COVID-19 immunology 101 for non-immunologists by Akiko Iwasaki, Ph.D. (English)

In just 8 minutes, learn immunology for non-immunologists with Dr. Akiko Iwasaki.

Key Concepts from Immunology 101: 

  1. Innate Immunity 101 (1:06)
  2. Adaptive Immunity 101 (3:18)
  3. Herd Immunity (7:06)


The immune system protects the host organism from invading pathogens (0:22) and is divided into the innate and adaptive immune systems (0:33). Innate immunity begins with the detection of microbial pathogens and results in the release of cytokines and interferons (1:06). Dr. Akiko explains how, in the case of SARS-CoV-2 infection, cytokine storms can cause severe disease (1:57). Adaptive immunity is the second line of defense against pathogens (3:18). Learn why and how the adaptive immune system provides long-lasting immunity (5:20). Vaccinations develop herd immunity and Dr. Akiko helps us understand how that happens (7:06).

Meet the expert:  

Dr. Akiko Iwasaki is a world renowned immunologist at Yale university where she studies immune responses to viral pathogens. Dr. Akiko’s work has important implications for the development of vaccines, like the COVID19 vaccine researchers and clinicians alike are working around the clock to make.
