The Glinda in the book is parallel to her character in the musical Wicked, sometimes behaving in a snobby and mean fashion, whereas in The Wizard of Oz, as well as in the original Oz books, she is portrayed as kind and gentle. In the original Broadway production of the musical, she was played by Kristin Chenoweth.
There is no treatment for fowl pox. Control and prevention in chickens is accomplished by vaccination by the wing web method with a commercially available fowl pox or pigeon pox vaccine. This should be administered to all chickens at 12-16 weeks of age.
The chickenpox vaccine is given to young children in two doses, the first between 12-15 months and a booster shot between 4-6 years. Children 13 and older who've never had chickenpox or been vaccinated should get two doses at least 28 days apart. The chickenpox vaccine can be given at the same time as other vaccines. It is also available as part of the measles-mumps-rubella vaccine, in a combination shot called MMRV.
