Oxford Mathematician explains the effect of Vaccines on the COVID-19 Pandemic

University of Oxford Mathematician Dr Tom Crawford explains how the availability of vaccines affects our ability to fight the COVID-19 pandemic. Three main questions are answered using the SIR model for disease spread:

What is the condition for the pandemic to stop?

How many people do we need to vaccinate to reach this?

What happens if the vaccines aren’t 100% effective?

Watch Tom explain the ‘SIR Model for Disease Spread’ here.

Tom also looks at the effects of spatial dependence with a ‘Travelling Wave SIR Model’ here.

Finally, the effects of an ‘Incubation Time’ for the disease are investigated here.
