The global incidence of poliomyelitis has dropped by more than 99 per cent since the governments of the world committed to eradication in 1988. One of the three serotypes of wild poliovirus has been eradicated and the remaining two serotypes are limited to just a small number of endemic regions. However, the Global Polio Eradication Initiative (GPEI) has faced a number of challenges in eradicat...

Historical records of patients with vaccine-associated paralytic poliomyelitis (VAPP) in Hungary during 1961-1981 were reviewed to assess the risk of VAPP after oral polio vaccine (OPV) administration. A confirmed VAPP case was defined as a diagnosis of paralytic poliomyelitis and residual paralysis at 60 days in a patient with an epidemiologic link to the vaccine. Archived poliovirus isolates ...

www.nexusmagazine.com NEXUS • 37 P ro-vaccinators claim eradication success with vaccines against two diseases: smallpox and poliomyelitis. The problem is that both these claims are not true, but many people believe them. In this article, I deal with outbreaks of paralytic poliomyelitis straight after mass vaccination programs in both developed and developing countries, as published in orthodox...

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...

Objective: The objective of this study was to analyze the current strategies used for eradicating wild polio viruses (WPV) and to propose some innovative strategies that may help to accelerate the progress towards polio eradication. Methods: We assessed the current strategies proposed by the World Health Organization, and the effectiveness of the current trivalent oral polio vaccine types 1, 2 ...

Why do we not, then, use inactivated polio vaccines for routine immunisation in childhood? Parents would not need to be immunised at the same time as their child; and the current inactivated polio vaccines (improved considerably compared with the earliest examples) induce reliable and lasting immunity and are safe. Moreover, in the Netherlands the vaccine has virtually eliminated the disease,9 ...

When the Expanded Programme on Immunization was established and oral poliovirus vaccine (OPV) was introduced for developing countries to use exclusively, national leaders of public health had no opportunity to make an informed choice between OPV and the inactivated poliovirus vaccine (IPV). Today, as progress is made towards the goal of global eradication of poliomyelitis attributable to wild p...

Reasons for the low coverage of immunization vary from logistic ones to those dependent on human behaviour. The study was planned to find out: (a) the immunization status of children admitted to a paediatric ward of tertiary-care hospital in Delhi, India and (b) reasons for partial immunization and non-immunization. Parents of 325 consecutively-admitted children aged 12-60 months were interview...
