VARICELLA VACCINE
The Varicella vaccine, also known as the chickenpox vaccine, is a live attenuated vaccine designed to protect against the varicella-zoster virus (VZV), which causes chickenpox. The vaccine contains a weakened form of the virus that stimulates the immune system to produce a response without causing the disease itself.
Uses:
-
Prevention of Chickenpox: The primary use of the varicella vaccine is to prevent chickenpox, a highly contagious disease characterized by an itchy rash, fever, and fatigue.
-
Herd Immunity: By vaccinating a significant portion of the population, the spread of the varicella virus can be controlled, providing indirect protection to those who are not vaccinated, such as infants, pregnant women, and immunocompromised individuals.
-
Reduction of Complications: The vaccine helps reduce the risk of severe complications associated with chickenpox, such as bacterial infections, pneumonia, encephalitis, and hospitalization.
-
Prevention of Shingles: Vaccination against varicella in childhood may also reduce the risk of developing shingles (herpes zoster) later in life, as the same virus causes both conditions.
Administration:
- The varicella vaccine is typically given in two doses.
- The first dose is recommended for children between 12 and 15 months of age.
- The second dose is usually administered between 4 and 6 years of age.
- For older children, adolescents, and adults who have not had chickenpox or the vaccine, the two doses are given at least 4 weeks apart.
Effectiveness:
- The vaccine is highly effective, with about 90% of individuals developing immunity after two doses.
- Breakthrough infections (chickenpox in vaccinated individuals) are usually mild and of shorter duration.
