Eradication of polio
Once a global scourge, polio is now close to total elimination, with only a handful of cases reported worldwide every year. Although a vaccine has been available since the 1950s, the drive to finally wipe out the disease began in 1988 with the formation of the Global Polio Eradication Initiative (GPEI). A multi-partner initiative including the World Health Organization and US Centers for Disease Control and Prevention, the GPEI fosters collaboration between national governments, thousands of polio vaccinators, health workers and community organisers. Together they reach more than 400 million children every year in more than 40 countries with over one billion doses of polio vaccines.
