A maelstrom of misinformation and its sinister cousin, disinformation, have been swirling all around us about Covid-19. The rumours and conspiracy theories have raced around the globe as fast as the virus itself.Untruths, half-truths, misunderstandings and deliberate mischief-making aren’t new when it comes to health of course, but a global pandemic with a novel virus means that there is much uncertainty and a lack of definite facts. In that gap, falsehoods flourish and in our super-connected world, they spread far and wide.Claudia Hammond and her panel of global experts assess the scale of misinformation and its impact and conclude that misinformation really does cost lives.Dr Brett Campbell, a physician in a dedicated Covid intensive care unit at Ascension St Thomas Hospital in Nashville, Tennessee, tells Claudia about the unvaccinated patients, many of them close to death, who still cannot accept that the virus is real. Claudia’s guests include Heidi Larson , Director of the Vaccine Confidence Project and Professor at the London School of Hygiene and Tropical Medicine; Dr Saad Omer, Director of the Yale Institute for Global Health and Professor of Medicine and Infectious Diseases in the USA and Robert Kanwagi, a public health specialist and a member of the Global Task Force on Vaccine Confidence and Uptake.
