In late September, Heidi Larson, an anthropologist and the founder of the Vaccine Confidence Project in London, sat on a Zoom call with the project team for Verified, a United Nations-led group that is working to combat a rising tide of misinformation about potential vaccines for Covid-19.
Dr. Larson, 63, is arguably the world’s foremost rumor manager. She has spent two decades in war torn, poor and unstable countries around the globe, as well as in rich and developed ones, striving to understand what makes people hesitant to take vaccines. She is obsessed with the origin and evolution of rumors, which she calls “collective problem solving,” and has come to see most anti-vaxxers — a term she considers too oppositional — not as uneducated, science-denying individualists but as people with genuine questions and doubts in search of guidance. “This is a public cry to say, ‘Is anyone listening?’ she writes in her recently released book “Stuck: How Vaccine Rumors Start and Why they Don’t Go Away.”
These are busy days for a rumor manager, as they are for rumormongers. The Vaccine Confidence Project, which began in 2010, comprises more than a dozen staff with backgrounds in political science, psychology, mathematical modeling, epidemiology and more. They monitor news, social-media outlets and community conversations in nearly every country and in 63 languages, to catch wind of rumors that might undermine the acceptance of critical vaccines. Above all, with hard data gathered from the many surveys and questionnaires the team administers, they have shown that what once seemed like the ghost of a problem is something troublingly tangible and real.
In September, the team published a paper in The Lancet that mapped shifts in vaccine confidence in 149 countries from 2015 through 2019, with data from more than 284,000 adults. For instance, in Indonesia during that period, the perception that vaccines are safe fell from 64 percent to 50 percent after Muslim leaders questioned the safety of the measles, mumps and rubella vaccine and issued a fatwa, or religious ruling, that the vaccine contained forbidden ingredients. In Poland, a highly organized anti-vaccine movement has helped drive down vaccine confidence from 64 percent in November 2018 to 53 percent by December 2019.
