who created the polio vaccine

Jonas Salk is credited with creating the first widely used polio vaccine, introduced in 1955 as an inactivated (killed) polio vaccine. Later, Albert Sabin developed the oral polio vaccine, which became crucial for mass immunization campaigns worldwide.

Main creators

• The first effective, publicly introduced polio vaccine was developed by Jonas Salk, using an inactivated poliovirus and first used on a large scale in 1955.

• A few years later, Albert Sabin created a live, attenuated oral polio vaccine that was easier to administer and helped drive global vaccination programs.

Why Salk is most often named

• When people ask “who created the polio vaccine,” they usually mean Jonas Salk because his 1950s vaccine was the first to be proven safe and effective in huge clinical trials.

• His work dramatically reduced polio cases in countries that adopted the vaccine, turning him into a widely recognized medical hero.

Broader team effort

• Salk and Sabin both relied on earlier research by virologists who identified poliovirus types and developed lab methods to grow the virus, so the vaccines were the result of a broader research community.

• Global health organizations and national programs then used these vaccines in coordinated campaigns that brought the world close to eradicating polio in many regions.
