What Is Chickenpox?

Chickenpox, also known as varicella, is a highly contagious disease that spreads through direct contact with blisters, respiratory droplets from coughing or sneezing, or by touching contaminated objects. While it primarily affects children, it can occur at any age, particularly in individuals who haven't been vaccinated. For those who are immunocompromised or unvaccinated, the illness can result in more severe complications. Once someone contracts chickenpox, they typically develop lifelong immunity. However, the virus can remain dormant in the body and may reactivate later in life, causing shingles.

What Is the Varicella (Chickenpox) Vaccine for?

The chickenpox vaccine is designed to safeguard against chickenpox, a common viral illness caused by the varicella-zoster virus (VZV). The vaccine is a live attenuated vaccine, meaning it contains a weakened form of the virus that helps stimulate the immune system to build protection without causing the disease.

healthscreening.sg offers Varivax, a varicella (chickenpox) vaccine for children and adults as per Singapore’s immunisation schedules.

Chickenpox Symptoms

Chickenpox typically begins with flu-like symptoms such as:

  • Fever
  • Fatigue
  • Loss of appetite
  • Headache
  • Red, itchy rash that evolves into fluid-filled blisters
  • Blisters usually appear in clusters and begin on the face, chest, and back, spreading to other areas
  • Blisters eventually dry out and form scabs

Symptoms can range from mild to severe, and some individuals may experience complications such as dehydration, bacterial infections of the skin, blood, and soft tissues, pneumonia, encephalitis, sepsis, or an increased risk of developing shingles later in life. These complications are more common in immunocompromised individuals or unvaccinated adults.

When to Take the Varicella (Chickenpox) Vaccine?

For Children

As per the National Childhood Immunisation Schedule (NCIS), children are recommended to receive two doses of the varicella vaccine. The first dose is given at 12 months of age, with a second dose administered at least three months later.

For Adults

For adults aged 18 and older who have not been vaccinated or previously contracted chickenpox, the Singapore National Adult Immunisation Schedule (NAIS) advises two doses spaced four to eight weeks apart.

Varicella (Chickenpox) Vaccine Route of Administration

The varicella vaccine is administered via a subcutaneous injection (under the skin). It can be given on its own or in combination with other vaccines, such as the MMR vaccine, which protects against measles, mumps, and rubella.

Varicella (Chickenpox) Dose & Schedule

The recommended dosage for the varicella vaccine is as follows:

Age Group Vaccine Dosage & Schedule
Adults 18 years and older who are unvaccinated or have not had the infection previously 2 doses: 4 to 8 weeks apart

How Long Does the Varicella (Chickenpox) Vaccine Last?

The varicella vaccine typically provides lifelong protection with two doses. If you are uncertain about your immunity status, you can consider getting an antibody test or discuss the possibility of receiving a booster shot with your doctor.

What Precautions Should I Take Before a Varicella (Chickenpox) Vaccination?

Before receiving the varicella vaccine, make sure to inform your doctor if you:

  • Have any known allergies to the vaccine or its ingredients,
  • Are currently pregnant or planning to become pregnant,
  • Are breastfeeding,
  • Are feeling unwell, especially with a fever,
  • Have a weakened immune system or are undergoing treatments that might suppress your immunity,

Varicella (Chickenpox) Side Effects

Some people may experience minor side effects such as dizziness, pain or redness at the injection site, and headaches. These reactions are usually mild and temporary, but you should seek medical advice if they persist or worsen.

Uncommon but Severe Reactions to Look Out for After Your Vaccination

In rare cases, vaccinations may trigger severe allergic reactions, such as swelling of the face or eyes, breathing difficulties, or widespread itchy rashes. Should any of these symptoms occur, immediate medical attention is required.
