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.
