What Is the Varicella Vaccine for?
The varicella vaccine helps protect against chickenpox, an infection caused by the varicella-zoster virus (VZV). The vaccine uses a live but weakened form of the virus (live attenuated vaccine), so your immune system can build protection against chickenpox without you getting the illness.
What Is Chickenpox?
Chickenpox, medically termed varicella, is a viral infection that spreads easily through
respiratory droplets, direct contact with the rash, or contaminated surfaces.
Although it most commonly affects children, unvaccinated individuals of any age can contract it.
People with weakened immune systems or without prior immunity are more likely to experience
complications.
Following recovery, most individuals develop long-term immunity. However, the virus can stay dormant
in the body and potentially reactivate years later, leading to shingles.
Symptoms of Chickenpox
Initial symptoms of chickenpox are similar to those of the flu and may include:
- Fever
- Tiredness
- Poor appetite
- Headache
- A red, itchy rash that progresses into fluid-filled blisters
These blisters generally emerge on the face, torso, and back before spreading. Over time, the blisters dry
up and scab over.
While many cases are mild, chickenpox can lead to complications such as skin infections, pneumonia,
encephalitis, or sepsis. Individuals with compromised immune function or who are not vaccinated face a
higher risk of such complications.
Varicella Vaccine Dose & Schedule
Under the National Adult
Immunisation Schedule (NAIS), adults aged 18 and above who have not been vaccinated or
previously infected with chickenpox are advised to receive two doses of the varicella
vaccine.
These doses should be administered four to eight weeks
apart.
How Long Does the Varicella Vaccine Last?
With two doses, the vaccine generally provides long-lasting, often lifelong protection. If you're unsure about your immunity, a blood test can check for varicella antibodies. Your doctor may recommend a booster in specific cases.
Vaccine Route of Administration
The varicella vaccine is administered through a subcutaneous injection (beneath the skin). It may be given on its own or in combination with other vaccines, such as the MMR (measles, mumps, rubella) vaccine.
What Precautions Should I Take Before a Varicella Vaccination?
Before receiving the vaccine, inform your doctor if you:
- Are allergic to any part of the vaccine
-
Are pregnant or planning to conceive
- If planning to conceive — Avoid pregnancy for at least 1 month after receiving the vaccine.
- If already pregnant — Postpone vaccination until after childbirth.
- Are breastfeeding
- Are currently unwell, especially with fever
- Have a weakened immune system or are on immunosuppressive treatments
- Recently received any other vaccine
- Have had a recent blood transfusion
If you are unsure, consult your doctor to determine whether the varicella vaccine is suitable for you.
Potential Varicella Vaccine Side Effects
Most side effects are mild and temporary. These may include:
- Redness, pain, or swelling at the injection site
- Headache
- Light-headedness
If symptoms persist or worsen, it is advisable to seek medical advice.
Rare But Serious Reactions to Watch For
Although uncommon, some individuals may experience severe allergic responses. Symptoms to look out for include:
- Swelling of the face or eyes
- Difficulty breathing
- Generalised itchy rash
Seek immediate medical attention if any of these signs occur after vaccination.
