Varicella zoster virus vaccine; Varivax; Vaccine - chickenpox
Chickenpox is caused by the varicella-zoster virus (VZV). It is very common and spreads very easily. Chickenpox occurs more often in the winter and spring.
Most of the time, the infection is mild and not life-threatening. However, some people with chicken pox become seriously ill, need to be in the hospital, or even die from the disease.
The chickenpox vaccine works very well in preventing the disease. A small number of people who get the vaccine will still get chickenpox. However, they usually have a milder case than persons who did not receive the vaccine.
WHO SHOULD RECEIVE THIS VACCINE
Children should receive two doses of the traditional chickenpox vaccine.
People 13 and older who have not received the vaccine and who have not had chickenpox should get two doses, 4 to 8 weeks apart.
