Covid-19 is on the rise again in the UK. After multiple lockdowns and more than 197,000 deaths, experts are warning we're now entering a fifth wave of the pandemic. So why are around four million adults in the UK still yet to receive a single dose of the vaccine? In this timely, eye-opening investigation Professor Hannah Fry seeks to understand why so many remain unvaccinated against Covid-19.

To fully explore this complex and deeply divisive debate, Hannah brings seven unvaccinated participants together under one roof to unpack long-held opinions, beliefs and fears that have prevented them from getting the vaccine. Together, they meet leading experts, confront the latest science and statistics to emerge in the field, and dissect how misinformation spreads on social media. At the end of the experiment, each contributor is asked if what they have learned has changed their mind, and whether they will now take up the vaccine.
