Flu vaccines work by calling on the immune system to produce antibodies against the virus without actually infecting the individual with the flu. Here class members see how a virus enters cells and the body defends itself. The instructor shows scholars a number of defense mechanisms—skin, inflammation, macrophages, antibodies, etc.—and how these fight off infections. Video four in a series of 21.

• Video four in a series of 21

Pros

• Images and diagrams are engaging
