Varicella vaccine schedule: what to know

A schedule may involve more than one dose, with an interval chosen so the immune response can develop appropriately. The exact timing can differ for children, adolescents, adults, people preparing for travel, and those with particular medical conditions. A documented previous dose is useful; an uncertain memory of vaccination or chickenpox may require a record check and clinician assessment. Varicella vaccine is live attenuated.

Gather immunisation records and tell the clinician about pregnancy, immune-system conditions, regular medicines, allergies, and recent illness. Do not restart a schedule on your own after a delayed appointment; ask the service how to continue. Keep the next appointment information with the record. See [Chickenpox Vaccination](/treatments/preventive-care-and-vaccination/chickenpox-vaccination/) for related guidance and [Live Attenuated Vaccine](/materials/live-attenuated-vaccine/).

Ask for medical advice before a scheduled dose if pregnancy is possible, immunity is weakened, immune-suppressing treatment has started, or a serious reaction followed an earlier vaccine. Urgent care is needed for breathing problems, throat or facial swelling, fainting, or severe deterioration after vaccination. If fever and a blistering rash suggest [Chickenpox](/conditions/chickenpox/), contact a clinician for advice about infection control and treatment.

Ask how many doses your record shows, what interval applies to your situation, what happens if an appointment is late, and whether another vaccine or medicine affects the plan. Ask which reactions are expected and when to report them.
