OBJECTIVE To assess the effectiveness of mass vaccination in Cuba of children under 2 years of age against Haemophilus influenzae type b (Hib), the most common causative pathogen of bacterial meningitis. METHODS The availability of effective Hib conjugate vaccines led to a nationwide vaccination program in 1999 targeting all children under 2 years of age,(More)
BACKGROUND With substantial progress made toward polio eradication, developing the appropriate strategy for discontinuing global oral poliovirus vaccine (OPV) after global eradication becomes increasingly important. At issue is the theoretical risk of independent circulation of potentially virulent OPV-derived strains. Because Cuba uses OPV only in mass(More)
The vaccine against measles came into use in Cuba in 1971. During the seventies, a new early strategy for measles control was established, and it was followed by further efforts in the early eighties. Despite improvements to the control program, disease outbreaks continued to occur. In 1986, after examining the experience acquired through the control(More)
The immunogenicity of trivalent oral poliovirus vaccine (TOPV), which is less effective in tropical than in temperate areas, may potentially be improved in several ways, including increasing the number of doses. Little information is available on TOPV when more than 6 doses are given. The situation in Cuba provides a unique opportunity to relate the(More)
Free software development emerges like a quite effective proposal that improves final quality and reduces development time in certain types of software construction. For that reason, current software engineering research concentrates important efforts to analyze its peculiar properties. This paper examines some aspects of free software related to the(More)
Results suggest that malabsorption of amino acids which occurs duringEimeria nieschulzi andNippostrongylus brasiliensis infections in rats is not due to impairment by intestinal inflammation of gamma-glutamyl transpeptidase activity.
The surveillance of the circulation of the wild poliovirus is an essential element for the eradication of poliomyelitis. The Pan-American Health Organization emphasises on the etiological study of acute flaccid paralysis in order to achieve this aim. The characteristics of our program against this entity allowed to use the presence of antibodies in a sample(More)
