R0 and vaccine coverage. How to use a COVID-19 vaccine to get to herd immunity and beat Coronavirus

The video, presented by Greg Martin, explains the concept of R0, the basic reproductive number, and its significance in understanding disease spread. It discusses how the effective reproductive number, R, changes during an outbreak and the importance of achieving herd immunity through vaccination. The video also covers how to calculate the necessary vaccine coverage to control an epidemic, using COVID-19 as an example.

Discuss the implications of a sustained R value of less than one.
