when was the chicken pox vaccine first used
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]
Rabies vaccine Virtually all infections with rabies resulted in death until two French scientists, Louis Pasteur and Émile Roux, developed the first rabies vaccination in 1885. This vaccine was first used on a human on July 6, 1885, on nine-year-old Joseph Meister (1876–1940), who had been mauled by a rabid dog.[8]
