Brief Summary

Background: Malaria is a serious infection caused by a parasite. People get malaria when an infected mosquito bites them. Malaria can cause major health and social problems in places were malaria is common, such as Africa but can also affect travelers who have never been exposed to malaria. Researchers at the NIH want to find a safe and effective malaria vaccine, antimalarial drugs, or prevention regimen. To do this, healthy volunteers are recruited under a general screening study in order to see if are qualified to join a future malaria study. Objective: To screen healthy volunteers to see if they are eligible to join investigational malaria studies. The studies will be trials of investigational antimalarial drugs, malaria vaccines, or prevention regimens. They may also involve controlled human malaria infection trials. Eligibility: Healthy people ages 18 50 Design: Participants will first be prescreened by phone. Participants will be screened with: Medical history Physical exam Blood and urine tests Participants may go more than 1 year without joining a clinical trial. If this happens, they may be re-contacted to see if they still want to be part of this screening protocol. Those who still want to participate and have had relevant medical changes will be rescreened.

Study Population

healthy volunteers in the Washington, DC region

You may qualify if:

  • All of the following criteria must be fulfilled for a subject to participate in this trial:
  • Age \>= 18 and \<= 50 years.
  • In good general health and without clinically significant medical history
  • Reliable access to the clinical trial center and available in the area for more than 1 year
  • Females of childbearing potential must be willing to undergo periodic pregnancy testing and use reliable contraception per protocol when enrolled into LMIV clinical trials (protocol-specific requirements)

You may not qualify if:

  • A subject will be excluded from participating in this trial if any one of the following criteria is fulfilled:
  • Pregnant, breastfeeding, or planned pregnancy in the upcoming year.
  • Hemoglobin, white blood cell (WBC), platelets, alanine transaminase (ALT), and creatinine (Cr) outside of local lab normal range (subjects may be included at the investigator's discretion for "not clinically significant" values outside of normal range).
  • Anticipated use during the study period, or use within the following periods prior to enrollment:
  • Investigational malaria vaccine within the last five years
  • Chronic systemic immunosuppressive medications (e.g., cytotoxic medications, oral/parental corticosteroids \> 0.5 mg/kg/day prednisone or equivalent). Corticosteroid nasal spray for allergic rhinitis and topical corticosteroids for mild, uncomplicated dermatitis is allowed.
  • Recurrent receipt of blood products or immunoglobulins
  • History of:
  • Sickle cell disease
  • Splenectomy or functional asplenia
  • Systemic anaphylaxis
  • Uncontrolled psoriasis or porphyria
  • Clinically significant medical condition, physical examination findings, other clinically significant abnormal laboratory results, or past medical history that may have clinically significant implications for current health status and participation in the study in the opinion of the Investigator. A clinically significant condition or process includes but is not limited to:
  • A process that would affect the immune response, or requires medication that affects the immune response.
  • Any contraindication to repeated phlebotomy.
  • +16 more criteria

This is a screening protocol for healthy volunteers to participate in research studies conducted by Laboratory of Malaria Immunology and Vaccinology (LMIV).@@@@@@@@@@@@This screening protocol is designed to evaluate potential healthy volunteers to build a pool of volunteers who may participate in future and ongoing LMIV malaria drug, vaccine, or controlled human malaria infections (CHMI) trials. Data obtained for individual subjects will used not be used for direct research purposes on this study; therefore we will not make IPD available at this time.
