BACKGROUND Although community-acquired bacteremia is an important cause of childhood mortality in Africa, recognition of disease burden and potential impact of bacterial vaccines is limited. METHODS Blood cultures for bacterial pathogens were conducted systematically among children <15 years of age admitted to Manhiça District Hospital, from 2001 to 2006.(More)
BACKGROUND Development of an effective malaria vaccine could greatly contribute to disease control. RTS,S/AS02A is a pre-erythrocytic vaccine candidate based on Plasmodium falciparum circumsporozoite surface antigen. We aimed to assess vaccine efficacy, immunogenicity, and safety in young African children. METHODS We did a double-blind, phase IIb,(More)
BACKGROUND The candidate malaria vaccine RTS,S/AS01 reduced episodes of both clinical and severe malaria in children 5 to 17 months of age by approximately 50% in an ongoing phase 3 trial. We studied infants 6 to 12 weeks of age recruited for the same trial. METHODS We administered RTS,S/AS01 or a comparator vaccine to 6537 infants who were 6 to 12 weeks(More)
Characterization of severe malaria cases on arrival to hospital may lead to early recognition and improved management. Minimum community based-incidence rates (MCBIRs) complement hospital data, describing the malaria burden in the community. A retrospective analysis of all admitted malaria cases to a Mozambican rural hospital between June 2003 and May 2005(More)
BACKGROUND There is an urgent need to deploy and develop new control tools that will reduce the intolerable burden of malaria. Intermittent preventive treatment in infants (IPTi) has the potential to become an effective tool for malaria control. METHODS We performed a randomized, double-blind, placebo-controlled trial of sulfadoxine-pyrimethamine (SP)(More)
OBJECTIVE To describe attitudes to the expanded programme on immunization (EPI) and intermittent preventive treatment in infants (IPTi), and perceptions of the relationship between them. In particular, whether the introduction of IPTi negatively affects community attitudes to, or use of, EPI; or, conversely, whether and if so how, the concurrent delivery of(More)
BACKGROUND Malaria remains a leading global health problem that requires the improved use of existing interventions and the accelerated development of new control methods. We aimed to assess the safety, immunogenicity, and initial efficacy of the malaria vaccine RTS,S/AS02D in infants in Africa. METHODS We did a phase I/IIb double-blind randomised trial(More)
BACKGROUND RTS,S/AS02A is a pre-erythrocytic stage malaria vaccine that provides partial protection against infection in malaria-naive adult volunteers and hyperimmune adults. A previous report showed that this vaccine reduced risk of clinical malaria, delayed time to new infection, and reduced episodes of severe malaria over 6 months in African children.(More)
OBJECTIVES To describe the prevalence, aetiology and prognostic implications of coexisting invasive bacterial disease in children admitted with severe malaria in a rural Mozambican Hospital. METHODS Retrospective study of data systematically collected from June 2003 to May 2007 in a rural Mozambican hospital, from all children younger than 5 years(More)
INTRODUCTION The reference intervals of haematological and biochemical indices currently used in Africa are derived from data collected from populations living in industrialized countries. Few studies have been performed in Africa questioning the validity of these values when applied to local African populations. OBJECTIVE To provide reference intervals(More)
