VZ-Vax (Live Attenuated Varicella Virus)

The Varicella-Zoster vaccine, commonly known as the chickenpox vaccine, is essential for preventing chickenpox. Here are some key points about this vaccine:

1. What is Chickenpox (Varicella)?
- Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV).
- It presents as an itchy, blister-like rash that starts on the chest, back, and face, and then spreads over the entire body.

2. Vaccine Basics:
- The chickenpox vaccine is also called the varicella vaccine.
- It is made from a live but weakened (attenuated) form of the varicella-zoster virus.
- The vaccine helps prevent chickenpox by stimulating the immune system to produce protective antibodies.

3. Vaccine Schedule:
- The Centers for Disease Control and Prevention (CDC) recommends two doses of the chickenpox vaccine for children, adolescents, and adults.
- Children should receive the first dose at 12 through 15 months old and the second dose at 4 through 6 years old.

4. Effectiveness:
- Two doses of the vaccine are about 90% effective at preventing chickenpox.
- Even if vaccinated individuals still get the disease, it is usually milder with fewer blisters and little or no fever.

Remember, getting vaccinated not only protects you but also helps prevent the spread of chickenpox to vulnerable populations.
