Estimating the Risk of Re-Emergence after Stopping Polio Vaccination
Live vaccination against polio has effectively prevented outbreaks in most developed countries for more than 40 years, and there remain only a few countries where outbreaks of poliomyelitis by the wild strain still threaten the community. It is expected that worldwide eradication will be eventually achieved through careful surveillance and a well-managed immunization program. The present paper ...
متن کاملModelling Risk to US Military Populations from Stopping Blanket Mandatory Polio Vaccination
Objectives Transmission of polio poses a threat to military forces when deploying to regions where such viruses are endemic. US-born soldiers generally enter service with immunity resulting from childhood immunization against polio; moreover, new recruits are routinely vaccinated with inactivated poliovirus vaccine (IPV), supplemented based upon deployment circumstances. Given residual protecti...
متن کاملWild Polio Virus re-emergence in the Mediterranean

Recent outbreaks of cases due to Wild Polio Virus (WPV) type 1 have been reported in Somalia and Yemen [1]. In the WHO African Region, Nigeria is the only polio endemic country [2]. Un...
متن کاملPersistence of vaccine-derived poliovirus following a mass vaccination campaign in Cuba: implications for stopping polio vaccination after global eradication.
BACKGROUND With substantial progress made toward polio eradication, developing the appropriate strategy for discontinuing global oral poliovirus vaccine (OPV) after global eradication becomes increasingly important. At issue is the theoretical risk of independent circulation of potentially virulent OPV-derived strains. Because Cuba uses OPV only in mass campaigns, it represents an ideal site to...
