Harry Weaver (neuroscience) died at his home in San Clemente, California, age 68. The polio vaccine was discovered and developed by Jonas Salk between 1952 and 1955. Weaver, acting as the Director of Research at the National Foundation for Infantile Paralysis, now known as the March of Dimes,from 1946 to 1953, supported Salk's work with a sense of urgency for the development of the Polio vaccine. Weaver's urgency for developing a vaccine as quickly as possible was somewhat counter to the development of the Oral polio vaccine by Albert Sabin between 1954 and 1961. However, his support of Salk's vaccine was considered to
Influenza vaccine sera (chiefly against what we now call "Hemophilus influenzae"—a name derived from the fact that it was originally considered the etiological agent—and several types of pneumococci). Only one therapeutic measure, transfusing blood from recovered patients to new victims, showed any hint of success." In 1931, viral growth in embryonated hens' eggs was reported by Ernest William Goodpasture and colleagues at Vanderbilt University. The work was extended to growth of influenza virus by several workers, including Thomas Francis, Jonas Salk, Wilson Smith and Macfarlane Burnet, leading to the first experimental influenza vaccines. In the 1940s, the US military developed the first
