Tara Mangal and colleagues document the struggle to eliminate polio in northern Nigeria. However, they overlook the importance of routine immunisation to polio eradication eff orts. The investigators identified an association between the risk of contracting polio and oral polio vaccine unavailability. Systemic problems with routine immunisation distribution, supply chain, and staffi ng result i...
1 Representative of the Director-General for Polio Eradication, World Health Organization, Geneva, Switzerland (email: [email protected]). The articles in this theme issue of the Bulletin address the complex policies of polio eradication. The end of wild poliovirus transmission is not the end of the story, as certification of eradication, laboratory containment, vaccination policy, and sustainab...
BACKGROUND Although rare, adverse events may associate with anti-poliovirus vaccination thus possibly hampering global polio eradication worldwide. OBJECTIVE To design peptide-based anti-polio vaccines exempt from potential cross-reactivity risks and possibly able to reduce rare potential adverse events such as the postvaccine paralytic poliomyelitis due to the tendency of the poliovirus geno...
an interference is observed between whooping-cough antigens and salk polioc vaccine even if the two components are mixed immediately before use. the phenomenon is more evident when flulid antigens are injected. pertussis soluble antigen, which gives a good serological response in rabbits, when used alone or combined with dt, is inactivated in the presence of salk polio vacc:ne
Israel was certified as polio-free country in June 2002, along with the rest of the World Health Organization European Region. Some 11 years later, wild-type polio virus ₁ (WPV₁) was isolated initially from routine sewage samples collected between 7 and 13 April 2013 in two cities in the Southern district. WPV₁-specific analysis of samples indicated WPV₁ introduction into that area in early Feb...
BACKGROUND The final endgame strategy of global polio eradication initiative includes switching from trivalent oral poliovirus vaccines (tOPV) to bivalent oral polio vaccine (bOPV), and introduction of inactivated poliovirus vaccine (IPV). This study compares IPV with tOPV week 39 boost in Indian infants. METHODS Starting 28 March 2012, we enrolled 372 Indian infant-mother pairs from Kolkata,...
INTRODUCTION Children in Singapore receive vaccination against hepatitis B virus (HBV) at 0, 1 and 5 or 6 months of age, and vaccination against pertussis, diphtheria, tetanus, and polio at 3, 4 and 5 months of age. Parents often choose to vaccinate with the combined acellular-pertussis-inactivated polio-Hib vaccine (DTPa-IPV/Hib). We investigated whether a combined hexavalent vaccine, DTPa-HBV...
Now that the global eradication of wild poliovirus is almost within sight, planning for the post-certification era is becoming a priority issue. It is agreed that a stockpile of appropriate polio vaccines will need to be established, and a surveillance and response capacity will need to be maintained, in order to protect the world against any possible future outbreaks attributable either to the...
vaccines to prevent poliomyelitis have been available for 48 years, paralytic disease continues to occur in some areas, as reported by Kohler et al. 1 elsewhere in this issue of the International Journal of Epidemiology. Let us hope that by the 50th anniversary of the development of the first successful polio-myelitis vaccine all transmission of wild-type polioviruses will have ceased. The Worl...
