The wild poliovirus appears to be nearing eradication as there were perhaps as few as 5 cases in 2021. However, the occurrence of polioviruses derived from the use of the Sabin oral vaccine has become many times greater (51 cases) than that of the wild virus, even though (or perhaps because) the oral vaccine powered the eradication of the wild virus from almost all continents. These vaccine-derived polioviruses can behave like wild viruses and cause paralysis, so they too must be eradicated to end polio once-and-for-all.
Don Napper will explain how Vaccine-Derived Polioviruses are slowing the “End Polio Now” program.
Emeritus Professor Don Napper was educated at Sydney and Cambridge Universities in molecular chemistry. He retired from Sydney University in 2003 as the Pro-Vice-Chancellor (Sciences & Technology), where he is now Professor Emeritus.
