Question
My baby is due for the chickenpox vaccine this time. How long does the preventive effect of this vaccine last: long-term or just a few years?
Answer
The chickenpox vaccine is prepared from the attenuated strain of the chickenpox virus and is the only means to prevent chickenpox infection. Vaccination not only prevents chickenpox but also prevents complications caused by herpes zoster. After receiving the chickenpox vaccine, individuals can develop a more sustained immunity to the virus. The vaccine stimulates the body to produce immunity against the chickenpox virus, used for preventing chickenpox. Generally, it provides immunity for over 5 years, and some individuals may even achieve lifelong immunity.
