Summary

The Global Polio Eradication Initiative is about to roll out a brand-new vaccine that just might overcome one of the biggest obstacles to polio eradication: out-of-control outbreaks caused by mutant polio strains derived from the vaccine itself. The new vaccine, a modern, stabilized version of Albert Sabin's oral polio vaccine, is so urgently needed that the Bill & Melinda Gates Foundation has paid for nearly 200 million doses to be produced by an Indonesian manufacturer even before clinical trials are complete. The World Health Organization is ready to grant an emergency use listing, a new approval mechanism never before used for a vaccine, as soon as Indonesia's regulatory authority gives the product the nod. The first drops could be delivered in several countries by the end of the year.
