The live vaccine that is the major tool of the program evolves rapidly in vaccine recipients, can spread to their contacts to some extent and can on rare occasions cause poliomyeltis. Some of the difficulties that this implies for the eventual complete cessation of vaccination are proving to ...
GENEVA -- The World Health Organization (WHO) does not recommend oral poliovirus vaccine (OPV) for preventing COVID-19, according to its daily situation report released Wednesday. The UN body said there is no evidence that OPV, primarily used against polio, protects people against COVID-19, t...

In rare cases, the live virus in oral polio vaccine can mutate into a form capable of sparking new outbreaks. All the current vaccine-derived polio cases have been sparked by a Type 2 virus contained in the vaccine. Type 2 wild virus was eliminated years ago. ...
Poliomyelitis (polio), the much-feared crippling epidemic disease of the twentieth century, is on the verge of eradication. Before introduction of the inactivated poliovirus vaccine (IPV) in 1955 and the oral poliovirus vaccine (OPV) in 1961, polio had n
The original cre was inactivated by mutations (cremut); 3Dpol mutations HiFi (D53N) and Rec1 (K38R) reduce overall virus adaptation capacity by reducing mutation and recombination rates, respectively. (B) One-step growth analysis of nOPV2 and the current vaccine Sabin2 viruses in Vero cells...
Nathanson cites three possibilities: those are warm climates, so poliovirus doesn’t go dormant in the winter as it theoretically did in other countries; the prevalence of other enteroviruses means that the live-virus polio vaccine is not as effective because the other viru...
Vaccine technology being developed at The University of Queensland could hold the key to completely eradicating polio by removing live virus from the vaccine production process.
