Polio eradication. Efficacy of inactivated poliovirus vaccine in India.
Inactivated poliovirus vaccine (IPV) is efficacious against paralytic disease, but its effect on mucosal immunity is debated. We assessed the efficacy of IPV in boosting mucosal immunity. Participants received IPV, bivalent 1 and 3 oral poliovirus vaccine (bOPV), or no vaccine. A bOPV challenge was administered 4 weeks later, and excretion was assessed 3, 7, and 14 days later. Nine hundred and ...
متن کاملInactivated Polio Vaccine: Its proposed role in the final stages of polio eradication
In 2000, the island of Hispaniola, home to Haiti and the Dominican Republic, was the first place where the existence of circulating vaccine derived poliovirus (cVDPV) was demonstrated [1]. As a live product, oral polio vaccine (OPV), once excreted, could enter the environment, reassort with other enteroviruses, and produce cVDPV [2]. After the investigation of that outbreak, the first of a doze...
متن کاملPolio vaccine development in Canada: contributions to global polio eradication.
The paper briefly describes Canada's distinctive experience in the control of polio and offers some lessons for governments and health policy leaders in other jurisdictions, particularly as they consider immunization policies for the post-polio-eradication era.
متن کاملImpact of inactivated poliovirus vaccine on mucosal immunity: implications for the polio eradication endgame
The polio eradication endgame aims to bring transmission of all polioviruses to a halt. To achieve this aim, it is essential to block viral replication in individuals via induction of a robust mucosal immune response. Although it has long been recognized that inactivated poliovirus vaccine (IPV) is incapable of inducing a strong mucosal response on its own, it has recently become clear that IPV...
متن کاملCirculating Vaccine Derived Poliovirus and the polio eradication endgame
The world is now in the 24 year of the Global Polio Eradication Initiative. Halfway through that initiative in 2000, the island of Hispaniola saw an outbreak of vaccine derived poliovirus [1]. The implications of this outbreak and multiple subsequent isolations of Sabin strains that are estimated to have circulated in communities for a year or more are now causing a reconsideration of the optim...
