Vaccine details
Who should be vaccinated?
Children typically receive two chickenpox vaccine doses: the first at 12-15 months, and the second at 4-6 years (or at least 3 months after the first). The MMRV vaccine, combining protection against measles, mumps, rubella, and chickenpox, is an option for children aged 1-12 years; your doctor can advise on the best choice. Catch-up shots are available if doses are missed.
Adults not immune to chickenpox require two doses, administered approximately one month apart. Consult your doctor to ensure your family is protected.
Who should NOT be vaccinated?
Do not get the chickenpox vaccine, or wait, if you:
- Had a life-threatening allergic reaction to a previous dose or vaccine ingredient (e.g., gelatin, neomycin).
- Recently had a blood transfusion or other blood products.
- Have an illness more serious than a cold.
Tell your doctor before vaccination if you:
- Have HIV/AIDS or an immune system disorder.
- Are taking immune-suppressing medications.
- Are undergoing cancer treatment.
Special Issues
Chickenpox vaccines have reduced cases by 97%, proving to be an effective public health response.
