Malaria Parasite Biology, Host Immune Responses and Translational Research

Research Overview

The Idris Lab aims to address the knowledge gaps surrounding the mechanisms that underly durable immunity against malaria. Malaria persists as a significant health burden in developing countries, particularly sub-Saharan Africa where young children and pregnant women are disproportionately affected. Despite improved public health measures such as rapid diagnostics, anti-malarial drugs and insecticides, efforts to control the disease have stalled due to the emergence of resistant parasites and mosquitoes.

With over 5000 genes, Plasmodium, the causative agent of malaria, is a unicellular parasite that has a complex multi-stage life cycle and poses daunting hurdles for both the host’s immune system and effective vaccine development. Our lab is interested in revealing the vulnerabilities of this parasite and gaining an understanding of its impact on the host immune response. Such valuable insights have led to the discovery of potent monoclonal antibodies that target the pre-erythrocytic stage of the parasite’s life cycle and prevent infection [1, 3-5].

To further these discoveries, our lab will interrogate naturally exposed and vaccinated human cohorts, while simultaneously leveraging in vitro and in vivo malaria models to study host immune responses and evaluate the efficacy of potential anti-malarial biologics. Through these approaches, we can uncover novel targets that correlate to protection bringing us steps closer to unlocking the blueprint for developing more effective antibodies and vaccines.

Recognition and Media

Dr. Idris has received the prestigious NIH Director’s Award for the past three consecutive years (2021 - 2023) in recognition of her exceptional contributions to the first-in-human trial of monoclonal antibodies to prevent malaria.


Dr. Azza Idris, a native of Sudan having witnessed first-hand the devastation of malaria, now leads her own lab at the Ragon in pursuit of eradicating this disease. She is also a pediatric consultant for the Divisions of Pediatric Infectious Diseases and Global Health at Mass General Hospital for Children. Dr. Idris received her BSc in Biology from MIT before earning her dual MD/PhD degree from Mount Sinai School of Medicine. Following her residency training in pediatrics at Emory University, she dedicated 8 years to general pediatric care before pursuing subspecialty training in pediatric infectious diseases at Children’s National Medical Center. Currently, Dr. Idris holds board certifications in General Pediatrics and Pediatric Infectious Diseases.

Dr. Idris completed her post-doctoral training at the National Institutes of Health where her research focused on developing innovative human monoclonal antibodies capable of providing protection against malaria. Later appointed Head of the Malaria Unit at the Vaccine Research Center, she led efforts in the discovery, development, and evaluation of antibodies and vaccines against malaria.

At the Ragon, Dr. Idris is dedicated to cultivating a lab atmosphere that not only encourages curiosity, scientific rigor, and inclusivity but also nurtures diverse collaborations to make a lasting global health impact.
