BACKGROUND As 1 of 3 remaining poliovirus-endemic countries, Nigeria has become key to the global polio eradication effort. We evaluated supplemental immunization activities, including team performance, communications/mobilization activities, and vaccine acceptance, in 3 high-risk states. METHODS We used structured survey and observation instruments, document review, and stakeholder interview...
Paralytic polio once afflicted almost half a million children each year. The attenuated oral polio vaccine (OPV) has enabled world-wide vaccination efforts, which resulted in nearly complete control of the disease. However, poliovirus eradication is hampered globally by epidemics of vaccine-derived polio. Here, we describe a combined theoretical and experimental strategy that describes the mole...
Integrated disease control initiatives: polio eradication and neonatal tetanus elimination in Egypt.
Accelerated disease control initiatives, such as polio eradication by the year 2000, may substantially benefit public health programs in general. In Egypt, the control of other vaccine-preventable diseases, most noticeably neonatal tetanus (NT), has been facilitated by the polio eradication initiative. Linking NT reporting with the acute flaccid paralysis (AFP) surveillance system, which had be...
The data show the percentage of children ‘fully immunised’ at 12 months, 24 months and 60 months, for 3-month birth cohorts of children assessed at the stated ages between 1 January and 31 March 2014 using ACIR data as at 30 June 2014. ‘Fully immunised’ refers to vaccines on the National Immunisation Program Schedule, but excludes rotavirus, varicella, and meningococcal C conjugate vaccines. ‘F...
Worldwide efforts to eradicate polio caused a tipping point in polio vaccination strategies. A switch from the oral polio vaccine, which can cause circulating and virulent vaccine derived polioviruses, to inactivated polio vaccines (IPV) is scheduled. Moreover, a manufacturing process, using attenuated virus strains instead of wild-type polioviruses, is demanded to enhance worldwide production ...
Since the launch of the Global Polio Eradication Initiative (GPEI) in 1988 the global incidence of poliomyelitis has fallen by nearly 99 %. From a situation where wild type poliovirus was endemic in 125 countries across five continents, transmission is now limited to regions of just three countries - Pakistan, Afghanistan and Nigeria. A sharp increase in Pakistan's poliomyelitis cases in 2014 p...
Global incidence of poliomyelitis has reduced by more than 99% since the Global Polio Eradication Initiative was launched in 1988 [1]. In par with the global trend, Sri Lanka has achieved great success with no reported cases since 1993, but still is not declared as a country which has eradicated polio due to prevalence of polioyomyelitis in neighbouring countries [2]. Countries which have eradi...
15 deceMBer 2009 | KABul A new vaccine against polio will be used for the first time today in polio immunization campaigns in Afghanistan. The bivalent oral polio vaccine (bOPV), recommended by the Advisory Committee on Poliomyelitis Eradication, the global technical advisory body of the Global Polio Eradication Initiative as a critical tool to eradicate polio, can provide the optimal concurren...
BACKGROUND Cases of paralysis caused by poliovirus have decreased by >99% since the 1988 World Health Assembly's resolution to eradicate polio. The World Health Organization identified environmental surveillance (ES) of poliovirus in the poliomyelitis eradication strategic plan as an activity that can complement acute flaccid paralysis (AFP) surveillance. This article summarizes key public heal...
