World Online Ranking of Best Immunology Scientists - 2026 Report
Co-Founder and Chief Data Scientist
On May 25, 2026, Research.com released the fifth edition of its annual ranking of the world’s leading immunology scientists. This report highlights researchers whose academic work has advanced immunology, clinical applications, and related scientific fields.
One objective of this report is to help students, universities, healthcare organizations, and research institutions identify experts working across different areas of immunology. The ranking also offers a clearer view of each scientist’s research output, making it easier to identify potential collaborators, advisors, and contributors to future scientific projects.
For the 2026 edition, our research team inspected over 4,900 scientist profiles collected from OpenAlex, CrossRef, and other bibliometric data sources. Each profile was reviewed based on publication records, citation performance, and overall contribution to immunology research.
To qualify for inclusion in the ranking, researchers whose primary publication field is immunology must achieve a minimum D-index of 40. Final placement is determined using a combination of D-index score, the impact and relevance of published research, and distinctions such as awards, recognitions, and scientific achievements.
Recent advances shaping immunology research
Advances in molecular biology and single-cell analysis have enabled mapping of these processes in far greater detail, helping explain how the body controls viral infections and how immune tolerance is maintained in sensitive systems like the gut.
One major development in 2025 was the discovery of new mechanisms for immune system coordination and viral defense. Researchers from Monash University identified a protein called CD44 that acts as an immune “traffic controller,” helping regulate how immune cells communicate and move throughout the body. The study also found that certain viruses can interfere with this process, weakening immune responses, providing new insight into how infections disrupt immune regulation.
Another important breakthrough shows that gut immunity depends on a highly organized network of antigen-presenting cells (APCs) that “sort” signals from food and microbes. Rather than functioning as a single, uniform system, these APCs exist in multiple specialized subtypes that either activate immune defense or promote tolerance, depending on the context of the exposure.
Single-cell transcriptomic studies have revealed that this diversity allows the gut immune system to make more precise decisions, calming responses to harmless food while still reacting strongly to harmful pathogens.
The key findings for the 5th edition of the best immunology scientists ranking
- Researchers affiliated with institutions in the United States dominate the ranking, representing the largest share of scientists in the dataset.
- The U.S. National Institutes of Health is the most represented institution with 36 scientists, followed by Harvard University with 31 and the University of California, San Francisco with 23.
- Shizuo Akira of Osaka University leads the world with a Discipline H-index of 309, while Richard A. Flavell of Yale University leads North America with 279, and Alberto Mantovani of Humanitas University leads Europe with 224.
- Scientists in the top 1% demonstrate substantially higher research impact, with an average Discipline H-index of 237.3 compared to 115.78 across the full top 1000 ranking.
- The same top 1% group also averages 247,523.8 citations and 1,199.7 publications, significantly exceeding the overall averages of 58,438.63 citations and 497.73 publications across all ranked scientists.

WORLD’S BEST IMMUNOLOGY SCIENTISTS RANKING
Countries with the highest number of leading immunology scientists
The United States continues to lead the global immunology ranking, with 524 scientists included in the 2026 top 1000 list. While this is lower than last year’s total of 540 scientists, the country still accounts for more than half of all ranked researchers. The United Kingdom remains in second place with 90 scientists, up from 87 in the previous edition, while Germany ranks third with 62 scientists, slightly down from 65 last year.
The Netherlands recorded 38 scientists this year, compared to 35 previously, securing fourth place in the ranking. Japan and Australia each have 37 scientists in the 2026 list. Japan increased from 34 scientists in the prior ranking, while Australia rose from 32 researchers.
Italy follows closely with 36 scientists, while France recorded 32 scientists, down from 37 in the earlier edition. Switzerland remains among the top-performing countries, with 24 scientists, followed by Sweden with 19 researchers.
Please note that the country associated with a scientist is based on the affiliated research institution according to MAG, not on their actual nationality.
Institutions with the highest number of leading scientists
The National Institutes of Health remains the most represented institution in the 2026 immunology ranking, with 36 scientists included in the global top 1000. Although this is lower than the previous year’s total of 41 scientists, NIH continues to lead all institutions in overall representation. Harvard University ranks second with 31 scientists, down from 37 in the earlier edition.
The University of California, San Francisco moved into third place with 23 scientists, followed by the University of Oxford with 21 researchers. The National Institute of Allergy and Infectious Diseases recorded 20 scientists this year, compared to 24 in the previous ranking. Stanford University follows closely with 19 scientists included in the list.
Several institutions recorded strong representation in the 2026 ranking, including the University of Pennsylvania with 15 scientists, Imperial College London with 14, and Washington University in St. Louis, Karolinska Institute, and the University of Washington with 13 scientists each. Yale University and the Icahn School of Medicine at Mount Sinai each had 12 scientists, while the University of Michigan–Ann Arbor and the University of Pittsburgh each had 11.
Most of the top-ranked institutions are based in the United States, reflecting the country’s strong concentration of immunology research centers, medical schools, and federally funded research organizations. Government-supported institutions such as NIH and NIAID also remain among the highest-performing organizations in the field.
The growing influence of online universities in immunology research
Online universities are becoming increasingly important in scientific education and research, particularly in fields such as immunology that rely heavily on global collaboration and digital data sharing. By offering flexible learning models, they are expanding access to advanced biomedical training for students and healthcare professionals across different regions, including areas with limited laboratory infrastructure.
A 2025 study published in BMC Medical Education found that virtual simulation experiments (VSEs) significantly improve student learning outcomes and engagement compared with traditional instruction. These simulations let students practice lab work on a computer, such as how to identify and study disease-causing bacteria, without needing to be in a physical laboratory.
The study showed that students who used these virtual labs scored higher on post-training tests and understood the lessons more clearly than those who used only standard teaching methods. It also found that students were more engaged and motivated because they could actively “do” experiments in a safe, guided digital environment.
These tools are increasingly integrated into programs offered by online universities, where virtual laboratories and simulation software enable students to perform experimental workflows without continuous access to physical lab facilities. This shift is making immunology training more scalable and accessible, especially for learners in remote or resource-limited settings.
