Jonas Salk vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955. The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years. Salk's inactivated polio vaccine was the first vaccine for the disease;
Salk Institute for Biological Studies becoming greener. The Salk Institute's open environment replete with empty space is symbolic of an open environment for creation, the symmetry stands for scientific precision, and submerging crevasses allow warm, natural light to enter the buildings like the intellectual light that leads to discovery. The contrast between balance and dynamic space manifests a pluralistic invitation for scientific study in structures developed to accommodate their respective functions as parts of a research facility. Although modern in appearance, it is essentially an isolated compound for individual and collaborative study, not unlike monasteries as sanctuaries for religious discovery, and they are thought to
