Polio, which struck children disproportionately, could attack the central nervous system and cause muscle deterioration, paralysis and even death. American virologist Jonas Salk, who was born 100 years today on October 28, 1914, developed the worldâs first safe and effective polio vaccine.
Dr Jonas Salk develops the first vaccine against polio â an injectable, inactivated (killed) polio vaccine (IPV). Dr Albert Sabin develops a live oral vaccine against polio (OPV), which rapidly becomes the vaccine of choice for most national immunization programmes in the world.r Jonas Salk develops the first vaccine against polio â an injectable, inactivated (killed) polio vaccine (IPV).
