POST 01083E : POLIO ERADICATION 24 April 2007 ____________________________________ Sending two articles through Child Survival Update recently, Robert Davis (mailto:[email protected]) wrote : "The costs of eradicating poliomyelitis from the remaining infected countries, while high in the short term, are much lower than the long term costs of trying to control infections without eradication. And a recently developed monovalent vaccine is almost three times more effective against type 1 poliomyelitis than an existing trivalent vaccine. These are the findings of two articles published online and in an upcoming issue of The Lancet. In the first, "Eradication versus control for poliomyelitis: an economic analysis", Professor Kimberly Thompson and Dr Radboud Duintjer Tebbens of the Harvard School of Public Health, Boston, USA used a dynamic modelling technique based on current wild poliovirus endemic areas of India. The results show the importance of maintaining and increasing the immunisation intensity to complete eradication. They find that even small decreases in this intensity could lead to large outbreaks — and state that more short term funds are needed than are currently being spent.The authors conclude: "Worldwide eradication of polioviruses is likely to yield substantial health and financial benefits, provided we finish the job."? You can view this article at : http://www.technet21.org/pdf_file/PolEradicEconAnalysis.pdf "In the second paper, Dr Nicholas Grassly of the Department of Infectious Disease Epidemiology, Imperial College, London, UK and Dr Bruce Aylward, of the World Health Organisation, Switzerland and colleagues did a study of the efficacy of the monovalent oral type 1 poliovirus vaccine (mOPV1)". This other article is available from : http://www.technet21.org/pdf_file/OPV1Efficacy.pdf The situation in Nigeria concerning polio eradication has been presented and discussed in TechNet a number of times. We thus add a third article "What Led to the Nigerian Boycott of the Polio Vaccination Campaign?" by Ayodele Samuel Jegede, published this last 20 March on the Public Library of Science website. The author is senior lecturer at the Department of Sociology at the University of Ibadan in Nigeria. His article is an interesting analysis written while a Fogarty Shcolar at the University of Toronto.
