when did the chicken pox vaccine become available in the united states
Varicella vaccine The chickenpox vaccine first became commercially available in 1984.[2] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[5] In the United States it costs between 100 and 200 USD.[6]
Chickenpox Why the term was used is not clear but it may be due to it being a relatively mild disease.[14] It has been said to be derived from chickpeas, based on resemblance of the vesicles to chickpeas,[14][71][72] or to come from the rash resembling chicken pecks.[72] Other suggestions include the designation chicken for a child (i.e., literally 'child pox'), a corruption of itching-pox,[71][73] or the idea that the disease may have originated in chickens.[74] Samuel Johnson explained the designation as "from its being of no very great danger".[75]
