A RT-PCR method for selective amplification and phenotypic characterization of all three serotypes of Sabin-related polioviruses from viral mixtures

Memorias do Instituto Oswaldo Cruz, 2012
Outbreaks caused by vaccine-derived polioviruses are challenging the final eradication of paralytic poliomyelitis. Therefore, the surveillance of the acute flaccid paralysis cases based on poliovirus isolation and characterization remains an essential ...

Evolution of type 2 vaccine derived poliovirus lineages. Evidence for codon-specific positive selection at three distinct locations on capsid wall. [PDF]

PLoS ONE, 2013
Partial sequences of 110 type 2 poliovirus strains isolated from sewage in Slovakia in 2003-2005, and most probably originating from a single dose of oral poliovirus vaccine, were subjected to a detailed genetic analysis.

Quantity of Vaccine Poliovirus Shed Determines the Titer of the Serum Neutralizing Antibody Response in Indian Children Who Received Oral Vaccine [PDF]

, 2017
Replication of oral poliovirus vaccine (OPV) in the intestine (ie, vaccine take) is associated with seroconversion and protection against poliomyelitis.

Are there functional consequences of a reduction in selenium intake in UK subjects? [PDF]

, 2004
Dietary Se levels in the UK have fallen over the last 20 years and recent surveys indicate that average Se intakes are 30-40 microg/d, which is well below the current UK reference nutrient intake for adult men (75 microg/d) or women (60 microg/d ...

Trends and measurement of HIV prevalence in northern Malawi.

, 2003
BACKGROUND: Most data on HIV prevalence in Malawi come from antenatal clinic (ANC) surveillance and are, therefore, subject to bias. OBJECTIVES: HIV prevalence and risk factors were measured using population-based data to assess the accuracy of ANC ...

Serological survey on immunity status against polioviruses in children and adolescents living in a border region, Apulia (Southern Italy) [PDF]

, 2008
BACKGROUND: In 1988 the World Health Assembly adopted the goal to eradicate poliomyelitis by routine immunization using Oral Polio Vaccine (OPV). On 21 June 2002 the WHO European Region was declared polio-free.

Factors Affecting Immune Reconstitution Post‐Allogeneic HSCT in Children: The Case for an Individualized Approach to Vaccination

European Journal of Haematology, Volume 116, Issue 4, Page 336-349, April 2026.
ABSTRACT Allogeneic hematopoietic stem cell transplantation (HSCT) is increasingly used to treat malignant and non‐malignant diseases. Following allogeneic HSCT, patients are particularly vulnerable to vaccine‐preventable diseases (VPD) because conditioning depletes immune cells, including memory cells.

Poliovirus vaccination during the endgame: insights from integrated modeling

Expert Review of Vaccines, 2017
Introduction: Managing the polio endgame requires access to sufficient quantities of poliovirus vaccines. After oral poliovirus vaccine (OPV) cessation, outbreaks may occur that require outbreak response using monovalent OPV (mOPV) and/or inactivated ...
