Weakened germ: The main component of the vaccine is a living virus that has been weakened.The virus was first taken from a kid with chickenpox, then planted in various tissues.As the virus reproduces in tissue culture it gradually weakens with every generation. It is harvested when ready and purified.The final product is the weak virus plus a trace of neomycin & other elements used in the production.

Vaccine: Vaccines are composed of part of a virus that causes the disease. This is a live attenuated vaccine and is composed of live virus that is changed so it cannot cause chicken pox. Other vaccines have dead virus in them but work the same way by exposing your body to small amounts of the virus in a controlled way so you are less likely to get the actual disease.
