What does the varicella vaccine protect against?

The varicella vaccine is specifically designed to protect against chickenpox, which is caused by the varicella-zoster virus, and shingles, a reactivation of the same virus later in life. Both conditions manifest due to the initial infection with the virus, and vaccination helps to prevent their occurrence. Chickenpox is characterized by an itchy rash and flu-like symptoms, while shingles can cause painful rashes and neurological complications. The vaccine's efficacy in reducing the incidence of both diseases underscores its importance in public health and individual health management. Understanding the specific diseases that the varicella vaccine targets is crucial for recognizing its role in immunization schedules and preventive healthcare.
