Vaccines have arguably made the greatest contribution to global health of any human intervention apart from the introduction of clean water and sanitation. With new vaccines being developed at an incredible rate to tackle the current pandemic, we take a look at how vaccines work and what goes into each shot.

Karl is joined by Helen Fletcher, Professor of Immunology at LSHTM, to take a look at what goes into a vaccine, how you design one and how the COVID-19 vaccines were created so quickly and safely. They also dispel some of the myths floating around about vaccines.

Professor Beate Kampmann, Director of the Vaccine Centre at LSHTM, also stops by to answer some questions sent in by you, our listeners.

You can find the video on vaccine safety that Karl and Beate talk about here.
