MAGARINOS, Mirta et al. Antipoliomyelitic vaccination in children living in Buenos Aires City. Arch. argent. pediatr. [online]. 2010, vol.108, n.1, pp.71-74. ISSN 0325-0075.

Following the presentation of a confirmed case of paralytic polio Sabin-derived virus (VSD) in a child of 15 months we analyzed the coverage of poliomyelitis vaccination in children living in the City of Buenos Aires, in the 2006/2008 triennium. There was an improvement over the period analyzed, but values above 95% were reached only for the first dose. The proportion of inactivated vaccine (IPV) increased at the expense of live oral vaccine (OPV); in 2008, the first dose IPV coverage was 37.64% and 19.48% for the school entrance. The lack of intestinal immunity that occurs in children immunized with IPV, plus a poor coverage with OPV, allows the circulation of wild virus or VSD favoring the occurrence of paralytic poliomyelitis in unvaccinated or immunocompromised children.

Keywords : Vaccination coverage; Sabin-derived virus; Poliomyelitis vaccination; OPV; IPV.
