Answer: Poliomyelitis as two vaccines: Jonas Salk developed the first in 1952 and used first in 1955. This vaccine used an inactive virus. Albert Sabin developed an attenuated vaccine which was available in 1962. The Salk vaccine was given by injection and the Sabin by mouth.
Answer: Salk was hailed as a "miracle worker", and the day "almost became a national holiday." His sole focus had been to develop a safe and effective vaccine as rapidly as possible, with no interest in personal profit. When he was asked in a televised interview who owned the patent to the vaccine, Salk replied: "There is no patent. Could you patent the sun?"
