Chickenpox (Varicella) Vaccination

Chickenpox is a highly contagious infection caused by the varicella-zoster virus. It causes a blister-like rash across the body. It is common for those infected to have between 250 and 500 itchy, annoying blisters.

Those at highest risk are babies, adults and those with weakened immune systems. The best prevention is through vaccination.

The chickenpox vaccine provides the best protection against chickenpox and the varicella-zoster virus. In Canada, Passport health offers the Varivax vaccine. This provides protection against chickenpox and is approved for use in children 12 to 15 months and four to six-years-old.

Yes, the chickenpox vaccine is safe and effective. Side effects are rare and generally include sore arm or mild rash. This is common with any vaccination or injection. For additional information see the PHAC’s chickenpox vaccine safety page.

The varicella-zoster virus spreads quickly and easily through touching or breathing viral particles. Blisters are the most common source of spread.

Chickenpox can spread from someone with shingles to other who has never had the disease. This happens if a person touches or inhales droplets of the shingles blisters.

Infected persons can spread the virus for a few days before showing symptoms until blisters have scabbed. Many people will not show symptoms for anywhere from 10 to 21 days after exposure.

Symptoms of chickenpox normally last five to seven days. They will often include:

• Itchy, Fluid-Filled Blisters
• Rash (especially on face, chest and back)
• Fever
• Tiredness
• Loss of Appetite

Severe cases of chickenpox are rare, but possible. Complications can include bacterial infection, bleeding and dehydration.
