We work to spread reliable information about polio, its risks, and the lifesaving power of vaccination. Our goal is to help parents protect their children and support communities in becoming polio-free.
Polio is a highly contagious disease that can cause lifelong paralysis. Vaccination is safe, effective, and the only way to keep children healthy. Join us in the fight against polio — vaccinate today to secure a polio-free future.
Polio (poliomyelitis) is a highly infectious disease caused by the poliovirus. It mainly affects children under 5, but anyone not vaccinated is at risk..
Most people (about 70%) infected with the poliovirus have no symptoms or only mild, flu-like symptoms (fever, headache, fatigue, nausea, stiff neck, and pain in limbs) that last for a few days..
In rare cases (about 1 in 200 people), the virus attacks the nervous system and can lead to irreversible paralysis (usually in the legs). If breathing muscles are paralyzed, it can be fatal (5-10% of paralytic cases).
The virus is extremely contagious and is primarily spread through the fecal-oral route. This means contact with the stool of an infected person—often through contaminated hands, food, or water—enters another person's mouth. It can also spread less commonly through respiratory droplets from a sneeze or cough
Salk's refusal to patent the vaccine meant that it could be manufactured and distributed quickly and cheaply worldwide, maximizing its public health impact and saving countless lives. This statement perfectly captured his view of the work as a gift to humanity.
Dr. Koprowski developed the very first live, attenuated (weakened) poliovirus vaccine in the late 1940s and early 1950s—even before Sabin and Salk published their major findings—and was the first to test it on humans. His initial work was met with skepticism, but he pushed forward with large-scale trials, including one that immunized 9 million children in Poland.
