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.
The impact was dramatic: in 1955 there were 28,985 cases of polio in the U.S. and by 1957 that number had decreased to 5,894. Since he wanted it to be distributed freely to everyone, Dr. Jonas Salk never patented his polio vaccine.f course, that didn't stop inventor Dr. Jonas Salk from keeping busy â his last years were spent searching for a vaccine to combat AIDS.
