What is Varicella?
Chickenpox (varicella) is a highly contagious viral infection caused by the varicella-zoster virus (VZV) that spreads through the air or by contact with the rash. It commonly affects children and causes an itchy red rash that turns into fluid-filled blisters before crusting over, along with fever, fatigue, and loss of appetite. In most healthy children it is mild and clears up within about a week, but it can be more serious in adults, newborns, pregnant people, and those with weakened immune systems. After recovery, the virus remains in the body and can later reactivate as shingles, a painful rash. A safe and effective varicella vaccine is available and helps prevent infection or reduce its severity.
FAQ About Varicella (Chickenpox) Vaccine
Who needs to get the varicella vaccine?
The varicella vaccine is recommended for the following population:
- All children (routine schedule): Kids are given 2 doses—one at 12 months old and another at 4–6 years old as part of the standard immunization program
- Older children, teens, and adults who aren't immune: Anyone who has never had chickenpox or hasn't been vaccinated should get 2 doses of the vaccine
- Adults who missed childhood vaccines: The vaccine is offered to adults who were not immunized when they were younger and are still at risk (called "susceptible"). This includes those who don't have a confirmed history of chickenpox infection or proper vaccination records
Are there contraindications to the vaccine?
The varicella vaccine is a live vaccine, and should NOT be given to the following individuals due to potential for serious adverse reactions:
- Women who are pregnant
- Women of childbearing age should avoid getting pregnant for at least 1 month after receipt of varicella vaccine
- Have a severe allergy to a previous dose or vaccine components (common allergens include gelatin, and neomycin)
- Immunocompromised individuals (such as from cancer, immunosuppressive medications, or advanced HIV infection)
It's also usually delayed in people who are moderately or severely ill at the time.
Is the vaccine safe and what are the possible side effects?
The varicella vaccine is generally safe, with most side effects being mild and short-lived (1-3 days), such as soreness or redness at the injection site, a low fever, or a mild rash. Some people may develop a small chickenpox-like rash or swollen glands. Serious side effects are very rare but can include allergic reactions or, in people with weakened immune systems, more significant infection-related complications.
Is the vaccine covered by MSP or private insurance?
In British Columbia, the varicella vaccine is publicly funded and provided at no cost through the provincial immunization program for eligible children, consistent with routine childhood vaccination schedules offered by public health services.
For adults without documented immunity or those at increased risk for severe disease, vaccination may be recommended but not always covered under standard MSP benefits; eligibility for publicly funded immunization may depend on age, risk category, and specific public health recommendations. Some private insurance or extended healthcare plans may cover all or part of the cost of the vaccine.
It is recommended to check with your insurance provider to confirm whether the varicella vaccine is included in your benefits plan. You can also call us with your private insurance, and we can inform you whether it is covered by your plan.
Do I need a prescription from my doctor?
No, you do not need a prescription from your doctor to receive the vaccine. Simply book an appointment with us and our pharmacist or nurse will provide the vaccine.
For children under the age of 4, please call the clinic directly as we will need to book your child in with one of our registered nurses.
