Where did the US get the chickenpox vaccine from?
The vaccine virus was developed from virus isolated by Michiaki Takahashi from vesicular fluid from an otherwise healthy child with varicella disease. Varicella vaccine was licensed for general use in Japan and Korea in 1988, and in the United States in 1995 for persons age 12 months or older.
I was aware of the Chickenpox vaccine starting in 1989. Recall that previously family money was used to pay their pediatrician to immunize their children.
