Salk developed an inactivated poliovirus vaccine (injection) that was effective in preventing most of the complications of polio, but did not prevent the initial intestinal infection.
Later, Sabin developed an oral vaccine based on mutant strains of polio virus that seemed to stimulate antibody production.
