Dr Chris Smith: why does the vaccine wane?

From Saturday Morning, 8:20 am on 20 November 2021

Our regular commentator, Cambridge University consultant clinical virologist Dr Chris Smith joins us with the latest Covid-19 science, and to answer your questions.

This week we’ll be asking Dr Smith why the effects of the Covid-19 vaccine wane over time, when other vaccinations do not? How likely is it that another variant might sidestep the existing vaccinations? And is there any sign of this pandemic burning itself out?
