Chickenpox Vaccination Service — Safe & Effective Protection for All Ages
⏱️ 1-Minute Key Takeaways
- Chickenpox is highly contagious and can cause serious complications — including pneumonia, encephalitis, and even death in high-risk individuals.
- Vaccination is the safest and most effective prevention — we carry two licensed vaccines: VARIVAX® and PROQUAD®.
- VARIVAX protects against chickenpox only, suitable for anyone aged 12 months and older — including adults and seniors.
- PROQUAD is a 4-in-1 MMRV vaccine, suitable only for children 12 months through 12 years — fewer injections, combined protection.
- We stock VARIVAX for same-day appointments — PROQUAD requires pre-payment and special ordering (3–5 working days).
📋 Summary:
Chickenpox is a common but potentially serious disease. We provide two high-quality, MSD-manufactured vaccines — VARIVAX (single-antigen) and PROQUAD (MMRV combination). Both are safe and effective. The right choice depends on age, preference for combined protection, and urgency. Speak to our clinical team for personalised advice.
Chickenpox (varicella) is a highly infectious disease caused by the varicella-zoster virus. It spreads through respiratory droplets or direct contact with blister fluid. While many children recover without complications, severe cases can lead to pneumonia, encephalitis, or even death — particularly in infants, adults, and immunocompromised individuals.
Vaccination is the most reliable way to protect yourself and your family. At our clinic, we offer two licensed chickenpox vaccines manufactured by MSD. Both are highly effective, but they serve slightly different needs.
💡 Our Commitment:
We offer both VARIVAX and PROQUAD to give patients choice. Our clinical team follows the latest guidelines and Hong Kong's immunisation standards to ensure safe, effective vaccination for every age group.

About Chickenpox — Why Vaccination Matters
- Pathogen: Varicella-zoster virus (VZV)
- Transmission: Highly contagious — respiratory droplets or direct contact with blister fluid
- Incubation: 2–3 weeks
- Complications: Pneumonia, encephalitis, secondary bacterial infections, and death (especially in immunocompromised individuals, neonates, and adults)

Frequently Asked Questions
Q: What is the difference between VARIVAX and PROQUAD?
VARIVAX protects only against chickenpox and is suitable for anyone aged 12 months or older (no upper age limit). PROQUAD is a combined MMRV vaccine that protects against measles, mumps, rubella, and chickenpox in one shot, but it is only licensed for children 12 months through 12 years.
Q: Which vaccine should I choose for my child?
For children ages 12 months to 12 years, either option is available. PROQUAD means fewer injections (4-in-1), but has a slightly higher fever risk for the first dose in children under 4 years. VARIVAX is the only choice for children who only need chickenpox protection, or for anyone aged 13 and older. Discuss with our clinical team for personalised advice.
Q: Can adults get the chickenpox vaccine?
Yes. Adults aged 13 and older should receive VARIVAX (伏痘敏). Two doses are required, 4–8 weeks apart. PROQUAD is not licensed for adults.
Q: Are these vaccines provided by the Hong Kong government?
Partially. The government provides one free dose at 1 year (Maternal & Child Health Centres) and a second dose at Primary One for children born on or after 1 January 2013. Additional doses and all doses for older individuals are self-paid (自費) at private clinics like ours.
Q: How do I book a PROQUAD vaccination?
PROQUAD requires pre-payment and special ordering. Please contact us to initiate the process. Once payment is confirmed, we place the order, and the vaccine usually arrives within 3–5 working days. We will call you to schedule the appointment immediately upon delivery.
