Many: The salk vaccine to protect against polio became available in 1955, dramatically reducing the number of cases. Prior to the vaccine becoming available, around 20, 000 cases of polio occurred yearly in the us. The worst year was 1952; that year 57, 628 cases were reported in the us alone. By comparison, in 2011 only 650 cases were reported in the entire world! vaccines work.
