This guide will break down the salary of an immunologist, explore the key factors that influence your earnings, and provide a look at the future job outlook.
What Does an Immunologist Do?
Before diving into the numbers, it's essential to understand the different career paths within immunology, as this is the single biggest factor affecting salary. Immunologists generally fall into two primary categories:
- Clinical Immunologists (Allergist-Immunologists): These are medical doctors (M.D. or D.O.) who diagnose and treat patients with diseases involving the immune system. This includes allergies, asthma, autoimmune disorders (like lupus and rheumatoid arthritis), and immunodeficiencies. They work directly with patients in hospitals, clinics, and private practices.
- Research Immunologists: These are scientists, typically with a Ph.D., who conduct laboratory research to understand the fundamental workings of the immune system. They work in academic institutions, government agencies (like the NIH or CDC), and private biotechnology or pharmaceutical companies. Their goal is to discover the underlying causes of diseases and develop new therapies.

Key Factors That Influence Salary
Your specific salary as an immunologist will be determined by a powerful combination of factors. Understanding these variables can help you maximize your earning potential throughout your career.
###
Level of Education
This is the most significant differentiator.
- M.D. or D.O.: To become a clinical immunologist, you must complete medical school, a residency in internal medicine or pediatrics, and a specialized fellowship in allergy and immunology. This extensive, patient-focused training leads directly to higher salaries associated with medical practice.
- Ph.D.: A doctorate in immunology or a related biological science is the standard for a career in research. Earnings typically start lower (often with a postdoctoral fellowship salary in the $55,000 - $70,000 range) but grow substantially as you advance to scientist or professor roles.
- M.D./Ph.D.: This dual degree positions individuals for high-level roles as physician-scientists, bridging clinical practice and research. These professionals are highly sought after to lead clinical trials and translational research programs, often commanding top-tier salaries that blend the best of both worlds.
###
Years of Experience
Experience is a universal driver of salary growth.
- Entry-Level (0-3 years): For a Ph.D., this is typically the postdoctoral fellowship stage. For an M.D., this is right after completing a fellowship and starting in a practice or academic medical center.
- Mid-Career (5-10 years): A research immunologist may have advanced to a Scientist II or Assistant/Associate Professor role. A clinical immunologist may have become a partner in a private practice or taken on leadership roles. This is where significant salary growth occurs.
- Senior-Level (15+ years): Top earners are often Principal Scientists or Directors in the pharmaceutical industry, tenured Full Professors at major universities, or senior partners in a large clinical practice. At this stage, research immunologists in the private sector can easily earn over $200,000, while clinical immunologists can exceed $350,000.
###
Geographic Location
Where you work matters. Salaries are often adjusted to reflect the local cost of living and the concentration of industry. States with major biotechnology and pharmaceutical hubs tend to offer the highest salaries for research immunologists.
According to the BLS, the top-paying states for Medical Scientists include:
1. New Jersey: $146,870
2. Massachusetts: $138,520
3. Rhode Island: $129,570
4. Connecticut: $126,890
5. California: $124,750
Major metropolitan areas like Boston/Cambridge, the San Francisco Bay Area, San Diego, and the New York/New Jersey corridor are hotbeds for immunology jobs and offer premium compensation.
###
Company Type
The sector in which you work has a massive impact on your paycheck.
