Re: Medical History
A good nurse that shows compassion and delivers good care is priceless! As for vaccines, two of the most important vaccine developments were the Smallpox vaccine and the Polio vaccine. Because of the Smallpox vaccine, given routinely in the U.S. until 1971, the disease was declared eradicated in 1977. The Salk polio vaccine, developed by Jonas Salk in 1952, and later the Sabin oral Polio vaccine developed in 1957, have contributed to Polio being nearly eradicated.
