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

R0 (the basic reproductive number) tells us more than just how many people will be infected in a totally susceptible population. It can be used to calculate the how much vaccine coverage is needed to get to herd immunity. As COVID-19 continues to spread, the development of a vaccine that will be used to immunise people is being talked about. A Coronavirus vaccine is likely to give immunity for about a year.
