Learn the science behind the fascinating microscopic world of cellular life, viruses, and the immune system, in this online course from Tel Aviv University.

On a scale too small for our eyes to see, constant warfare rages.

With sophisticated tactics and complex biological machinery, viruses and pathogens attempt to hijack human cells, while our immune system fights back with equal ingenuity.

This online course on viruses is offered through edX and produced by Tel Aviv University, where instructor Jonathan Gershoni is Professor of Cell Research and Immunology.

Gershoni narrates a detailed yet entertaining journey through the world of viral disease, covering the basic biochemistry of cellular life, viruses, and how they cause disease; our immune system's defenses; and the enhancing effect of vaccinations.
