Varicella vaccine for adults: key points

Some adults have no clear record of vaccination or previous [Chickenpox](/conditions/chickenpox/). Others may have work, travel, household or health circumstances that make immunity especially relevant. The vaccine is a [Live Attenuated Vaccine](/materials/live-attenuated-vaccine/), so it is not suitable for everyone. A clinician reviews your record, medicines, immune function and pregnancy plans rather than deciding from age alone. Vaccination lowers the chance of chickenpox, but it does not treat an active infection.

Bring any childhood or workplace vaccination records and describe whether you remember having chickenpox. Tell the clinician about immune-suppressing medicines, severe allergies, recent illness and plans for pregnancy. Ask how many visits are needed and how to manage contact with someone who is vulnerable while your plan is being completed. The [Chickenpox Vaccination](/treatments/preventive-care-and-vaccination/chickenpox-vaccination/) information can help you prepare, but the clinic should confirm the schedule for you.

Seek urgent help after vaccination for facial or throat swelling, difficulty breathing, collapse or widespread hives. Contact a clinician quickly if you develop a severe illness, a concerning rash, or a high fever, especially with a weakened immune system. If you have been exposed to chickenpox and are pregnant or immunocompromised, call a healthcare service promptly for tailored advice rather than waiting for symptoms.

Ask whether your history is enough to show immunity, whether a blood test would clarify your record, which medicines need review, and how vaccination relates to pregnancy or planned immune treatment. Ask what to do after a chickenpox exposure.
