Varicella (Chickenpox) Vaccine

About

The Varicella (Chickenpox) Vaccine is a live attenuated vaccine designed to protect against varicella, a common and highly contagious childhood illness. It is recommended for all children to prevent severe cases of chickenpox, which can lead to complications such as pneumonia or encephalitis. The vaccine is typically administered in two doses: the first between 12 and 15 months of age, and a booster between 4 and 6 years old. It can be given separately or combined with the measles, mumps, and rubella (MMR) vaccine as MMRV for children up to 12 years old. The Varicella vaccine is effective in preventing severe illness and reducing the risk of chickenpox-related hospitalizations and deaths. It also provides protection against shingles, a condition caused by the reactivation of the varicella-zoster virus later in life. The vaccine is generally safe, with mild side effects such as pain or fever at the injection site. It is crucial for individuals with weakened immune systems, healthcare workers, and those in close contact with susceptible populations to be vaccinated. The vaccine has significantly reduced chickenpox cases since its introduction in 1995, making it a vital part of childhood vaccination schedules.
