Overview

Viral infections are responsible for many human diseases, from common diseases like the flu to emerging infections such as Zika virus and SARS-CoV-2. Understanding how the immune system works to prevent and remove viral infections is essential for anyone working to develop or distribute vaccines that can protect against these diseases. 

Discover how the immune system functions to prevent and eliminate viral infections, including common pathogens like influenza and emerging viruses such as Zika, Ebola, and SARS-CoV-2 in this advanced HMX course. You will gain a firm understanding of the viral life cycle, focusing on how viruses infiltrate and replicate within host cells, evade the immune system, and target specific tissues in the body. By highlighting these processes, you will understand how the immune system can be harnessed to develop effective vaccines by exploring the different types of vaccines, recent advances in vaccine development (including mRNA vaccines), and the technologies that have made these advances possible. 

Learning Objectives

  • Learn the basics of how viruses can infect cells and cause disease
  • Gain an understanding of the ways that the human immune system fights off viral infections, and the methods that viruses use to evade the immune response
  • See examples of how knowledge of the immune response to viruses can inform vaccine development

Who Should Participate

Medical professionals; researchers in immunology or adjacent fields; professionals in the biotechnology or pharmaceutical industries

About the Course

HMX online courses bring complex material to life through engaging biomedical visualizations, clinical applications, and true-to-life scenarios paired with lectures from Harvard Medical School faculty and leading experts. 

Who Should Enroll

This advanced course is appropriate for medical professionals seeking in-depth knowledge of the viral life cycle and the immune response to viruses; researchers in immunology or adjacent fields who are interested in exploring the pathogenesis of different viral infections and the antiviral immune response; professionals in the biotechnology or pharmaceutical industry who are eager to understand the process of vaccine development, from laboratory research and clinical trials to full-scale manufacturing. 

Course Format

Most people can expect to spend around 15–20 hours total, but this depends on your baseline knowledge, how carefully you take notes, and how seriously you take the assessments. Lessons from the courses are released toward the beginning of the course session and remain available until the courses end, so you can work at your own pace. There is a final exam at the end of each course that can be taken at any time during the multi-week final exam period. The flexible course format makes this an ideal choice for working professionals.

This course focuses on how the immune system responds to viruses and how vaccines are designed and used to prevent viral diseases. You’ll explore viral structure and replication, immune responses, vaccine platforms, and real‑world examples such as influenza and COVID‑19.

Highlights include visual explanations of viral life cycles and immune responses, case‑based discussions of vaccine development and deployment, and exploration of current and emerging vaccine technologies. The course connects basic science to public health and clinical decision‑making.

The course is intended for clinicians, public health professionals, biomedical researchers, and health care industry staff who need a strong understanding of viral immunology and vaccine science.

This course is right for you if you work with vaccines or viral diseases in clinical practice, public health, research, or industry, or if you support communication and policy related to immunization. It is particularly valuable if you want to connect mechanistic understanding of viral immunity with real‑world vaccine development, deployment, and decision‑making.

Typical learners include physicians and advanced practice providers, epidemiologists and public health practitioners, laboratory and research scientists, and professionals from vaccine and pharmaceutical companies in roles such as medical affairs, clinical development, and policy or communications. Many have prior exposure to immunology or infectious diseases and want to deepen their vaccine‑specific expertise.

By completing this course, you’ll gain a stronger grasp of how viral pathogens interact with the immune system and how different vaccine platforms work, which can inform clinical decisions, public health planning, and vaccine development or communication strategies. The Certificate of Completion from Harvard Medical School can also highlight your training in vaccine and viral immunology to employers, collaborators, and professional audiences.

Expertise in this area usually involves advanced training in infectious diseases, immunology, virology, epidemiology, or related fields—such as an MD/DO, PhD, or MPH—with research or clinical experience focused on viral infections and vaccines. This course provides a focused, clinically and public health–oriented overview that can complement those paths, support specialization in vaccine‑related roles, and keep you current with evolving vaccine technologies and strategies.

Vaccines and Viral Immunology is a 10‑week, online, instructor‑paced course with an expected workload of about 1–2 hours per week, plus a final exam during a multi-week exam window.

Your progress throughout the course will determine your eligibility for a Certificate of Completion from Harvard Medical School. Earning a certificate requires significant effort; learners must complete all course material by the course end date in order to qualify.
