Course video 34 of 100

In module 5 of the course, you will learn about vaccination, one of the most common approaches to the prevention of epidemics. We'll first put vaccination in the context of the many types of public health interventions that that can be used to prevent or treat disease. After that you will learn about the development of the first vaccine, how vaccines work to prevent infection, and the impact that vaccination has had on the prevention of disease worldwide. After that, you will learn about how vaccination can provide protection to everyone, even the unvaccinated, in the population through "herd immunity" and how we can use the structure of social networks within populations to more efficiently achieve this herd protection. Finally we'll learn about how individuals choices about whether or not to get vaccinated can lead to impacts across the whole of the population.
