chickenpox. Many countries, including Germany, the US, Canada, and Australia, have already incorporated the varicella vaccine into their childhood immunization schedules. This live-attenuated vaccine utilizes a weakened strain of the varicella virus to stimulate the immune system without causing infection. It has demonstrated an impressive 98% effectiveness in children and teenagers, offering 75% protection in adults.
Some may argue that allowing children to naturally acquire chickenpox is a viable option, as it is often perceived as a mild and self-limiting illness. However, even without considering the potential for serious complications, the discomfort and distress caused by the infection alone should be reason enough to prioritize vaccination.
As a medical professional, I strongly advocate for the inclusion of the varicella vaccine in Ireland’s childhood immunization schedule. The prohibitive cost of approximately €200 for the two required doses should not prevent families from accessing this vital protection for their children. Vaccination not only safeguards against potential complications but also contributes to the overall health and well-being of our communities.

While most cases of chickenpox resolve without complications, serious problems can occur. These include meningitis, inflammation of the brain, and in rare cases, stroke, disability, or death.
4. How effective is the varicella vaccine?
The varicella vaccine has proven to be highly effective, providing up to 98% immunity in children and teenagers. In adults, it offers 75% protection against chickenpox.
5. Why should we vaccinate against chickenpox?
Vaccination not only prevents potential complications such as scarring and severe illness, but it also reduces the discomfort and distress caused by the infection.
