The RTS,S/AS01 malaria vaccine is being introduced sub-nationally in phased pilot introductions through the EPI programmes in Malawi Ghana and Kenya. Vaccine introduction is by the respective MoH in selected areas randomly assigned to receive the vaccine at the beginning of the pilots. In the context of this programmatic activity, the Malaria Vaccine Pilot Evaluation (MVPE) registered here as observational evaluations during early vaccine introduction, include a series of 3 household surveys, and sentinel hospital and community mortality surveillance, building on routine systems. These observational evaluations will measure: 1. The programmatic feasibility of delivering a 4 dose schedule; 2. Safety in routine use, with focus on cerebral malaria and meningitis; 3. The impact of the malaria vaccine in routine use on severe malaria and all-cause mortality
Background: In high-transmission settings, up to 70% of school-aged children harbour malaria parasites which is mostly asymptomatic, thus, from an epidemiological point of view, they contribute significantly as reservoir to onward malaria transmission to others. In endemic areas, malaria accounts for around 50% of the mortality, 13-50% of all school absenteeism, and causes anaemia in approximately 85 million school-aged children of sub Saharan Africa that also impairs the cognitive development of children. Intermittent preventive treatment (IPT) of pregnant women as well as seasonal malaria chemoprevention in children under the age of five have been implemented in several sub-Saharan countries and have proven to be very effective. However, none of these IPT strategies is targeting school children. A clinical trial is being conducted to expand the IPT by testing effectiveness and safety of two antimalarial drugs Dihydroartemisinin-piperaquine (DP) and Artesunate-amodiaquine (ASAQ) in preventing malaria related morbidity in school aged children (IPTsc) living in high endemic areas. Methods: A randomized, open label, controlled trial will enrol 1602 school children aged 5-15 years, who will receive either DP or ASAQ or control (no drug ), using a "balanced block design" with the "standard of care" arm as reference. The interventional treatments are given every 4 months 3 rounds for the first year. A second non-interventional year will assess possible rebound effects. All study-arms receive bed nets, early diagnosis and care for malaria, and praziquantel and albendazole as mass treatment for helminthiasis. The primary endpoint are change from baseline in mean haemoglobin concentration at months 12 and 20 of follow-up and clinical malaria incidence from month 0 till months 12 and 20 of follow up. Adverse events will be monitored throughout the study. Mixed design methods will be used to assess the acceptability, cost-effectiveness and feasibility of this IPTsc as part of a more comprehensive school children health package. Discussion: The national school health programme (NSHP), Tanzania, combines schistosomiasis and soil transmitted helminthes (STH) control package under national schistosomiasis and STH control programme (NSSCP). Malaria intervention using IPTsc strategy may be integrated in NSHP with the same platform as NSSCP, however, there is limited systematic evidence to assess the operational feasibility of this approach. School aged children are a reachable target population in any endemic malaria setting. The suggested strategy will provide effective protection against malaria, hasten either the elimination process and/or diminish the reservoir and burden.
It has long been recognized that the positive effects of vaccination on childhood mortality cannot be solely attributed to a decline in the disease targeted by the vaccine. These so-called non-specific effects of vaccination have so far mostly been linked to mortality. However, it has been suggested that non-specific effects may also effect morbidity and nutritional status. This study aims to further explore the correlation between vaccination, susceptibility to infectious diseases (particularly malaria and bacterial infections), nutritional status and immunity. With this prospective cross sectional study among healthy individuals in rural west-Africa we aim to address several research questions at the same time. This study will assess the influence of (time-point of) vaccination on morbidity, mortality and immune status among healthy individuals in a rural sub-Saharan African setting. Secondly, to explore the prevalence of subclinical malaria, iron deficiency anemia, sickle cell anemia and thallasemia among a healthy rural sub-Saharan African population. And finally to assess normal hemocytometry values among a healthy rural sub-Saharan African population.
The objective of this study is to explore the role of fosmidomycin and piperaquine as non-artemisinin-based combination therapy for acute uncomplicated Plasmodium falciparum when administered over three days. Together, fosmidomycin and piperaquine fulfil the WHO criteria for combination therapy by meeting the three key parameters of having different modes of action and different biochemical targets while exhibiting independent blood schizonticidal activity. Like the artemisinins, fosmidomycin is fast-acting, has an excellent safety record and is active against existing drug-resistant parasites. Piperaquine has a long half life protecting fosmidomycin as a much shorter lived molecule against selection of resistant parasites and will provide post-treatment prophylaxis.
The aim of this study is to evaluate the role of azithromycin as a possible combination partner for fosmidomycin to protect it from its susceptibility to recrudescent infections when used as monotherapy for acute Plasmodium falciparum malaria while retaining its excellent safety profile.
