Vaccine-associated paralytic poliomyelitis in Brazil, 1989-1995.
At the present time, the only poliovirus-caused poliomyelitis cases reported in Brazil and other countries of the Americas are of vaccine etiology. It is important for epidemiological surveillance and immunization programs to evaluate the epidemiological profile of cases of vaccine-associated paralytic poliomyelitis (VAPP) in order to establish criteria for case definition and vaccination strat...
متن کاملVaccine-associated Paralytic Poliomyelitis in Immunodeficient Children, Iran, 1995–2008
To determine the prevalence of vaccine-associated paralytic poliomyelitis (VAPP) in immunodeficient infants, we reviewed all documented cases caused by immunodeficiency-associated vaccine-derived polioviruses in Iran from 1995 through 2008. Changing to an inactivated polio vaccine vaccination schedule and introduction of screening of neonates for immunodeficiencies could reduce the risk for VAP...
متن کاملVaccine-associated paralytic poliomyelitis.
In the wake of the World Health Organization’s (WHO) program to eradicate poliomyelitis globally by the end of the year 2000 (in 1997 only 5,186 cases were reported world-wide), attention has focussed on the importance of good surveillance of acute flaccid paralysis, which is essential for a country to qualify for being declared polio-free, and on the occurrence of vaccine–associated paralytic ...
متن کاملRisk of vaccine-associated paralytic poliomyelitis in Latin America, 1989-91.
A major factor influencing the success of poliomyelitis eradication in the Americas was the reliance on mass immunization campaigns with oral poliovirus vaccine (OPV). As global poliomyelitis eradication activities accelerate and campaign vaccine delivery strategies are applied elsewhere, it is critical to determine whether the risk of vaccine-associated paralytic poliomyelitis (VAPP) is altere...
متن کاملVaccine-associated paralytic poliomyelitis: a retrospective cohort study of acute flaccid paralyses in Brazil.
BACKGROUND At the present time, in Brazil and other countries in the Americas, the only cases of paralytic poliomyelitis due to poliovirus are caused by vaccine strains. The recognition of possible determinants of vaccine-associated paralytic poliomyelitis (VAPP) by public health surveillance and immunization programmes is relevant to inform the debate on criteria for case definition and vaccin...
