What the trial is, and whether it could suit you
Malaria caused by Plasmodium falciparum continues to be a global problem with devastating consequences. A greater understanding of the immunologic and parasitologic factors associated with infection and disease is badly needed; and will accelerate the development of highly protective vaccines for both mothers and children. Pregnancy malaria is associated with low birth weight, maternal anemia, and gestational hypertension, and both inflammation and the fetal response to infection may contribute to these poor outcomes. Childhood malaria is a major cause of mortality, and we have found that its risk is related to in utero exposure to pregnancy malaria, as well as other host factors like iron status and constitutive cytokine levels. Pregnancy malaria is caused by a distinct parasite binding phenotype, and as our primary hypothesis in this study we speculate that severe childhood malaria par

* INCLUSION CRITERIA:
A study participant must satisfy the following criteria to be or have been enrolled in this study:

2. Children who previously participated in the 1st cohort of "pregnant women and their newborn infants", OR
3. Children aged 3 years or less, who are residents of the district of Ouelessebougou for at least one year at the time of enrollment (cohort completed clinical follow up; sample and data analysis ongoing), OR
4. Febrile hospitalized children (aged 0-10 years), including those with positive and negative blood smears for P. falciparum in Ouelessebougou or the pediatric service of Gabriel Toure Hospital in Bamako. Febrile non-hospitalized children (aged 0-10 years) with non-severe malaria will be recruited at outpatient clinics in Ouelessebougou district health hospital and nearby facilities, with no chronic or serious illness.
5. Pregnant women aged 15-25 in Ouelessebougou district health centers or maternity unit of Gabriel Toure Hospital in Bamako and for a case-control study of pregnancy malaria and preeclampsia. Cases include women with signs/symptoms of preeclampsia. Control pregnant women without signs/symptoms of preeclampsia will be recruited sequentially after identification of individual cases, matched for parity, age (+/-2 years) and pregnancy trimester.(cohort completed clinical follow up; sample and data analysis ongoing)
6. The study participant or parent/guardian understands the study and gives informed consent for participation of themselves and/or their child, and agrees to have samples stored.
EXCLUSION CRITERIA:
A participant will be excluded from the study if any one or more of the following criteria are met:
1. Chronic, debilitating illness, other than malaria, determined by history and physical examination of mother or study participant.
2. Conditions that in the judgment of the investigator could increase the risk to the volunteer.
3. History of previous participation in a malaria vaccine trial.
