Polio vaccine in several other African nations without necessary information, which epidemiologists believe is due to refusals by certain local populations to allow their children to receive the polio vaccine. The Salk vaccine, IPV, is based on three wild, virulent reference strains, Mahoney (type 1 poliovirus), MEF-1 (type 2 poliovirus), and Saukett (type 3 poliovirus), grown in a type of monkey kidney tissue culture (Vero cell line), which are then inactivated with formalin. The injected Salk vaccine confers IgG-mediated immunity in the bloodstream, which prevents polio infection from progressing to viremia and protects the motor neurons, thus eliminating the risk of bulbar
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
