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 have directly influenced Kahn in his design. Ultimately, the Salk Institute's meaning can be interpreted as transcending function and physical place as a reflection of Western civilization's pursuit of truth through science. In 2014, the Getty Conservation Institute partnered with the Salk Institute to preserve the concrete and teak building which is, due to its coastal location, subject to the punishing rigors of a marine environment. Although the Salk Institute is not a degree-granting institution, it runs a graduate program together with the neighboring UCSD, and all Salk Institute professors receive adjunct appointments in the Division of Biological Sciences at
