Chickenpox, also known as varicella, is a contagious viral infection that commonly affects children. While most cases are mild, the disease can cause severe complications in adults and individuals with weakened immune systems. In Singapore, the introduction of the chickenpox vaccine has greatly reduced the incidence of this illness, providing a crucial layer of protection for individuals of all ages. This article provides a comprehensive overview of the chickenpox vaccine Singapore, its importance, and why getting vaccinated is essential for public health.
What is the Chickenpox Vaccine?
The chickenpox vaccine, also known as the varicella vaccine, is a safe and effective way to prevent chickenpox infection. It contains a weakened form of the varicella-zoster virus, which triggers the body’s immune system to create antibodies without causing illness. After receiving the vaccine, individuals develop immunity against chickenpox, reducing the likelihood of contracting the virus and experiencing its symptoms.
The vaccine is typically administered in two doses: the first dose is given at 12 to 15 months of age, and the second dose is given between 4 and 6 years old. In cases where individuals missed these vaccination windows, catch-up vaccinations are available for children, adolescents, and adults.
The Chickenpox Vaccine in Singapore
In Singapore, the chickenpox vaccine is included in the National Childhood Immunisation Schedule (NCIS), which means it is offered for free to eligible children at public healthcare institutions. By vaccinating children early, Singapore aims to prevent outbreaks in schools, kindergartens, and other community settings.
For those who missed vaccination in their early years, such as older children, adolescents, or adults, the vaccine is available at private healthcare clinics and hospitals. The cost for the chickenpox vaccine at private healthcare facilities generally ranges from SGD 70 to SGD 150 per dose. Since two doses are required for full immunity, the total cost typically ranges from SGD 140 to SGD 300, depending on the healthcare provider.
Benefits of the Chickenpox Vaccine
Prevents Chickenpox and Its Complications: Chickenpox can lead to severe complications, especially for adults and individuals with compromised immune systems. These complications may include pneumonia, encephalitis (brain inflammation), and secondary bacterial infections. The vaccine significantly reduces the chances of contracting the disease and experiencing such complications.
Reduces the Risk of Shingles: After a person recovers from chickenpox, the varicella-zoster virus remains dormant in the body and can later reactivate as shingles (herpes zoster). Shingles is a painful condition that primarily affects older adults and can lead to long-lasting nerve pain. The chickenpox vaccine not only prevents chickenpox but also lowers the risk of developing shingles later in life.
Milder Symptoms for Vaccinated Individuals: Even if vaccinated individuals contract chickenpox, the severity of the illness is usually much less than in unvaccinated individuals. Those who have been vaccinated tend to experience fewer rashes, lower fever, and a quicker recovery.
Contributes to Herd Immunity: Widespread vaccination helps protect those who cannot be vaccinated, such as infants, pregnant women, and individuals with weakened immune systems. By lowering the overall prevalence of chickenpox in the community, herd immunity helps prevent outbreaks and protect vulnerable individuals from the virus.
Who Should Get the Chickenpox Vaccine?
The chickenpox vaccine is recommended for:
Children: As part of Singapore’s National Childhood Immunisation Schedule, the chickenpox vaccine is routinely offered to all Singaporean children. The first dose is given at 12 to 15 months of age, and the second dose is given between 4 and 6 years.
Adults and Adolescents: Adults who have never had chickenpox or the chickenpox vaccine should get vaccinated. Chickenpox is generally more severe in adults, and vaccination helps protect against the risks associated with the disease.
Pregnant Women: Pregnant women should not receive the chickenpox vaccine during pregnancy. However, if a woman is planning to become pregnant and has not had chickenpox, she should consult with a healthcare provider for a blood test to determine immunity. If necessary, the vaccine can be administered before conception.
Healthcare Workers: Healthcare professionals who are not immune to chickenpox should get vaccinated to reduce the risk of exposing patients, particularly those who are immunocompromised, to the virus.
Side Effects and Safety of the Chickenpox Vaccine
Like all vaccines, the chickenpox vaccine is generally safe, and serious side effects are rare. Some individuals may experience mild side effects, which are typically short-lived and go away on their own. Common side effects include:
Pain, redness, or swelling at the injection site
Mild fever
A mild rash (in some cases)
Severe allergic reactions are rare but can occur. If you experience unusual symptoms following vaccination, it is important to contact a healthcare professional immediately.
The vaccine is contraindicated for individuals who are allergic to any component of the vaccine or who are immunocompromised. If in doubt, it is essential to speak with a healthcare provider to ensure the vaccine is safe for you or your child.
Cost of the Chickenpox Vaccine in Singapore
For children under the National Childhood Immunisation Schedule, the chickenpox vaccine is free of charge at public healthcare facilities. For individuals who require vaccination later in life, including older children, teenagers, and adults, the vaccine is available at private healthcare providers, where the cost typically ranges from SGD 70 to SGD 150 per dose. A total of two doses are required for complete vaccination, which means the total cost can range from SGD 140 to SGD 300, depending on the healthcare provider and any additional fees for consultation.
Conclusion
The chickenpox vaccine has proven to be an effective tool in reducing the incidence of chickenpox and its complications in Singapore. By preventing the disease, the vaccine also helps reduce the long-term risks of shingles and other serious health issues. With the availability of free vaccination for children through the National Childhood Immunisation Schedule and affordable options for adults, Singapore is making great strides in protecting its population from this once common but preventable illness.
